[0027] Figure 1 A schematic diagram of the structure of a radio frequency generator provided in an embodiment of the present application is shown in FIG. Figure 1As shown: The embodiment of the present application discloses a radio frequency generator, including a box body 10 with at least one opening and a cover plate 20 arranged at the opening, at least one partition plate 50 is arranged in the box body 10, which is used to divide the box body 10 into multiple isolation chambers 30, and the multiple isolation chambers 30 are used to separate multiple circuits placed in the box body 10; a first wire hole 40 is arranged between the isolation chambers 30, and the first wire hole 40 is used to arrange transmission lines electrically connected between different circuits. In this embodiment, by arranging a partition plate 50 in the box body 10, the box body 10 is divided into multiple isolation chambers 30, so that multiple circuits in the isolation chambers 30 are isolated, avoiding mutual interference between multiple circuits, thereby ensuring the accuracy of the radio frequency signal and realizing precise operation and control of quantum bits.

[0028] Specifically, in this embodiment, the multiple circuits may refer to multiple circuits with different frequencies, or may refer to circuits with the same frequency but still need to be isolated.

[0029] In this embodiment, there is no specific restriction on the location and shape of the first wire-passing hole 40, as long as the transmission lines electrically connected between different circuits can be arranged. Figure 2 Schematic diagram of the structure of three first wire holes 40 provided in the embodiments of the present application; Figure 2 As shown, the specific structures of the three first wire-passing holes 40 are as follows.

[0030] Example 1: Two adjacent partitions 50 are arranged with a gap to form the first wire-passing hole 40, such as Figure 2 As shown in a.

[0031] Example 2: A first groove is formed at one end of the partition 50 close to the box body 10 to form the first wire hole 40. Figure 2 As shown in b; this arrangement can reduce the space of the first wire hole 40 as much as possible, thereby improving the isolation effect.

[0032] Example 3: A card plate is provided at one end of any of the partitions 50 away from the box body 10, and a card slot is provided at one end of the adjacent partition 50 away from the box body 10, and the card plate cooperates with the card slot to form the first wire hole 40 at the end close to the box body 10, such as Figure 2 As shown in FIG. 3 c, such an arrangement can reduce the space of the first wire-passing hole 40 as much as possible, thereby improving the isolation effect.

[0033] In some implementations of this embodiment, the partition plate 50 is provided with a first mounting hole 51 for detachably connecting with the cover plate 20. By providing the first mounting hole 51, the partition plate 50 and the cover plate 20 can be detachably connected together at the first mounting hole 51 by screws, so that a relatively sealed space is formed between the isolation cavity 30 and the cover plate 20 except for the first wire hole 40, further improving the isolation degree of the isolation cavity 30.

[0034] In some implementations of this embodiment, a second groove is provided on the cover plate 20, and the end of the partition plate 50 away from the box body 10 is clamped in the second groove. In this way, a relatively sealed space is formed between the isolation cavity 30 and the cover plate 20 except for the first wire hole 40, thereby further improving the isolation degree of the isolation cavity 30.

[0035] Figure 3 A schematic diagram of the structure of the third isolation plate 60 provided in the embodiment of the present application arranged in the isolation cavity 30; Figure 3 As shown: In some implementations of this embodiment, a third isolation plate 60 is further provided in the isolation cavity 30, and an isolation area is formed between the third isolation plate 60 and the inner wall of the isolation cavity 30 for isolating electronic components that need to be isolated in the circuit.

[0036] In the present embodiment, there is no specific limitation on the shape of the third isolation plate 60 , and the third isolation plate 60 may be U-shaped, L-shaped, trapezoidal or other shapes.

[0037] When the third isolation plate 60 is provided, the electrical connection between the electronic components in the isolation area and the electronic components outside the isolation area can be implemented in the following two ways.

[0038] The first way: a second wire hole can be provided on the third isolation plate 60 for electrically connecting the electronic components in the isolation area with other electronic components outside the isolation area;

[0039] The second method: there is no need to set a second wire hole on the third isolation plate 60, and the circuit is integrated on the PCB board. The PCB board adopts a multi-layer circuit board, and the electronic components in the isolation area are electrically connected to other electronic components outside the isolation area in the middle layer of the multi-layer circuit board, which can further improve the isolation effect.

[0040] In some implementations of this embodiment, the third isolation plate 60 is detachably installed in the isolation cavity 30. Exemplarily, the third isolation plate 60 can be fixed to the bottom plate of the isolation cavity 30 by screws, and a detachable connection can be achieved by providing a mutually cooperating snap-fit ​​structure on the third isolation plate 60 and the wall surface forming the isolation cavity 30.

