我们展示了纠缠量子门内的五个被困离子量子比特链的最佳成形耦合到多个集体运动模式的光场。我们利用分段的光脉冲分别寻址量子比特，以可编程的方式构造多体纠缠态。这种方法使高保真门能够扩展到更大的量子位寄存器，用于量子计算和模拟。
We demonstrate entangling quantum gates within a chain of five trapped ion qubits by optimally shaping optical fields that couple to multiple collective modes of motion. We individually address qubits with segmented optical pulses to construct multipartite entangled states in a programmable way. This approach enables high-fidelity gates that can be scaled to larger qubit registers for quantum computation and simulation.
