Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0038] In a quantum computer, a function board 1 is usually used to provide a signal source for the control signal required by the quantum chip. Usually, the function board 1 is electrically connected to the quantum chip through a signal line 7. The electrical connection between the signal line 7 and the function board 1 is achieved through a signal connector. In order to facilitate the electrical connection, a plug-in signal connector is usually selected. Although this plug-in method is fast to connect, it is easy to cause the connection to become loose. In addition, due to the gravity of the signal line 7 itself, the signal line 7 is bent at the joint, which is easy to cause the signal line 7 to be damaged at the joint, thereby affecting the stability of the connection and further affecting the transmission quality of the signal.

[0039] To solve the above problems, Figure 1 A schematic diagram of the structure of a signal line integrated component provided in an embodiment of the present application, Figure 2 A schematic diagram of the structure of the functional board 1 provided in the embodiment of the present application; Figure 1 and Figure 2As shown: This embodiment discloses a signal line integrated component, comprising: n signal lines 7, one end of each of the signal lines 7 is electrically connected to a first signal connector 3, the first signal connector 3 is used to be electrically connected to the second signal connector 2 on the function board 1; a pressure block 5, which is detachably mounted on the function board 1, and the pressure block 5 is provided with n first through holes, each of the first through holes accommodates a coaxially arranged elastic member 4, and the elastic members 4 are sleeved on the n signal lines 7 one by one; wherein, when the pressure block 5 is installed on the function board 1, one end of the elastic member 4 is abutted against the first signal connector 3 and the telescopic direction of the elastic member 4 is the same as the axial direction of the first signal connector 3; n is a positive integer greater than or equal to 1.

[0040] In this embodiment, n signal lines 7 are integrated together by setting a pressing block 5; the pressing block 5 is provided with n first through holes, and n coaxially arranged elastic members 4 are placed in the n first through holes. When the pressing block 5 is installed on the functional board 1, one end of the elastic member 4 is arranged in contact with the first signal connector 3 and the expansion and contraction direction of the elastic member 4 is the same as the axial direction of the first signal connector 3, so that when the first signal connector 3 and the second signal connector 2 are plugged in, the elastic member 4 presses the first signal connector 3 along the axial direction of the first signal connector 3 to ensure the installation stability of the first signal connector 3, and the problem of loose connection is not easy to occur; at the same time, the pressing block 5 can reduce the influence of the deadweight of the signal line 7 at the joint on the connection between the first signal connector 3 and the signal line 7, and the problem of damage to the signal line 7 at the joint is not easy to occur, further ensuring the stability of the connection, and then ensuring the signal transmission quality.

[0041] The specific steps of using the signal line integrated component of this embodiment for the function board 1 are as follows:

[0042] The signal lines 7 are passed through the elastic members 4 one by one and then electrically connected to the first signal connectors 3 .

[0043] The first signal connectors 3 are plugged into the second signal connectors 2 in a one-to-one correspondence.

[0044] The pressing block 5 is mounted on the housing of the functional board 1 . At this time, the elastic member 4 in the pressing block 5 is pressed tightly against the first signal connector 3 to ensure the stability of the first signal connector 3 .

[0045] When removing, first remove the connection between the pressing block 5 and the functional board 1, and withdraw the pressing block 5 from the first signal connector 3; then pull the first signal connectors 3 out of the second signal connectors 2 one by one.

[0046] In this embodiment, in the signal line integrated component, the number of signal lines 7 is not specifically limited, and is usually the same as the number of output terminals of the function board 1 (ie, the number of second signal connectors 2); illustratively, Figure 1 and Figure 2 As shown, there are 10 second signal connectors 2 in the functional board 1, and 10 signal lines 7 are integrated in the signal line integrated component, that is, n is 10.

[0047] In this embodiment, in the signal line integrated component, the number and arrangement of the first through holes are not specifically limited, and are usually consistent with the number and arrangement of the output terminals of the function board 1 (i.e., the number and arrangement of the second signal connectors 2). Figure 1 and Figure 2 As shown, there are 10 second signal connectors 2 in the functional board 1, which are arranged in an array along the length direction of the functional board 1. Then, there are 10 first through holes in the signal line integrated component, and the 10 first through holes are arranged in an array along the length direction of the functional board 1. At this time, the pressing block 5 can be in a long strip shape.

