THz-bandwidth all-optical switching of heralded single photons
Connor Kupchak, Jennifer Erskine, Duncan G. England +1
Optically induced ultrafast switching of single photons is demonstrated by rotating the photon polarization via the Kerr effect in a commercially available single mode fiber. A swi…
Time-bin to Polarization Conversion of Ultrafast Photonic Qubits
Connor Kupchak, Philip J. Bustard, Khabat Heshami +4
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 r…
Ultra-low-noise room-temperature quantum memory for polarization qubits
Mehdi Namazi, Connor Kupchak, Bertus Jordaan +2
Here we show an ultra-low noise regime of operation in a simple quantum memory in warm Rb atomic vapor. By modelling the quantum dynamics of four-level room temperature atoms, we a…
Quantum Process Tomography of an Optically-Controlled Kerr Non-linearity
Connor Kupchak, Samuel Rind, Bertus Jordaan +1
Any optical quantum information processing machine would be comprised of fully-characterized constituent devices for both single state manipulations and tasks involving the interac…
Cascading Quantum Light-Matter Interfaces
Mehdi Namazi, Thomas Mittiga, Connor Kupchak +1
The ability to interface multiple optical quantum devices is a key milestone towards the development of future quantum networks that are capable of sharing and processing quantum i…
Room-Temperature Quantum Memory for Polarization States
Connor Kupchak, Thomas Mittiga, Bertus Jordaan +3
An optical quantum memory is a stationary device that is capable of storing and recreating photonic qubits with a higher fidelity than any classical device. Thus far, these two req…
