Quantum Simulation of Bosons with the Contracted Quantum Eigensolver
Yuchen Wang, LeeAnn M. Sager-Smith, David A. Mazziotti
Quantum computers are promising tools for simulating many-body quantum systems due to their potential scaling advantage over classical computers. While significant effort has been…
Mapping Molecular Hamiltonians into Hamiltonians of Modular cQED Processors
Ningyi Lyu, Alessandro Miano, Ioannis Tsioutsios +7
We introduce a general method based on the operators of the Dyson-Masleev transformation to map the Hamiltonian of an arbitrary model system into the Hamiltonian of a circuit Quant…
Electronic Excited States from a Variance-Based Contracted Quantum Eigensolver
Yuchen Wang, David A. Mazziotti
Electronic excited states of molecules are central to many physical and chemical processes, and yet they are typically more difficult to compute than ground states. In this paper w…
Quantum Simulation of the Radical Pair Dynamics of the Avian Compass
Yiteng Zhang, Zixuan Hu, Yuchen Wang +1
The simulation of open quantum dynamics on quantum circuits has attracted wide interests recently with a variety of quantum algorithms developed and demonstrated. Among these, one…
Simulating Open Quantum System Dynamics on NISQ Computers with Generalized Quantum Master Equations
Yuchen Wang, Ellen Mulvihill, Zixuan Hu +7
We present a quantum algorithm based on the Generalized Quantum Master Equation (GQME) approach to simulate open quantum system dynamics on noisy intermediate-scale quantum (NISQ)…
Multiplicity of non-contractible closed geodesics on Finsler compact space forms
Hui Liu, Yuchen Wang
Let and be a nontrivial element of finite order in , where the integer , is a finite abelian group which acts freely and isometrically on…
Statistical Approach to Quantum Phase Estimation
Alexandria J. Moore, Yuchen Wang, Zixuan Hu +2
We introduce a new statistical and variational approach to the phase estimation algorithm (PEA). Unlike the traditional and iterative PEAs which return only an eigenphase estimate,…
Qudits and high-dimensional quantum computing
Yuchen Wang, Zixuan Hu, Barry C. Sanders +1
Qudit is a multi-level computational unit alternative to the conventional 2-level qubit. Compared to qubit, qudit provides a larger state space to store and process information, an…
Quantum Phase Estimation with Time-Frequency Qudits in a Single Photon
Hsuan-Hao Lu, Zixuan Hu, Mohammed S. Alshaykh +5
The Phase Estimation Algorithm (PEA) is an important quantum algorithm used independently or as a key subroutine in other quantum algorithms. Currently most implementations of the…
Concentrated steady vorticities of the Euler equation on 2-d domains and their linear stability
Yiming Long, Yuchen Wang, Chongchun Zeng
We consider concentrated vorticities for the Euler equation on a smooth domain in the form of \[ ω= \sum_{j=1}^N ω_j χ_{Ω_j}, \quad |Ω_j| = πr_j^2, \quad \i…
