There has been significant experimental progress in encoding and manipulating quantum information using light’s spectral-temporal degrees of freedom. From electro-optics to nonlinear optics – a range of technologies has been utilized to prepare, control, and characterize qubits and demonstrate quantum logic. Spectral encoding is naturally compatible with optical fiber networks, amenable to massive parallelization, and valuable for scaling up quantum memories. Spectral beam splitters, based both on optical nonlinearities and electro-optic modulation, have been demonstrated recently. For spectral-temporal encoding, which can be used to store large amounts of information in a single photon, quantum pulse gates based on mixing single photons with shaped control fields have allowed state discrimination of orthogonal time-frequency pulsed modes (temporal modes). Considerable advances have also been made in generating entangled frequency combs from bulk sources and on-chip by using microring resonators, opening new avenues for quantum information processing with qudits. These novel techniques and methods can be combined and readily utilized for applications in quantum networking, computing, key distribution, and classical optical information processing. The aim of this symposium is to bring together researchers from across these research fields and to expose others to the exciting new opportunities offered by spectral-temporal encoding of light.
