Abstract
Quantum measurement is widely used to prepare non-classical states and has important applications in quantum technologies. Here we study non-classical state preparation of a room-temperature mechanical oscillator by continuous measurement using light . We show that the experimental requirements for quantum squeezing can be relaxed in different scenarios, including in the presence of a non-Markovian thermal bath, and for a multimode oscillator. We experimentally demonstrate a thermally squeezed oscillator which is consistent with our theory, and predict that with stronger measurement we may finally achieve quantum squeezing.
About Physics Seminars
The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.
The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.
All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.
The seminars are open so there is no need to register your attendance.
