Quantum Simulation of Boson-Related Hamiltonians: Techniques, Effective Hamiltonian Construction, and Error Analysis
Bo Peng, Yuan Su, Daniel Claudino +3
A broad spectrum of physical systems in condensed-matter and high-energy physics, vibrational spectroscopy, and circuit and cavity QED necessitates the incorporation of bosonic deg…
Impact of high-rank excitations on accuracy of the unitary coupled cluster downfolding formalism
Karol Kowalski, Bo Peng, Nicholas P. Bauman
In this paper, we evaluate the accuracy of the Hermitian form of the downfolding procedure utilizing the double unitary coupled cluster Ansatz (DUCC) on the H6 and H8 benchmark sys…
Quantum flow algorithms for simulating many-body systems on quantum computers
Karol Kowalski, Nicholas P. Bauman
We conducted quantum simulations of strongly correlated systems using the quantum flow (QFlow) approach, which enables sampling large sub-spaces of the Hilbert space through couple…
Coupled cluster downfolding techniques: a review of existing applications in classical and quantum computing for chemical systems
Nicholas P. Bauman, Bo Peng, Karol Kowalski
In this manuscript, we provide an overview of the recent developments of the coupled cluster (CC) downfolding methods, where the ground-state problem of a quantum system is represe…
Quantum algorithms for generator coordinate methods
Muqing Zheng, Bo Peng, Nathan Wiebe +3
This paper discusses quantum algorithms for the generator coordinate method (GCM) that can be used to benchmark molecular systems. The GCM formalism defined by exponential operator…
Fock-space Schrieffer--Wolff transformation: classically-assisted rank-reduced quantum phase estimation algorithm
Karol Kowalski, Nicholas P. Bauman
We present an extension of many-body downfolding methods to reduce the resources required in the quantum phase estimation (QPE) algorithm. In this paper, we focus on the Schrieffer…
