Abstract

The invention discloses an ion trap system, which comprises an ion trap and a vacuum cavity provided with a first optical window, wherein the vacuum cavity is further provided with a pair of second optical windows which are symmetrically distributed, the centers of the second optical windows and the center of the first optical window are located on the same plane, the first optical window provides an optical path for executing first operation, the second optical window provides an optical path for executing second operation, and the second optical window is larger than the first optical window. According to the embodiment of the invention, the pair of second optical windows used for executing the second operation are symmetrically distributed in the plane of the first optical window, so that an optical path is provided for executing the second operation, and the feasibility of executing the second operation is improved.

Description

technical field [0001] This paper relates to, but is not limited to, quantum computer technology, especially an ion trap system. Background technique [0002] Quantum computer mainly refers to general-purpose equipment that realizes general-purpose quantum computing and quantum simulation through the operation of quantum logic gates. It is still in the development and testing stage of the prototype at this stage. At present, the main physical experimental platforms for physically realizing quantum computers include ion traps, superconductors, and diamond color centers. The basic logic unit is composed of qubits that obey the principles of quantum mechanics. Physically realize a quantum computer. Compared with traditional computers, the calculation time of quantum computers can be greatly reduced when solving some specific problems. Quantum computers composed of small-scale qubits can already complete some calculation tasks that cannot be realized by traditional computers; t...
