| 摘要 | Quantum computing is attracting significant attention due to its potential for solving classically intractable problems. However, its realization is notoriously difficult due to the requirement on accurate control of the strong interactions between large-scale qubits while maintaining weak coupling to the environment. Current leading platforms include the superconducting qubits and trapped ions, with achieved qubits number around 50 and average fidelity of two-qubit gates around 99%. To enable useful applications, significant improvements on these figure of merits are required. Recently, individual atoms trapped in optical tweezer arrays have emerged as one of the versatile platforms for quantum computing and simulation. Defect-free qubit numbers of a few hundreds have been routinely generated. Two qubit gates are implemented by coherent driving to highly excited Rydberg states, which exhibit strong and long-range interactions and a fidelity of around 98% has been achieved recently. While large-scale gate-based quantum circuits still wait to be demonstrated, this platform has been used to simulate quantum spin models in regimes beyond those accessible via numerical studies with modern supercomputer. In this talk, I will introduce the status and our future plan for the research along this direction. |
