Hierarchical Equations of Motion Solved with the Multiconfigurational Ehrenfest Ansatz
Zhecun Shi, Huiqiang Zhou, Lei Huang +2
Being a numerically exact method for the simulation of dynamics in open quantum systems, the hierarchical equations of motion (HEOM) still suffers from the curse of dimensionality.…
Variational Quantum Metrology with Loschmidt Echo
Ran Liu, Ze Wu, Xiaodong Yang +6
By utilizing quantum mechanical effects, such as superposition and entanglement, quantum metrology promises higher precision than the classical strategies. It is, however, practica…
Optimal and robust experiment design for quantum state tomography of star-topology register
Ran Liu, Yanjun Hou, Ze Wu +5
While quantum state tomography plays a vital role in the verification and benchmarking of quantum systems, it is an intractable task if the controllability and measurement of quant…
Preparing Greenberger-Horne-Zeilinger and states on a long-range Ising spin model by global controls
Jiahui Chen, Hui Zhou, Changkui Duan +1
Entanglement, a unique quantum resource with no classical counterpart, remains at the heart of quantum information. The Greenberger-Horne-Zeilinger (GHZ) and states are two ine…
Pure State Tomography with Pauli Measurements
Xian Ma, Tyler Jackson, Hui Zhou +10
We examine the problem of finding the minimum number of Pauli measurements needed to uniquely determine an arbitrary -qubit pure state among all quantum states. We show that onl…
Observation of Lee-Yang zeros
Xinhua Peng, Hui Zhou, Bo-Bo Wei +3
Lee-Yang zeros are points on the complex plane of magnetic field where the partition function of a spin system is zero and therefore the free energy diverges. Lee-Yang zeros and th…
