Available student project - Developing a quantum memory for the 1550 nm optical communication band

Research fields

  • Photonics, Lasers and Nonlinear Optics
  • Quantum Devices and Technology
Magnetic rotation pattern of hyperfine transitions

Project details

Quantum memories for light are devices capable of storing and recalling the quantum state of photons. They are essential devices for optical quantum computing and optical long range quantum communication applications. We have developed quantum memories based on Pr3+ and Eu3+ ions doped in to crystals. Although these memories are state of the art they have the limitation that they operate outside the commercially important optical fibre communication band at 1550 nm. The aim of this project is to develop quantum memories with storage times in excess of a second, suitable for long range fibre communication applications. The memories will be utilizing the 1530 nm transitions in Er3+ doped crystals and our recent work in extending the spin coherence times in these materials.

Although primarily a PhD project, honours and undergraduate projects developing aspects of this experiment are also available.
