该工作发展的协议为稀疏自旋量子比特阵列的模块化校准和操作奠定了基础,并选择了形成表面码稳定子方格所需的连接方式, 相干自旋穿梭技术的最新进展使得稀疏半导体自旋量子比特阵列成为实现量子处理器的一个颇具吸引力的固态平台, without access to charge sensing in most of the device. We achieve universal control of the effective five-qubit processor and select the connectivity required to form a surface-code stabilizer plaquette that supports X- and Z-type parity checks up to weight four. We use the parity checks to generate multi-qubit entanglement between all qubit combinations in the array and report the genuine entanglement of a five-qubit GreenbergerHorneZeilinger state,该器件包含一条穿梭总线, and we highlight the feasibility of near-term quantum error-correction experiments with mobile spin qubits.

Here we demonstrate a silicon spin-qubit device comprising a shuttling bus for coherently transporting qubits that can interact at four isolated locations that we call bus stops. We dynamically populate the array and tune all single- and two-qubit operations using shuttling and quantum non-demolition spin measurements,并利用穿梭和量子非破坏性自旋测量来调谐所有单量子比特和双量子比特操作,研究组动态填充该阵列。
