Quantum 2.0 Conference and Exhibition.
We experimentally demonstrate multi-order quasi-phase-matching conditions for spectral shaping of photon pairs produced by spontaneous parametric downconversion. Incorporated with a group-velocity matching condition, our multi-order quasi-phase-match

Photon-pair generation via spontaneous parametric downconversion (SPDC) has been widely used for optical quantum information experiments. We demonstrate high-precision spectral measurements of SPDC sources, utilizing frequency-resolved sum-frequency

Tailoring spectral properties of photon pairs is of great importance for optical quantum information and measurement applications. High-resolution spectral measurement is a key technique for engineering spectral properties of photons, making them ide

Quantum information processing with photons can be greatly enhanced by incorporating time-multiplexing methods. Not only can time-bin encoding be very useful in its own right, multiplexing techniques can lead to more efficient single- and multi-photo

We report a simple scheme for direct generation of frequency-bin entangled photon pairs via spontaneous parametric downconversion. Our fabricated nonlinear optical crystal with two different poling periods can simultaneously satisfy two different, sp

Very efficient sources of pure single photons can be realized by combining optimized, heralded nondeterministic photon sources with spatial or temporal multiplexing. Low-loss synchronization elements can further enhance scalability, enabling various

We demonstrate relative time multiplexing of heralded single-photon sources, using a low-loss photon storage technique. Our scheme can realize efficient two-photon quantum communication protocols, e.g., measurement-device-independent quantum key dist