[0041] In some implementations of this embodiment, the partition 50 is arranged in a direction away from the bottom of the box body 10 in a wide upper part and narrow lower part. The advantages of such an arrangement are: the narrow lower part is convenient for reducing the occupied area of ​​the partition 50 in the box body 10 and facilitating the circuit integration layout; at the same time, the wide upper part is convenient for the fixed connection between the partition 50 and the cover plate 20.

[0042] In this embodiment, the shape and number of the partition 50 are not specifically limited, and are mainly related to the circuit placed therein. When the partition 50 is relatively simple in shape, such as a long strip, the partition 50 can be arranged in a manner of integrally forming the partition 50 with the box body 10, which not only has a good isolation effect, but is also easy to process. When the partition 50 is relatively complex in shape, such as a folded line shape or other special-shaped structure that has been bent multiple times, it is not convenient to directly integrate and process the partition 50. At this time, the partition 50 is arranged in a manner of detachably connecting the partition 50 with the box body 10, which makes the circuit layout more flexible. In some implementations of this embodiment, the partition 50 is provided in plurality, at least one of the partitions 50 is a first isolation plate integrally formed with the box body 10, and at least one of the partitions 50 is a second isolation plate detachably connected to the box body 10. This implementation adopts a method of combining two types of partitions 50, which is a solution obtained by balancing the isolation effect, processing convenience, and circuit layout convenience.

[0043] In some implementations of this embodiment, the RF generator further includes a first PCB board placed in the box body 10, and the plurality of circuits are integrated on the first PCB board. Further, a limiting hole is provided on the first PCB board, and the limiting hole matches the first isolation plate, so that the displacement of the first PCB board in the horizontal direction is limited, and the stability of the first PCB board is enhanced. Further, a second mounting hole for detachably connecting with the box body 10 is provided on the first PCB board, so that the first PCB board can be detachably connected with the box body 10 by passing a screw through the second mounting hole, so that the displacement of the first PCB board in the vertical direction is limited, and the stability of the first PCB board is further enhanced.

[0044] In this embodiment, there is no specific limitation on the shape of the box body 10. In order to improve the integration of the RF generator, in some implementations of this embodiment, the box body 10 includes a hollow cavity enclosed by side panels and a fourth isolation plate 70 arranged in the hollow cavity. The fourth isolation plate 70 divides the hollow box body 10 into a first accommodating cavity and a second accommodating cavity arranged vertically. The partition 50 is arranged in the first accommodating cavity and / or the second accommodating cavity to form a plurality of isolation cavities 30.

[0045] Arranging the multiple isolation cavities 30 in two layers improves the overall integration of the RF generator, making the overall size of the RF generator smaller and suitable for miniaturized design. Of course, multiple fourth isolation plates 70 can also be provided as needed to separate the hollow cavity into multiple layers.

[0046] Further, in this embodiment, when different circuits are arranged in the upper and lower isolation cavities 30, the circuits arranged in the upper isolation cavity 30 are integrated on the second PCB board, and the circuits arranged in the lower isolation cavity 30 are integrated on the third PCB board; Figure 4 A schematic diagram of the structure of the transmission line arrangement in the fourth isolation plate 70 provided in an embodiment of the present application; Figure 4 As shown: At this time, the first wire-passing hole 40 can be a connecting hole arranged in an array on the fourth isolation plate 70, and a transmission line for electrically connecting different circuits is placed in the connecting hole (the transmission line is a connecting core 100 wrapped with an insulating layer 90), and the two ends of the connecting core 100 are respectively welded to the circuits to be connected in the second PCB board and the third PCB board. Furthermore, a thermal conductive adhesive layer 80 is provided in the gap between the insulating layer 90 and the connecting hole, so that the connecting core 100 wrapped with the insulating layer 90 can be firmly placed in the connecting hole, and at the same time, it is also convenient for heat conduction.

The quantum computing measurement and control system of the present application includes the above-mentioned radio frequency generator, and therefore has the same beneficial effects as the above-mentioned radio frequency generator, which will not be repeated here.

[0048] 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, wherein the quantum chip performs quantum computing tasks according to the measurement and control signal provided by the quantum computing measurement and control system. The quantum computer of the present application includes the above-mentioned quantum computing measurement and control system, and therefore has the same beneficial effects as the above-mentioned radio frequency generator, which will not be repeated here.
