Tightening energy-based boson truncation bound using Monte Carlo-assisted methods
Jinghong Yang, Christopher F. Kane, Shabnam Jabeen
Quantum simulation offers a promising framework for quantum field theory calculations. Obtaining reliable results, however, requires careful characterization of systematic uncertai…
Obtaining continuum physics from dynamical simulations of Hamiltonian lattice gauge theories
Christopher F. Kane, Siddharth Hariprakash, Christian W. Bauer
Taking the continuum limit is essential for extracting physical observables from quantum simulations of lattice gauge theories. Achieving the correct continuum limit requires caref…
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…
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…
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…
Nearly-optimal state preparation for quantum simulations of lattice gauge theories
Christopher F. Kane, Niladri Gomes, Michael Kreshchuk
We present several improvements to the recently developed ground state preparation algorithm based on the Quantum Eigenvalue Transformation for Unitary Matrices (QETU), apply this…
Overcoming exponential volume scaling in quantum simulations of lattice gauge theories
Christopher F. Kane, Dorota M. Grabowska, Benjamin Nachman +1
Real-time evolution of quantum field theories using classical computers requires resources that scale exponentially with the number of lattice sites. Because of a fundamentally dif…
