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…

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…
