Description

Technical Field

[0001] The utility model relates to the technical field of quantum computers, and in particular to an integrated quantum measurement and control circuit, a quantum computing measurement and control system and a quantum computer. Background Art

[0002] Quantum computers are physical devices that follow the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. The main characteristics of quantum computers are fast operation speed, strong information processing capabilities, and a wide range of applications. Among the many quantum computing technology routes, the superconducting technology route has a very broad prospect, and quantum computers developed based on the superconducting technology route have attracted much attention in the industry. The core computing element of a superconducting quantum computer, the quantum chip, needs to work in an extremely low temperature environment, such as millikelvin temperature. The extremely low temperature environment is generally provided by a dilution refrigerator, and the quantum chip is installed at the lowest temperature of the dilution refrigerator. In order to control and measure the quantum chip at the bottom layer, a line carrying quantum measurement and control signals needs to enter the dilution refrigerator, pass through each cold plate of the dilution refrigerator in turn, and connect to the quantum chip in the lowest temperature zone. These lines that control and measure the quantum bits in the quantum chip are called quantum measurement and control lines.

[0003] The control of quantum bits depends on high-precision analog input signals, and each quantum bit requires the application of several control signals. The control signals of quantum bits are generated by various functional boards in the quantum measurement and control device, and the generated control signals are transmitted to the quantum chip through the room temperature plate of the dilution refrigerator and the measurement and control lines of each layer of cold plate.

[0004] As the number of quantum bits integrated on a quantum chip increases, the number of measurement and control circuits will also increase. However, the dilution refrigerator that provides a low-temperature environment for the quantum chip is limited in size, and the layout of the measurement and control circuits becomes more difficult. The measurement and control circuits are prone to crossover and confusion, which greatly limits the expansion of quantum measurement and control circuits, and thus limits the expansion of quantum computers. Therefore, it is urgent to provide a measurement and control circuit with neat wiring and high integration.

[0005] It should be noted that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art.

[0029] Figure 1 A schematic diagram of the structure of an integrated quantum measurement and control circuit provided by an embodiment of the utility model; Figure 1As shown: The embodiment of the present application discloses an integrated quantum measurement and control circuit, including several measurement and control line integrated modules, each measurement and control line integrated module includes: several coaxially arranged wire drums 10 and several adapters arranged in an array on each wire drum 10, wherein each of the wire drums 10 is installed one-to-one on the room temperature disk 71 and several cold disks 72 of the dilution refrigerator 70; several first cables 20 arranged between the wire drum 10 fixed on the room temperature disk 71 and the function board 80; several second cables 30 arranged in parallel between any two adjacent wire drums 10; several third cables 40 arranged between the wire drum 10 fixed on the cold disk 72 with the lowest temperature and the quantum chip 90; wherein the several first cables 20, the several second cables 30, and the several third cables 40 are electrically connected one-to-one through the adapter to form a measurement and control line integrated module containing several quantum measurement and control circuits.

[0030] In the present application, the first cable 20, the second cable 30 and the third cable 40 in the measurement and control circuit are integrated on the coaxially arranged cable reel 10 through an array-arranged adapter, which not only improves the integration of the cables in the measurement and control circuit, but also facilitates wiring, thereby ensuring the regularity of the cable arrangement inside the dilution refrigerator 70.

[0031] For example, Figure 1 As shown, Figure 1 A measurement and control line integrated module is provided in the dilution refrigerator 70 (exemplarily, the dilution refrigerator 70 includes 1 room temperature disk and 4 cold disks), and the measurement and control line integrated module includes 5 coaxially arranged wire drums 10; 5 first cables 20 arranged between the wire drum 10 fixed on the room temperature disk 71 and the function board 80; 5 second cables 30 arranged in parallel between any two adjacent wire drums 10; 5 third cables 40 arranged between the wire drum 10 fixed on the cold disk 72 with the lowest temperature and the quantum chip 90; the 5 first cables 20, 4 groups of 5 second cables 30, and 5 third cables 40 are electrically connected one by one through an adapter to form a measurement and control line integrated module including 5 quantum measurement and control circuits.

