Quantum Simulation of Field Theories Without State Preparation

2020 · arXiv (Cornell University)

We propose an algorithm for computing real-time observables using a quantum processor while avoiding the need to prepare the full quantum state. This reduction in quantum resources is achieved by classically sampling configurations in imaginary-time …

Improved Hamiltonians for Quantum Simulations of Gauge Theories

2022 · Physical Review Letters

Quantum simulations of lattice gauge theories for the foreseeable future will be hampered by limited resources. The historical success of improved lattice actions in classical simulations strongly suggests that Hamiltonians with improved discretization errors will …
