Condensed Matter Seminar: Quantum technologies based on open quantum systems

Abstract:

Studies of technologies based on quantum systems have gained immense importance in recent years, owing to the current experimental progress in control of quantum systems. I will talk about technologies based on open quantum systems. I will show how efficiencies of quantum heat engines powered by squeezed thermal reservoirs can surpass the Carnot limit, without violating the second law of thermodynamics. I will also talk about dynamical control of quantum systems, which can lead to quantum advantage in heat machines, as well as enable us to perform high-precision low-temperature thermometry close to the absolute zero.
