Block encoding bosons by signal processing
Christopher F. Kane, Siddharth Hariprakash, Neel S. Modi +2
Block Encoding (BE) is a crucial subroutine in many modern quantum algorithms, including those with near-optimal scaling for simulating quantum many-body systems, which often rely…

A Fully Gauge-Fixed SU(2) Hamiltonian for Quantum Simulations
Dorota M. Grabowska, Christopher F. Kane, Christian W. Bauer
We demonstrate how to construct a fully gauge-fixed lattice Hamiltonian for a pure SU(2) gauge theory. Our work extends upon previous work, where a formulation of an SU(2) lattice…

Strategies for simulating time evolution of Hamiltonian lattice field theories
Siddharth Hariprakash, Neel S. Modi, Michael Kreshchuk +2
Simulating the time evolution of quantum field theories given some Hamiltonian requires developing algorithms for implementing the unitary operator e^{-iHt}. A variety of techn…