[0032] In addition, the number of the first cable 20, the second cable 30, and the third cable 40 in each measurement and control line integrated module corresponds to each other. For example, a quantum measurement and control line is realized by electrically connecting a first cable 20, a second cable 30 between any two cable drums 10, and a third cable 40 through an adapter on each cable drum 10. The number of cables in each measurement and control line integrated module is determined according to multiple influencing factors such as the signal interface of the quantum chip 90, the type of signal transmitted on the cable, and the size of the cable drum 10. The 5 cables in the drawings in this embodiment are only examples.

[0033] Generally, three types of functional boards 80 are involved in quantum computing, namely, quantum state control board, frequency control board, and measurement board. The quantum state control board is used to provide quantum state control signals for quantum bits. The frequency control board is used to provide frequency control signals for quantum bits. The measurement board is used to provide measurement reading signals for quantum bits.

[0034] In this embodiment, the integrated quantum measurement and control circuit can be installed in the dilution refrigerator 70 in the following two ways:

[0035] The first method is to install a plurality of cable reels 10 on the room temperature reel 71 and the cold reel 72 respectively, and then install the first cable 20 , the second cable 30 and the third cable 40 .

[0036] The second method is: first integrate the measurement and control line integrated module on the support frame 100, and then install it. Figure 2 A schematic diagram of the structure of the support frame 100 provided in an embodiment of the present utility model; Figure 2 As shown: the support frame 100 includes a connecting rod 101 and a plurality of supporting plates 102 vertically arranged on the connecting rod 101, and the supporting plate 102 is provided with an installation opening 103; a plurality of the cable drums 10 are correspondingly and detachably installed at the installation openings 103 of the plurality of the supporting plates 102. By setting the support frame 100, the cable drums 10 are fixed together, and a plurality of cable drums 10 in the measurement and control line integrated module can be integrated together, which is not only convenient for transportation, but also convenient for installation; specifically, the cable drums 10 are first installed one by one on the supporting plate 102, and then the first cable 20, the second cable 30 and the third cable 40 can be conveniently installed when the connecting rod 101 is placed horizontally, so that a measurement and control line integrated module is formed; finally, the connecting rod 101 is placed vertically, and the cable drums 10 are correspondingly installed on the room temperature plate 71 and the cold plate 72, and then the support frame 100 is removed, which is not only convenient for installation, but also improves the installation efficiency. Furthermore, a handle 104 is provided on the connecting rod 101. By providing the handle 104, the installation tool can be easily lifted so that the connecting rod 101 is in a vertical state.

[0037] Furthermore, in some implementations of the present embodiment, the wire reels 10 of each of the measurement and control line integrated modules are symmetrically arranged around the quantum chip 90 in a vertical direction of the extension plane of the quantum chip 90; multiple signal interfaces of the quantum chip 90 are usually symmetrically arranged on the periphery of the chip substrate or the packaging box, and the wire reels of each of the measurement and control line integrated modules are symmetrically arranged around the quantum chip 90, which facilitates the electrical connection between the third cable 40 in each of the measurement and control line integrated modules and the signal interface of the quantum chip, thereby ensuring the regularity of the cable arrangement inside the dilution refrigerator 70.

[0038] In this embodiment, the specific materials and shapes of the first cable 20, the second cable 30, and the third cable 40 are not specifically limited. Preferably, the second cable 30 includes a semi-steel wire, which ensures that the second cable 30 has strong mechanical strength and tensile strength, and at the same time, has a certain pressure resistance. Preferably, the second cable 30 includes at least one section of S-shaped cable or O-shaped cable or V-shaped cable or U-shaped cable; it not only improves the tensile strength and flexibility of the second cable 30, but also improves the convenience of installation, and can be easily installed between two cable drums 10 at different distances. Preferably, the third cable 40 includes a flexible wire; because the flexible wire is easy to bend, it is convenient to install it between the cable drum 10 and the quantum chip 90.

