Keldysh Nonlinear Sigma Model for a Free-Fermion Gas under Continuous Measurements
Qinghong Yang, Yi Zuo, Dong E. Liu
Quantum entanglement phase transitions have provided new insights to quantum many-body dynamics. Both disorders and measurements are found to induce similar entanglement transition…
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…
Quantum circuit architecture search on a superconducting processor
Kehuan Linghu, Yang Qian, Ruixia Wang +14
Variational quantum algorithms (VQAs) have shown strong evidences to gain provable computational advantages for diverse fields such as finance, machine learning, and chemistry. How…
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…
An analytic study of the independent coherent errors in the surface code
Yuanchen Zhao, Dong E. Liu
The realistic coherent errors could induce very different behaviors compared with their stochastic counterparts in the quantum error correction (QEC) and fault tolerant quantum com…
Effect of quantum error correction on detection-induced coherent errors
Qinghong Yang, Dong E. Liu
We study the performance of quantum error correction codes (QECCs) under the detection-induced coherent error due to the imperfectness of practical implementations of stabilizer me…
