Ultrafast single photon optical gating via the Kerr effect
In optical quantum communication and information protocols, it is important to have access to a high dimensional Hilbert space. The energy-time degree of freedom of photons may be used to access such a Hilbert space, as long as accurate measures of frequency and time of single photons are possible. With ultrafast timescales, it is known how to measure the phase of an electric field as a function of time, but new techniques are required for the low power, single photon regime. Optical gating is a means of using a light pulse to gate the measurement of another light pulse, and is necessary to gain timing information at ultrafast timescales. In our research, we are investigating using a nonlinear optical process called the Kerr effect to optically gate single photons for efficient ultrafast measurement. In this talk I will outline the details of our experiment as well as our current progress.
