Unruh-DeWitt Quantum Computing: Realizing Quantum Shannon Theory With Quantum Fields
Eric W. Aspling
Qubit-field quantum transduction provides numerous advantages to quantum computing, such as device-specific error-correcting codes, efficient scalability, and effective entanglemen…
Universal Quantum Computing with Field-Mediated Unruh--DeWitt Qubits
Eric Aspling, Michael Lawler
A set of universal quantum gates is a vital part of the theory of quantum computing, but is absent in the developing theory of Relativistic Quantum Information (RQI). Yet, the Unru…
High Capacity Noisy Unruh--DeWitt Quantum Channels with Bosonic Dephasing
Eric Aspling, Michael Lawler
Unruh--DeWitt (UDW) detectors implemented as UDW quantum gates provide a framework for evaluating quantum Shannon theory properties of qubit-field systems. UDW quantum channels con…
Revealing microcanonical phases and phase transitions of strongly correlated electrons via time-averaged classical shadows
Gaurav Gyawali, Mabrur Ahmed, Eric Aspling +2
Quantum computers and simulators promise to enable the study of strongly correlated quantum systems. Yet, surprisingly, it is hard for them to compute ground states. They can, howe…
Design Constraints for Unruh-DeWitt Quantum Computers
Eric W. Aspling, John A. Marohn, Michael J. Lawler
The Unruh-DeWitt particle detector model has found success in demonstrating quantum information channels with non-zero channel capacity between qubits and quantum fields. These det…
