Overview

Bowen’s research background is in quantum optics and photonics, and particularly in the important emerging fields of quantum information science and quantum opto-mechanics.

Bowen’s research background is in quantum optics and photonics, and particularly in the important emerging fields of quantum information science and quantum opto-mechanics. These fields rely critically on the development of new techniques to generate and control non-classical states of systems such as optical fields, atoms, and micromechanical cantilevers. Bowen is an internationally recognised expert in these areas. He has contributed both to the experimental demonstration of key technologies, and to the development of important new concepts, including the

*First demonstration of: a cavity opto-electromechanical system [Phys. Rev. Lett. 104 123604 (2010)], independent temperature verification in feedback cooling of a micromechanical system [Phys. Rev. Lett. 104 123604 (2010)], purification of continuous variable quantum states [Phys. Rev. Lett. 97 053601 (2006)], monolithic resonator facilitated single atom-photon interaction [Nature 443, 671 (2006)], non-trivial quantum secret sharing [Phys. Rev. Lett. 92, 177903 (2004)], photon pair generation with quantum memory capabilities [Nature 423, 731 (2003)], two dimensional sub-shot noise optical displacement measurement [Science 301, 940 (2003)], continuous variable polarisation entanglement [Phys. Rev. Lett. 89, 253601 (2002)].

*Proposal of: non-linear optics based time delayed entanglement [Phys. Rev. A Rapid 80, 010303_R (2009)], realisable technique to produce harmonic entanglement [Phys. Rev. Lett. 96, 063601 (2006) – front cover], continuous variable quantum cryptography without switching [Phys. Rev. Lett. 93, 170504 (2004)], optimal method for performing optical displacement measurements [J. Opt. B 6, 495–501 (2004)].
