Michael Sprague

DPhil Student and Clarendon Scholar

My research centres on building a quantum memory for applications in secure communication, quantum computation and tests of fundamental physics. Specifically, I work on realising a broadband, room-temperature memory using optical phonons in diamond and using a thermal vapour of cesium. I work in the Ultrafast quantum optics and optical metrology group led by Prof. Ian Walmsley. My research is supported by a Clarendon Fund Scholarship and a St. Edmund Hall Graduate Scholarship.

I am originally from Toronto, Canada and I attended high school in Warsaw, Poland. I studied Engineering Physics at Queen's University, Canada as an undergraduate, and obtained my Master's from the University of Toronto, where I studied correlated, 'many-body' physics using ultracold atoms. I enjoy playing volleyball, squash, and tennis (albeit with less success). I am also keen on sailing, butterflies (esp. Birdwings and Swallowtails), and the work of Vladimir Nabokov.
