Technical Field

[0001] The present application belongs to the field of quantum, especially the field of quantum computing technology, and in particular to an integrated device and quantum computer used in a dilution refrigerator. Background Art

[0002] Quantum computing is a new computing model that follows the laws of quantum mechanics to control basic information units for computing. The basic information unit of classical computing is the classical bit, and the basic information unit of quantum computing is the quantum bit. The classical bit can only be in one state, that is, 0 or 1, but based on the principle of quantum mechanics superposition, the state of the quantum bit can be in a superposition state of multiple possibilities. Therefore, the computing efficiency of quantum computing far exceeds that of classical computing.

[0003] In a quantum computer of a superconducting system, the quantum processor needs to work in an extremely low temperature environment, such as around 10mK. In order to control and measure the bottom-level quantum bits, a cable carrying quantum measurement and control signals needs to pass through the bottom-level cooling plate of the dilution refrigerator and enter the Mixed Chamber (MXC); at the same time, various corresponding electronic devices need to be applied to the cable to process and optimize the quantum measurement and control signals, such as attenuators, filters, amplifiers, synthesizers, etc.

[0004] The quantum measurement and control circuits used to manipulate and measure quantum bits include DC drive signal circuits, pulse drive signal circuits, microwave drive signal circuits, etc. As the number of quantum bits on the quantum processor increases, the quantum measurement and control circuits need to increase accordingly, and the number of applied electronic devices also increases accordingly, especially at the bottom refrigeration plate, where the number and types of electronic devices required are greater.

[0039] The following detailed description is illustrative only and is not intended to limit the embodiments and / or the application or use of the embodiments. In addition, there is no intention to be bound by any express or implied information presented in the foregoing "Background Art" or "Summary of the Invention" section or "Detailed Implementation Manner" section.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, one or more embodiments will now be described with reference to the accompanying drawings, in which like reference numerals are used throughout to refer to like components. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of one or more embodiments. However, it is evident that one or more embodiments may be practiced without these specific details, and the various embodiments may be combined and cross-referenced with each other on the premise of not being contradictory.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0042] Combined Figure 1 and Figure 2 As shown, the integrated device used in the dilution refrigerator in the embodiments of this application specifically includes a support member 1, a transfer board 2 fixedly connected to the support member 1, a plurality of first fixing members 3, and a second fixing member 5; the transfer board 2 includes a first integrated area 21 provided with a first signal transferrer 211 at the center and a plurality of second integrated areas provided with second signal transferrers 221, and the plurality of second integrated areas 22 are arranged around the first integrated area 21. Among them, the first signal transferrer 211 is used to transfer the first microwave signal line for manipulating the quantum state, and the second signal transferrer 221 is used to transfer the DC signal line and the pulse signal line; the first fixing member 3 is located below the second integrated area 22 and is used to fix the signal synthesizer 4 for processing the DC signal line and the pulse signal line; the second fixing member 5 is located below the first integrated area 21 and is used to fix the quantum processor.

[0043] The currently commonly used refrigeration equipment is a dilution refrigerator, which adopts a hierarchical refrigeration technology. In the extremely low temperature region, the phase change endothermic of helium element is used for further refrigeration to obtain an extremely low temperature region, such as 10 mK. The extremely low temperature environment can effectively reduce the influence of thermal noise on the quantum processor. The integrated device of the embodiment of the present application is arranged in the extremely low temperature region. A refrigeration disk 6 is arranged in the extremely low temperature region of the dilution refrigerator. The support member 1 is vertically arranged and fixedly connected with the refrigeration disk 6. While the support member 1 is used to fix the adapter board 2, several first fixing members 3, and the second fixing member 5, it is also used to transfer the cold quantity of the refrigeration disk 6 to the adapter board 2, several first fixing members 3, and the second fixing member 5 for heat dissipation.

