Seminar

Can environmental noise enhance and sustain quantum coherence and entanglement?

Professor Eric R. Bittner
University of Houston

Generally speaking, no. However, correlation within the noise spectrum can enhance and perhaps even promote quantum coherence and entanglement between otherwise decoupled qubits. In my talk, I'll discuss a model we are developing which considers the dynamics of otherwise decoupled & localized qubits that interact via a common environment. I will discuss how correlated and anti-correlated noise can enhance fidelity of prepared Bell states, enhance (or retard) the propagation of a state along a spin chain, and perhaps lead to spontaneous synchronization of qubits.

Bio: Prof. Eric R. Bittner is a Hugh Roy and Lillie Cranz Cullen distinguished professor at the University of Houston. His research interests span a diverse range of areas within chemical physics and its interdisciplinary applications. His primary focus is on quantum dynamics and non-linear spectroscopy. He is also deeply involved in the fields of quantum optics and stochastic processes.
