Semiconductor quantum dots for optical quantum technologies
Speaker: Professor Pascale Senellart
Affiliation: The French National Centre for Scientific Research (CNRS) and the Université Paris Saclay, France
Abstract
Semiconductor quantum dots have emerged as excellent artificial atoms to both generate and manipulate quantum light. When inserted in cavities, they can generate single photons and entangled photons with unparalleled efficiency and high quantum purity. In this talk, I will discuss how acoustic phonons can be leveraged to obtain record single-photon source efficiency. This phonon-assisted excitation scheme preserve the optical selection rules and can be used to initialise and monitor the quantum state of single spins as well as to generate spin-multi-photon entanglement at high rate.
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.
