Learning Quantum Hamiltonians from Single-qubit Measurements
Liangyu Che, Chao Wei, Yulei Huang +6
It is natural to measure the observables from the Hamiltonian-based quantum dynamics, and its inverse process that Hamiltonians are estimated from the measured data also is a vital…
Hybrid quantum-classical approach to enhanced quantum metrology
Xiaodong Yang, Xi Chen, Jun Li +2
Quantum metrology plays a fundamental role in many scientific areas. However, the complexity of engineering entangled probes and the external noise raise technological barriers for…
Optimizing adiabatic quantum pathways via a learning algorithm
Xiaodong Yang, Ran Liu, Jun Li +1
Designing proper time-dependent control fields for slowly varying the system to the ground state that encodes the problem solution is crucial for adiabatic quantum computation. How…
Dynamical-Invariant-based Holonomic Quantum Gates: Theory and Experiment
Yingcheng Li, Tao Xin, Chudan Qiu +5
Among existing approaches to holonomic quantum computing, the adiabatic holonomic quantum gates (HQGs) suffer errors due to decoherence, while the non-adiabatic HQGs either require…
Quantum Pure State Tomography via Variational Hybrid Quantum-Classical Method
Tao Xin, Xinfang Nie, Xiangyu Kong +3
To obtain a complete description of a quantum system, one usually employs standard quantum state tomography, which however requires exponential number of measurements to perform an…
Experimental Detection of the Quantum Phases of a Three-Dimensional Topological Insulator on a Spin Quantum Simulator
Tao Xin, Yishan Li, Yu-ang Fan +6
The detection of topological phases of matter becomes a central issue in recent years. Conventionally, the realization of a specific topological phase in condensed matter physics r…
