-含可控耦合器的10比特一维链器件

首先我设计了可调耦合的多比特量子芯片，量子计算机实现的是基于单比特门和双比特门的可编程计算。要求单比特门和双比特门具有高的保真度。引入可调耦合器之后将可以在单比特门操作时，无需再调开邻近比特，提升其保真度。双比特门操作时可关断之间耦合消除操作时带来的相位积累，从而提高保真度。双比特之间可任意调动并可关断，也为量子计算或模拟引入更多自由度。因此，两比特间耦合强度的可调及关断至关重要。First, I designed a multi-qubit quantum chip with tunable coupling, which enables the quantum computer to perform programmable computing based on single-qubit and two-qubit gates. High fidelity of both single-qubit and two-qubit gates is a core requirement. By introducing the tunable coupler, the fidelity of single-qubit gate operations can be improved, as there is no need to detune neighboring qubits during the operation. During two-qubit gate operations, turning off the inter-qubit coupling can eliminate the phase accumulation induced by the operation, further enhancing the gate fidelity. The capability to arbitrarily adjust and turn off the coupling between two qubits also introduces additional degrees of freedom for quantum computing and quantum simulation. Thus, the tunability and turn-off functionality of the coupling strength between two qubits are critically important.
