Truncation uncertainties for accurate quantum simulations of lattice gauge theories
Anthony N. Ciavarella, Siddharth Hariprakash, Jad C. Halimeh +1
The encoding of lattice gauge theories onto quantum computers requires a discretization of the gauge field's Hilbert space on each link, which presents errors with respect to the K…
The Practicality of Randomized Quantum Linear Systems Solvers
Siddharth Hariprakash, Roel Van Beeumen, Katherine Klymko +1
Randomized quantum algorithms have been proposed for quantum linear algebra with the goal of constructing shallower circuits than methods based on block encodings, and have been sp…
A Practical Guide to using Pauli Path Simulators for Utility-Scale Quantum Experiments
Hrant Gharibyan, Siddharth Hariprakash, Mohammed Zuhair Mullath +1
In this this paper we present an inexpensive protocol to perform runtime and memory estimation for large-scale experiments with Pauli Path simulators (PPS). Additionally, we propos…
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…