[0039] Usually, in order to ensure the accuracy of signal transmission, microwave devices, such as attenuators or filters or amplifiers or circulators, are provided in the measurement and control circuit. Usually, these microwave devices are arranged one by one on the second cable 30 or the third cable 40. As the number of the second cable 30 and the third cable 40 increases, the number of microwave devices will also increase, which will occupy more space. Based on this, the present application proposes a preferred implementation mode, the measurement and control line integrated module also includes a first multi-channel integrated microwave device plugged between a number of the second cables 30 and a number of adapters and / or a second multi-channel integrated microwave device 60 plugged between a number of the third cables 40 and a number of adapters. Specifically, the first multi-channel integrated microwave device and the second multi-channel integrated microwave device 60 in this embodiment can be a plurality of microwave device circuits integrated together, each microwave device circuit corresponds to an independent output channel, and each output channel is electrically connected to a cable in a measurement and control circuit. By adopting a multi-channel integrated microwave device, the integration of microwave devices in the measurement and control circuit is realized, and the occupied area of ​​the microwave device is reduced. Further, the first multi-channel integrated microwave device includes at least one of a multi-channel integrated attenuator, a multi-channel integrated filter, a multi-channel integrated amplifier or a multi-channel integrated circulator; the second multi-channel integrated microwave device 60 includes at least one of a multi-channel integrated attenuator, a multi-channel integrated filter, a multi-channel integrated amplifier or a multi-channel integrated circulator.

[0040] Preferably, the housing of the first multi-channel integrated microwave device can be detachably mounted on the adjacent cable drum 10 or the housing of the adjacent first multi-channel integrated microwave device; exemplarily, when only the first multi-channel integrated attenuator is provided between a cable drum 10 and a plurality of second cables 30, after the first multi-channel integrated attenuator is plugged into the adapter in the cable drum 10, its housing can be detachably mounted on the cable drum 10 by screws. Exemplarily, when the first multi-channel integrated attenuator and the first multi-channel integrated filter are provided between a cable drum 10 and a plurality of second cables 30, after the first multi-channel integrated attenuator is plugged into the adapter in the cable drum 10, its housing can be detachably mounted on the cable drum 10 by screws; the first multi-channel integrated filter is plugged between the first multi-channel integrated attenuator and a plurality of second cables 30, and its housing can be detachably mounted on the housing of the first multi-channel integrated attenuator by screws. This improves the integration and ensures the reliability of installation.

[0041] Preferably, the housing of the second multi-channel integrated microwave device 60 is detachably mounted on the adjacent cable drum 10 or on the housing of the adjacent second multi-channel integrated microwave device 60. Exemplarily, when only the second multi-channel integrated attenuator is provided between the cable drum 10 and the plurality of third cables 40, after the second multi-channel integrated attenuator is plugged into the adapter in the cable drum 10, its housing is detachably mounted on the cable drum 10 by screws. Exemplarily, when the second multi-channel integrated attenuator and the second multi-channel integrated filter are provided between the cable drum 10 and the plurality of third cables 40, after the second multi-channel integrated attenuator is plugged into the adapter in the cable drum 10, its housing is detachably mounted on the cable drum 10 by screws; the second multi-channel integrated filter is plugged between the second multi-channel integrated attenuator and the plurality of third cables 40, and its housing is detachably mounted on the housing of the second multi-channel integrated attenuator by screws. This improves the integration and ensures the reliability of the installation.

[0042] For example, Figure 1 The measurement and control line integrated module includes only one second multi-channel integrated microwave device 60.

[0043] In the present application, since there is not only a horizontal distance difference but also a height difference between the room temperature disk 71 of the dilution refrigerator 70 and the function board 80, the first cable 20 has a certain length, which is not only inconvenient to install the first cable 20, but also prone to wiring confusion. In order to avoid the above problems, Figure 3 A schematic diagram of the structure of a plurality of first cables 20 integrated according to an embodiment of the present utility model; Figure 3As shown: In some implementations of the present embodiment, a plurality of first cables 20 include a plurality of first sub-cables 21, a plurality of second sub-cables 22, a first multi-channel connector 23 and a second multi-channel connector 24; wherein, the first ends of the plurality of first sub-cables 21 are electrically connected to a plurality of adapters in a cable drum 10 located on a room temperature drum 71, and the second ends of the plurality of first sub-cables 21 are integrated into at least one of the first multi-channel connectors 23; the first ends of the plurality of second sub-cables 22 are integrated into at least one of the second multi-channel connectors 24, and the second ends of the plurality of second sub-cables 22 are electrically connected to a functional board 80; and the first multi-channel connector 23 is plugged into and matched with the second multi-channel connector 24.

