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…
Machine-learning-assisted electron-spin readout of nitrogen-vacancy center in diamond
Peng Qian, Xue Lin, Feifei Zhou +5
Machine learning is a powerful tool in finding hidden data patterns for quantum information processing. Here, we introduce this method into the optical readout of electron-spin sta…
Calibration-Free Vector Magnetometry Using Nitrogen-Vacancy Center in Diamond Integrated with Optical Vortex Beam
Bing Chen, Xianfei Hou, Feifei Ge +7
We report a new method to determine the orientation of individual nitrogen-vacancy (NV) centers in a bulk diamond and use them to realize a calibration-free vector magnetometer wit…
Digital Quantum Simulation of Floquet Topological Phases with a Solid-State Quantum Simulator
Bing Chen, Shuo Li, Xianfei Hou +6
Quantum simulator with the ability to harness the dynamics of complex quantum systems has emerged as a promising platform for probing exotic topological phases. Since the flexibili…
Detecting dynamical quantum phase transition via out-of-time-order correlations in a solid-state quantum simulator
Bing Chen, Xianfei Hou, Feifei Zhou +3
Quantum many body system in equilibrium can be effectively characterized using the framework of quantum statistical mechanics. However, nonequilibrium behaviour of quantum many bod…
A quantum algorithm for solving systems of nonlinear algebraic equations
Peng Qian, Wei-Cong Huang, Gui-Lu Long
We propose a quantum algorithm to solve systems of nonlinear algebraic equations. In the ideal case the complexity of the algorithm is linear in the number of variables , which…