[0044] As Figure 1 shown, a plurality of wire inlet holes for the quantum measurement and control circuit to pass through are formed on the refrigeration disk 6. The quantum measurement and control circuit is connected to the first signal adapter 211 in the first integration area 21 and several second signal adapters 221 in the second integration area 22 on the adapter board 2 through the wire inlet holes. Among them, the first microwave signal line for manipulating the quantum state is connected to the first signal adapter 211, and the DC signal line and the pulse signal line for adjusting the working frequency are connected to the second signal adapter 221. By arranging several second integration areas 22 on the adapter board 2, the quantity requirements of the DC signal line and the pulse signal line are met, and the arrangement of the first integration area 21 and the second integration area 22 can separate different types of quantum measurement and control circuits to avoid confusion of the quantum measurement and control circuits.

[0045] Specifically, for the first integration area 21, the first microwave signal line is connected to the first signal adapter 211 in the first integration area 21, and the first signal adapter 211 is connected to the signal port of the quantum processor located below on the second fixing member 5 through a cable. The types, lengths, and shapes of the cables are the same, which are easy to connect and install. For the second integration area 22, several first fixing members 3 are arranged below the second signal adapter for installing a signal synthesizer 4 for synthesizing the DC signal line and the pulse signal line. By making the signal ports of the signal synthesizer 4 correspond to the positions of the second signal adapters 221 in the second integration area 22 one by one, it is ensured that the types, lengths, and shapes of the cables connecting the signal ports of the signal synthesizer 4 and the second signal adapters 221 are the same, and the other end of the signal synthesizer 4 is uniformly connected to the quantum processor, making the cable connection and installation difficultly low and greatly improving the cable connection efficiency of the mixing chamber in the dilution refrigerator.

[0046] Among them, Figure 2The first integrated area 21 and the second integrated area 22 in it are only schematic range areas. Since the number of bits of the quantum processor is different, the number of first microwave signal lines required will also be different. Correspondingly, the range of the first integrated area 21 on the adapter board 2 where the first signal adapter 211 is provided will also be different. The same applies to the second integrated area 22. In this embodiment, the integrated areas on the adapter board 2 are divided according to the type and specific quantity of the quantum measurement and control lines, and the corresponding first signal adapter 211 and second signal adapter 221 are arranged in the integrated areas to meet the requirements of the quantum processor with the corresponding number of bits.

[0047] As Figure 2 shown, as an implementation manner of the embodiment of the present application, several second integrated areas 22 are symmetrically arranged on the adapter board 2. The quantum processor is located on the second fixing member 5 below the first integrated area 21. The several second integrated areas 22 are arranged around the first integrated area 21 to ensure that the DC signal lines and pulse signal lines connected to the second integrated areas 22 are arranged around the quantum processor, which is easy for cable connection. Moreover, by symmetrically arranging, it is ensured that the weight is evenly distributed after the quantum measurement and control lines are connected on the adapter board 2, improving the stability of the adapter board 2.

[0048] Combined with Figure 1 and Figure 2 shown, as an implementation manner of the embodiment of the present application, the first signal adapter 211 of the first integrated area 21 and the second signal adapter 221 of the second integrated area 22 are both arranged in an array on the adapter board 2. Specifically, a number of through holes are arrayed in both the first integrated area and the second integrated area on the adapter board 2. The first signal adapter 211 passing through the adapter board 2 is installed on the through holes in the first integrated area, and the second signal adapter 221 passing through the adapter board 2 is installed on the through holes in the second integrated area. Among them, SMA-type connectors are provided at both ends of the first signal adapter 211 and the second signal adapter 221. The SMA connector at one end of the upper panel of the adapter board 2 is connected to the first microwave signal line, DC signal line or pulse signal line, and the SMA connector at the other end passing through the adapter board 2 is connected to the quantum processor or the signal synthesizer 4.

[0049] It should be added that the SMA connectors at the other ends of the first signal adapter 211 and the second signal adapter 221 can also be first connected to attenuators or filters, and then connected to the quantum processor or the signal synthesizer 4 through cables. The specific situation needs to be selected according to the drive signals transmitted in the quantum measurement and control lines.

