Development of a Room Temperature Optical Quantum Memory

Lead Research Organisation: University College London
Department Name: London Centre for Nanotechnology


Within photonic based quantum technologies one of the most critical components identified is a quantum memory; a device which can store and retrieve an arbitrary quantum state at the single photon level. The development of such a memory would allow the creation of a vast number of quantum technologies ranging from the ability to synchronise processing steps in an optical based quantum computer, to the construction of a quantum repeater which would allow for perfect transmission of quantum states over arbitrary distances. My project will investigate the development and applications of a quantum memory based on a 3 level A-system using Raman scattering. The Raman memory is a single-mode memory that can selectively store a user-chosen temporal mode that is, a temporal pulse shape of a single photon. Temporal modes have been identified as promising basis states for quantum information processing, making the Raman memory an even more promising tool for future applications.
