In this talk, I present an experimental realization of a quantum absorption refrigerator formed from superconducting circuits. The refrigerator is used to reset a transmon qubit to a temperature lower than that achievable with any one available bath. The process is driven by a thermal gradient and is autonomous -- requires no external control. The refrigerator exploits an engineered three-body interaction between the target qubit and two auxiliary qudits coupled to thermal environments, formed from microwave waveguides populated with thermal photons.

In this seminar, we are interested in all aspects of research at the intersection between quantum information science and mathematics. Goals for the seminar include:

Universal behaviors of nonequilibrium quantum many-body systems may be usefully captured by the dynamics of quantum information measures. Notably, the dynamics of bipartite entanglement entropy can distinguish integrable quantum systems from chaotic ones. The two most successful effective theories describing the evolution of entanglement from a low-entangled initial state are the quasiparticle picture and the membrane picture, which provide distinct predictions for integrable and chaotic systems, respectively.

Aleksander Kubica, Assistant Professor at Yale University and former Research Scientist at AWS will give a career talk on his experiences in both industry and academia, present a short lecture on quantum chess, and take questions from the audience.  

A key objective in nuclear and high-energy physics is to describe nonequilibrium dynamics of matter, e.g., in the early universe and in particle colliders, starting from the Standard Model. Classical-computing methods, via the framework of lattice gauge theory, have experienced limited success in this mission. Quantum simulation of lattice gauge theories holds promise for overcoming computational limitations. Because of local constraints (Gauss's laws), lattice gauge theories have an intricate Hilbert-space structure.

In this Career Connections talk, Dr. Mihir Bhaskar (CEO and Co-Founder of Lightsynq) will share insights from his career journey: first building a science experiment in the lab as a PhD student, then moving to AWS to launch a new R&D initiative, and finally starting a quantum technology company to build a product. He will also talk about the integrated photonic capabilities his team has developed along the way, and how he thinks they can solve key bottlenecks in quantum information technology.