[0050] As Figure 3As shown, as an implementation manner of the embodiment of the present application, the second integration area 22 includes a plurality of adjacent sub-areas 221, and the second signal adapters 221 of adjacent sub-areas 221 are respectively used to connect the DC signal line and the pulse signal line.

[0051] The second integration area 22 is used to connect the DC signal line and the pulse signal line. The second integration area 22 is divided into a plurality of adjacent sub-areas 221. Each sub-area 221 is used to connect a type of quantum measurement and control line, such as a DC signal line or a pulse signal line; and adjacent sub-areas 221 are used to connect different types of quantum measurement and control lines.

[0052] Exemplarily, Figure 4 For Figure 3 The schematic diagram of a second integration area 22 at position A of the transfer board 2 is divided into 3 sub-areas 221. It is divided into multiple sub-areas 221 from the inside to the outside along the center position of the transfer board 2. A plurality of second signal adapters 221 are arranged in an array in each sub-area 221. Among them, adjacent sub-areas 221 are connected to different types of quantum measurement and control lines. Taking Figure 5 the said sub-area 221 as an example, the second signal adapter 221 in the innermost sub-area 221 is connected to the DC signal line, the second signal adapter 221 in the middle sub-area 221 is connected to the pulse signal line, and the second signal adapter 221 in the outermost sub-area 221 is connected to the DC signal line.

[0053] Exemplarily, Figure 5 For Figure 3 The schematic diagram of a second integration area 22 at position B of the transfer board 2 is divided into 2 sub-areas 221. The second signal adapter 221 in the inner sub-area 221 is connected to the DC signal line, and the second signal adapter 221 in the outermost sub-area 221 is connected to the DC signal line. By setting adjacent sub-areas 221 and connecting the second signal adapters 221 in the sub-areas to different types of DC signal lines and pulse signal lines respectively, it is ensured that the signal ports of the signal synthesizer 4 below the sub-area 221 are connected to the DC signal line and the pulse signal line through cables, avoiding the winding of the cables due to the position of the signal ports of the signal synthesizer 4, making the cable connection method in the integrated device simple and easy to wire.

[0054] Combined with Figure 1 and Figure 6As shown, as an implementation manner of the embodiment of the present application, the signal input ports of the signal synthesizer 4 respectively correspond to the second signal adapters 221 in the adjacent sub-region 221. The signal synthesizer 4 has a plurality of signal input ports, and each signal input port is respectively connected to the second signal adapter 221 in the sub-region 221 at the corresponding position above. The positions of the signal input ports and the second signal adapter 221 correspond to each other, and they can be connected through a cable. The shape of the cable is simple and there is no need for winding, so the installation and connection efficiency are high.

[0055] As Figure 6 Shown, as an implementation manner of the embodiment of the present application, the first fixing members 3 are stacked, and the signal synthesizer 4 fixed by the first fixing member 3 corresponds to the position of the second signal adapter 221. A plurality of first fixing members 3 are arranged below the transfer board 2 to fix the signal synthesizer 4. The plurality of first fixing members 3 are vertically arranged and fixedly connected to the support member 1. Among them, the plurality of first fixing members 3 are stacked in the vertical direction. By providing multiple layers of first fixing members 3, more signal synthesizers 4 can be fixed, meeting the integration requirements of more quantum measurement and control circuits.

[0056] In addition, the signal synthesizer 4 fixed on the stacked plurality of first fixing members 3 is connected to the second signal adapter 221 in the second integration region 22 above through a cable. The signal synthesizer 4 fixed by the first fixing member 3 corresponds to the array position of the second signal adapter 221, ensuring that after the signal synthesizer 4 is installed on the first fixing member 3, the positions of the signal synthesizer 4 and the second signal adapter 221 in the vertical direction correspond to each other. The two ends of the cable can be respectively connected to the signal synthesizer 4 and the second signal adapter 221 corresponding up and down, avoiding multiple winding, improving the simplicity of the cable and the cable connection efficiency.

