Programmable sensing with quantum critical states: Trapped ion implementation

Oral-In-person  · Withdrawn

Abstract

The criticality of some quantum systems can be exploited for sensing tasks. We study first-order phase transitions of the Lipkin-Meshkov-Glick (LMG) Hamiltonian, using arrays of "all-to-all" connected qubits. In some contexts, these systems demonstrate O(10) dB of quantum gain for weak signals. We discuss the implementation of the LMG Hamiltonian on a trapped ion quantum computer, and present preliminary experimental studies of sensing parameters, such as energy threshold and lifetime, associated with these systems.
