Ion Trap Quatnum Simulators for Spin-Boson Models
ORAL · Invited
Abstract
Spin-boson models are common throughout physics. Trapper ion quantum computers are built off internal degrees of freedom in the ions (qubits) and external degrees of freedom (phonons). For quantum computation, the phonons are used as an information bus for generating entanglement between qubits, but are not used to store quantum information. We have recently used the spin and motional modes to perform quantum simulations of molecular dynamics of conical intersections and vibrational energy transfer with structured baths. After describing these results, I will discuss how these methods can be extended to other chemical dynamics simulations and the simulation of nuclear physics.
