Frequency Conversion and Time Reversal of Single-Photon States for a Quantum Internet

Speaker:  Mike Raymer, UO

Abstract: Given a single photon, information can be encoded on it using its color (frequency) or temporal shape (temporal mode). Nonlinear wave mixing in a strongly driven medium can exchange (or swap) the quantum states between two narrow spectral bands of the optical spectrum. When one spectral band is occupied by a single-photon wave-packet state, and the other band is occupied by vacuum, this process can achieve quantum frequency conversion (QFC), changing the carrier frequency of the photon. QFC can also act to time reverse the photon’s wave packet. Both of these operations play essential roles in creating a future quantum Internet.
