Variational quantum eigensolvers for sparse Hamiltonians
William M. Kirby, Peter J. Love
Hybrid quantum-classical variational algorithms such as the variational quantum eigensolver (VQE) and the quantum approximate optimization algorithm (QAOA) are promising applicatio…
Simulating Hadronic Physics on NISQ devices using Basis Light-Front Quantization
Michael Kreshchuk, Shaoyang Jia, William M. Kirby +3
The analogy between quantum chemistry and light-front quantum field theory, first noted by Kenneth G. Wilson, serves as motivation to develop light-front quantum simulation of quan…
Consistency testing for robust phase estimation
Antonio E. Russo, William M. Kirby, Kenneth M. Rudinger +2
We present an extension to the robust phase estimation protocol, which can identify incorrect results that would otherwise lie outside the expected statistical range. Robust phase…
Contextual Subspace Variational Quantum Eigensolver
William M. Kirby, Andrew Tranter, Peter J. Love
We describe the contextual subspace variational quantum eigensolver (CS-VQE), a hybrid quantum-classical algorithm for approximating the ground state energy of a Hamiltonian. The a…
Light-Front Field Theory on Current Quantum Computers
Michael Kreshchuk, Shaoyang Jia, William M. Kirby +3
We present a quantum algorithm for simulation of quantum field theory in the light-front formulation and demonstrate how existing quantum devices can be used to study the structure…
Classical Simulation of Noncontextual Pauli Hamiltonians
William M. Kirby, Peter J. Love
Noncontextual Pauli Hamiltonians decompose into sets of Pauli terms to which joint values may be assigned without contradiction. We construct a quasi-quantized model for noncontext…
Quantum Simulation of Quantum Field Theory in the Light-Front Formulation
Michael Kreshchuk, William M. Kirby, Gary Goldstein +2
Quantum chromodynamics (QCD) describes the structure of hadrons such as the proton at a fundamental level. The precision of calculations in QCD limits the precision of the values o…
