Time-bin-to-polarization conversion of ultrafast photonic qubits. Kupchak, C., Bustard, P., Heshami, K., Erskine, J., Spanner, M., England, D., & Sussman, B.

Paper doi abstract bibtex The encoding of quantum information in photonic time-bin qubits is apt for long-distance quantum communication schemes. In practice, due to technical constraints such as detector response time, or the speed with which copolarized time-bins can be switched, other encodings, e.g., polarization, are often preferred for operations like state detection. Here, we present the conversion of qubits between polarization and time-bin encodings by using a method that is based on an ultrafast optical Kerr shutter and attain efficiencies of 97% and an average fidelity of 0.827$±$0.003 with shutter speeds near 1 ps. Our demonstration delineates an essential requirement for the development of hybrid and high-rate optical quantum networks. © 2017 American Physical Society.
