​When: April 7, 4:15–5:15 pm 

​Where: Lauritsen 269, Caltech

​Talk: Measurement-altered quantum matter

​​Abstract: In the study of quantum matter, measurements have traditionally been viewed as a means of learning about a system. Measurements can, nevertheless, play a more active role, generating novel quantum phenomena that may be difficult or impossible to realize in measurement-free settings. As an interesting example, I will discuss how measurements can dramatically alter universal properties of quantum systems tuned to a phase transition. I will also highlight a path to experimental realization in analog quantum simulators based on Rydberg atom arrays. Finally, I will describe how these ideas inform optimization of quantum teleportation protocols against imperfections, establishing a long-term quantum science application of ‘measurement-altered quantum criticality’.

Bio: Jason Alicea is a theoretical physicist and professor at Caltech whose research focuses on quantum many-body systems, topological phases of matter, and quantum information. His work often explores exotic quantum phenomena with potential applications in quantum computing, including Majorana modes and non-equilibrium quantum dynamics. He is also affiliated with Caltech’s Institute for Quantum Information and Matter.
