Abstract
Combining the long coherence time of hyperfine atomic qubits, the strong
Rydberg dipolar interactions for qubit entanglement, and the scale up
capability using two-dimensional (2D) tweezer arrays for single-atom
trapping, neutral atoms have become a versatile platform for the studies of quantum
computing and quantum simulation. In the past five years, there have been significant
achievements on quantum computing with this platform in the world, e. g. the porotype
quantum computer has been demonstrated recently, a two-qubit gate fidelity of 0.995
has been realized, and a qubit number of above 1000 has been prepared. We are
developing a 2D single-atom array platform to implement multiqubit digital quantum
processor and analog quantum simulator. Our experimental progress will be reported
and future studies on the quantum machine learning, quantum approximate
optimization, and quantum spin models in this platform will be discussed.
