Branch-resolved Pauli-block spectroscopy of residual conditional phase in two-qubit gates
Xudan Chai, Yanwu Gu, Huiqi Xue +2
Recent progress in quantum physics and quantum technologies is driving quantum computing from the noisy intermediate-scale (NISQ) era toward fault-tolerant operation. High-precisio…
Multi-qubit State Tomography with Few Pauli Measurements
Xudan Chai, Teng Ma, Qihao Guo +3
In quantum information transformation and quantum computation, the most critical issues are security and accuracy. These features, therefore, stimulate research on quantum state ch…
Quafu-Qcover: Explore Combinatorial Optimization Problems on Cloud-based Quantum Computers
BAQIS Quafu Group
We present Quafu-Qcover, an open-source cloud-based software package designed for combinatorial optimization problems that support both quantum simulators and hardware backends. Qu…
Benchmarking universal quantum gates via channel spectrum
Yanwu Gu, Wei-Feng Zhuang, Xudan Chai +1
Noise remains the major obstacle to scalable quantum computation. Quantum benchmarking provides key information on noise properties and is an important step for developing more adv…
Fast Quantum Calibration using Bayesian Optimization with State Parameter Estimator for Non-Markovian Environment
Peng Qian, Shahid Qamar, Xiao Xiao +5
As quantum systems expand in size and complexity, manual qubit characterization and gate optimization will be a non-scalable and time-consuming venture. Physical qubits have to be…
Efficient Classical Computation of Quantum Mean Values for Shallow QAOA Circuits
Wei-Feng Zhuang, Ya-Nan Pu, Hong-Ze Xu +9
The Quantum Approximate Optimization Algorithm (QAOA), which is a variational quantum algorithm, aims to give sub-optimal solutions of combinatorial optimization problems. It is wi…