[0048] In this embodiment, the type of the elastic member 4 is not specifically limited, and three specific examples are given as follows.

[0049] Example 1: The elastic member 4 is a spring.

[0050] Example 2: The elastic member 4 is an O-shaped elastic ring; specifically, the O-shaped elastic ring includes rubber material.

[0051] Example three, the elastic member 4 is an elastic column, and a second through hole for the signal line 7 to pass through is coaxially provided in the elastic column; specifically, the elastic column includes rubber material.

[0052] In the present embodiment, the accommodation manner of the elastic member 4 in the first through hole is not specifically limited. Specifically, in some implementations of the present embodiment, the other end of the elastic member 4 is fixed to the inner wall of the first through hole; illustratively, the other end of the elastic member 4 is welded or bonded to the inner wall of the first through hole.

[0053] In some other implementations of the present embodiment, a limiting surface is formed in the first through hole, the other end of the elastic member 4 abuts against the limiting surface, and a third through hole is provided on the limiting surface for the signal line 7 to pass through. This ensures that when the pressing block 5 is installed on the functional board 1, one end of the elastic member 4 can abut against the first signal connector 3 to ensure the installation stability of the first signal connector 3. Four specific examples of the limiting surface are given as follows.

[0054] Example 1: Figure 3 A schematic diagram of a first structure in which the elastic member 4 is arranged in the first through hole according to an embodiment of the present application, as shown in FIG. Figure 3 As shown: the first through hole includes a step hole 8, and the step in the step hole 8 forms the limiting surface.

[0055] Example 2: The first through hole comprises a trapezoidal hole, and the limiting surface is formed at a position where the radial dimension of the elastic member 4 is the same as the radial dimension of the trapezoidal hole.

[0056] Example three, the first through hole includes a truncated cone hole, and the limiting surface is formed at a position where the radial dimension of the elastic member 4 is the same as the radial dimension of the truncated cone hole.

[0057] Example 4: Figure 4 A second structural diagram of the elastic member 4 provided in the embodiment of the present application is arranged in the first through hole, as shown in FIG. Figure 4 As shown: a limiting plate 9 for forming the limiting surface is disposed in the first through hole, and the limiting plate 9 is provided with the third through hole for the signal line 7 to pass through.

[0058] In the present embodiment, the installation method of the pressing block 5 detachably installed on the functional board 1 is not specifically limited. In some implementations of the present embodiment, the signal line integrated assembly further includes a fastener 6 for detachably installing the pressing block 5 on the functional board 1; illustratively, the fastener 6 can be a screw, and further, the fastener 6 is a captive screw.

[0059] In this embodiment, the types of the first signal connector 3 and the second signal connector 2 are not specifically limited. In some implementations of this embodiment, the first signal connector 3 and the second signal connector 2 are SMP connectors; or, the first signal connector 3 and the second signal connector 2 are SSMP connectors. Exemplarily, when the second signal connector 2 is a female SMP connector, the first signal connector is a male SMP connector.

[0060] In this embodiment, the material of the pressing block 5 is not specifically limited. For example, the material of the pressing block 5 is gold-plated oxygen-free copper. In a quantum computer of a superconducting quantum system, the quantum chip needs to be in an extremely low temperature environment to achieve relatively excellent working performance. The pressing block 5 is made of gold-plated oxygen-free copper to achieve a better heat conduction effect, which prevents the heat generated by the quantum measurement and control circuit from escaping to the working area of ​​the quantum chip, thereby providing the quantum chip with the extremely low temperature working environment it needs. In order to further improve the heat conduction effect, a heat sink can be set on the outer wall of the pressing block 5.

The quantum measurement and control system of the present application includes the above-mentioned signal line integrated component, and therefore has the same beneficial effects as the above-mentioned signal line integrated component, which will not be repeated here.

[0062] Based on the same application concept, the embodiment of the present application also proposes a quantum computer, including the above-mentioned quantum computing measurement and control system and a quantum chip. The quantum computer of the present application includes the above-mentioned signal line integrated component, and thus has the same beneficial effects as the above-mentioned signal line integrated component, which will not be repeated here.