[0044] By dividing the first cable 20 into two sections, a first sub-cable 21 and a second sub-cable 22, the inconvenience of installation caused by the first cable 20 being too long is avoided, the second ends of several first sub-cables 21 are integrated into at least one of the first multi-channel connectors 23, and the first ends of several second sub-cables 22 are integrated into at least one of the second multi-channel connectors 24. The first multi-channel connector 23 and the second multi-channel connector 24 are plugged together, so that the electrical connection of several first sub-cables 21 and several second sub-cables 22 can be quickly achieved, and at the same time, wiring confusion can be avoided.

[0045] Furthermore, the first sub-cable 21 integrated through the same first multi-channel connector 23 is electrically connected to the same cable reel 10, and the second sub-cable 22 integrated through the same second multi-channel connector 24 is electrically connected to the same functional board 80, further ensuring the regularity of the wiring and avoiding wiring confusion.

[0046] Further, the housing of the first multi-channel connector 23 and / or the second multi-channel connector 24 is detachably fixed to the adapter plate, and the adapter plate is detachably fixed to the frame of the dilution refrigerator 70. By providing the adapter plate to integrate the plurality of first multi-channel connectors 23 and second multi-channel connectors 24 together, not only the integration is improved, but also the adapter plate plays a load-bearing role, thereby avoiding the phenomenon of unstable signals at the cable joints due to the gravity of the cables, or even damage to the lines or joints.

[0047] Further, in some implementations of this embodiment, continue as Figure 3 As shown: the second end of the second sub-cable 22 is electrically connected to the functional board 80 by setting a fourth connector 26, and the first ends of several first sub-cables 21 are provided with several third connectors 25 plugged with several of the adapters, and the several third connectors 25 are integrated on at least one integrated board 27. By setting the integrated board 27, not only the integration is improved, but also it is convenient to install several third connectors 25 on the cable reel 10 at the same time.

[0048] Figure 4 A schematic diagram of the structure of the integrated board 27 provided in the embodiment of the utility model; Figure 4 As shown: In some implementations of this embodiment, the specific structure of the integrated board 27 is as follows: the integrated board 27 includes a first clamp block 271 and a second clamp block 272 that are detachably fixedly connected, and the first clamp block 271 and the second clamp block 272 are closed to form a plurality of receiving holes 273 distributed along the length direction of the first clamp block 271 for accommodating the third connector 25. The integrated board 27 of this structure can realize the integration of several third connectors 25 conveniently and quickly.

[0049] Further, each receiving hole 273 is provided with a first positioning groove 275, and the outer wall of each third connector 25 is provided with a protrusion matching the first positioning groove 275; by providing the first positioning groove 275 and the protrusion, each third connector 25 can be quickly positioned on the integrated board 27. Further, the first clamping block 271 and the second clamping block 272 are provided with mutually matching positioning columns 276 and second positioning grooves 277, which can realize the rapid positioning of the first clamping block 271 and the second clamping block 272. Further, the first clamping block 271 and the second clamping block 272 in the integrated board 27 can be fixed together by fasteners (such as screws). Specifically, fasteners are arranged between two adjacent receiving holes 273 on the integrated board 27, so as to ensure that each third connector 25 is clamped in the integrated board 27. Further, the inner wall of the receiving hole 273 is provided with an elastic layer 274, which is exemplarily an elastic rubber layer, to further ensure the reliability of the installation of the third connector 25.

[0050] Furthermore, in some implementations of the present embodiment, after the third connector 25 in the integrated board 27 is integrated and plugged into the adapter in the cable reel 10, in order to further ensure the reliability of the connection, both ends of the integrated board 27 are detachably fixed to the cable reel 10 by fasteners. Exemplarily, the fasteners are screws.
