Quantum Photonics Laboratory
We explore the spectral-temporal properties of single photon pulses and their use as quantum information carriers. We combine methods of quantum optics, femtosecond pulse and nonlinear optics, temporal Fourier optics, electro-optics and high-frequency electronics to experimentally investigate coherent modification of spectral-temporal mode structure of quantum light. We explore photonic time-energy entanglement. Our results lead to photonic interfaces for quantum internet, quantum gates for time-frequency encoding and efficient quantum cryptography protocols.