[0057] As Figure 6 Shown, as an implementation manner of the embodiment of the present application, the sizes of the stacked first fixing members 3 are increased or decreased in equal proportion. The plurality of first fixing members 3 are stacked, and the sizes of the plurality of first fixing members 3 are changed in equal proportion to ensure that after the first fixing member 3 fixes the signal synthesizer 4, the signal ports of the multiple signal synthesizers 4 are staggered from each other and correspond to the positions of the second signal connectors 221 in the second integration region 22. The cable can directly connect the signal ports of the signal synthesizer 4 and the second signal connectors 221, improving the cable connection efficiency.

[0058] As an implementation manner of the embodiment of the present application, the shape of the first fixing member 3 includes a C shape or a U shape. The C-shaped or U-shaped structure can facilitate the installation of the signal synthesizer 4 and the connection between the signal synthesizer 4 and the cable. At the same time, the space of the first fixing member 3 can be fully utilized, and multiple first fixing members 3 can be arranged on the support member 1 according to actual needs. In addition, the shape of the first fixing member 3 can also include other shapes, such as an L shape.

[0059] In addition, a plurality of mounting holes for mounting the signal synthesizer 4 are formed in the first fixing member 3, and the signal synthesizer 4 is mounted on the outer side surface of the first fixing member 3 by means of screws or bolts, so that the signal ports of the signal synthesizer 4 face outward, facilitating the connection of the cable.

[0060] Such as Figure 7 As shown, as an implementation manner of the embodiment of the present application, a third signal adapter 222 for connecting a second microwave signal line is further provided on one side of the second integration area 22 away from the first integration area 21. The quantum state information of the qubits integrated on the quantum processor needs to be measured by microwave signals. Specifically, a third signal adapter 222 for connecting a second microwave signal line is provided on the adapter board 2, and the second microwave signal is transmitted to the measurement bus on the quantum processor through the third signal adapter 222, and multiple qubits are measured through the measurement bus. Therefore, the number of second microwave signals that need to be applied is small. A plurality of rows or columns of third signal adapters 222 are provided on one side of the second integration area 22 away from the first integration area 21 to connect the second microwave signal line to realize the measurement of the qubits.

[0061] Such as Figure 8 As shown, as an implementation manner of the embodiment of the present application, it further includes a plurality of third fixing members 7 arranged in parallel with the support member and fixedly connected to the adapter board. The third fixing member is used to fix the electronic device 8 electrically connected to the third signal adapter 222. Among them, the third fixing members 7 are symmetrically arranged around the adapter board 2. Specifically, the third fixing members 7 are symmetrically arranged on the side of the outer edge of the adapter board 2 away from the third signal adapter 222. When measuring the quantum processor through the second microwave signal line, various electronic devices 8 for processing the measurement signals, such as circulators, amplifiers, etc., also need to be arranged in the line.

[0062] Such as Figure 9As shown, as an implementation manner of the embodiment of the present application, a first through hole 11 is provided on the support member 1, and the first through hole 11 is for the DC signal line or the pulse signal line or the first microwave signal line to pass through. A second through hole 12 is provided on the support member 1, and the second through hole 12 is for the cable connecting the second signal adapter 221 and the signal synthesizer 4 to pass through. Specifically, the first through hole 11 is opened at a position between the refrigeration plate 6 and the adapter plate 2 on the support plate 1, and the second through hole 12 is opened at a position between the adapter plate 2 and the first fixing member 3 on the support plate 1.

[0063] Based on the same inventive concept, an embodiment of the present application further provides a quantum computer, including a dilution refrigerator, the integrated device as described above located in the dilution refrigerator, and a quantum processor.

The above are only the preferred embodiments of the present application, but the present application is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present application, or equivalent embodiments modified to equivalent changes, still within the spirit covered by the specification and drawings, should be within the protection scope of the present application.
