Thin-film lithium niobate two-photon and four-photon quantum sources

Thin-film lithium niobate (TFLN) has recently emerged as an ideal platform for integrated photonics owing to its broad transparency window, superior nonlinear optical characteristics, and convenience in ferroelectric domain inversion, leading to efficient quasi-phase-matched (QPM) frequency conversion processes. In par...

On-chip generation of multi-qubit graph states with high-dimensional encoded single photons

Photonic multi-qubit entanglement is key to optical quantum information processing, particularly universal quantum computing. Yet multi-photon sources suffer from low emission efficiency, making single-photon high-dimensional encoding an appealing alternative. Here we propose an explicit and resource-efficient high-dim...
