摘要
Quantum computing is attracting significant attention due to its potential for solving classically intractable problems. Current leading platforms include the superconducting qubits and trapped ions, with achieved qubits number around 50-100 and average two-qubit gate fidelity of >99%. 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 atoms to highly excited Rydberg states, which exhibit strong and long-range interactions. A two-qubit gate fidelity of ~ 98% has been achieved recently. Prototype quantum computers based on this platform have been demonstrated recently by two groups [1,2]. In this talk, I will introduce the status and our research plan along this direction.
