The NV center in diamond: a versatile quantum technology

Colloquium: Ania Jayich, University of California, Santa Barbara

The nitrogen vacancy (NV) center in diamond is an atomic-­scale defect that exhibits remarkably coherent quantum properties in a uniquely accessible way: at room temperature, in ambient conditions, and even immersed in biological environments. NV centers are being explored for a variety of quantum technologies, including quantum sensing and quantum information processing.

Quantum clocks and information driven heat engines

Seminar: Bhaskaran Muralidharan

We describe two distinct applications of quantum dots [1-3] from a quantum transport perspective. In the first part, we bring in a Bayesian viewpoint to the analysis of clocks, specifically taking the Salecker Wigner clock formulation [4] and explore a novel set up to estimate the tunneling time [1] between electrons in a contact and a quantum dot weakly coupled to it. Using the exponential tunneling distribution as priors for clocks, we analyze the case of a single precessing spin in a quantum dot.
