Joint Quantum Seminar Wednesday, September 11 4:00 PM, Jefferson 250 Prof. Markus Aspelmeyer University of Vienna Institute for Quantum Optics and Quantum Information (IQOQI) , Austrian Academy of Sciences “Quantum Optical Control of Levitated Solids: a novel probe for the gravity-quantum interface” The increasing level of control over motional quantum states of massive, solid-state mechanical devices opens the door to an hitherto unexplored parameter regime of macroscopic quantum physics. I will report on our recent progress towards controlling levitated solids in the quantum regime. I will discuss the prospects of using these systems for fundamental tests of physics, including the interface between quantum and gravitational physics. 4:00 pm: 10-minute Talk 4:10 pm: Refreshments 4:30 pm: Prof. Aspelmeyer -- Clare Ploucha Director of Programs Harvard Quantum Initiative 17 Oxford Street, Jefferson 357 Cambridge, MA 02138 P: 617-495-3388
