Toward Quantum Simulations of Gauge Theory Without State Preparation
Erik J. Gustafson, Henry Lamm
Preparing strongly-coupled particle states on quantum computers requires large resources. In this work, we show how classical sampling coupled with projection operators can be used…
Suppressing Coherent Gauge Drift in Quantum Simulations
Henry Lamm, Scott Lawrence, Yukari Yamauchi
Simulations of field theories on noisy quantum computers must contend with errors introduced by that noise. For gauge theories, a large class of errors violate gauge symmetry, and…
Gluon Field Digitization via Group Space Decimation for Quantum Computers
Yao Ji, Henry Lamm, Shuchen Zhu
Efficient digitization is required for quantum simulations of gauge theories. Schemes based on discrete subgroups use fewer qubits at the cost of systematic errors. We systematize…
Quantum Simulation of Field Theories Without State Preparation
Siddhartha Harmalkar, Henry Lamm, Scott Lawrence
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…
Nucleon form factors from basis light front quantization
Chandan Mondal, Siqi Xu, Jiangshan Lan +4
We investigate the electromagnetic form factors of the nucleon in the framework of basis light front quantization. We compute the form factors using the light front wavefunctions o…
