Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

Structured light has become topical of late, where controlling light in all its degrees of
freedom has offered novel states of light long predicted, enhanced functionality in …

Quantum teleportation provides a way to transmit unknown quantum states from one
location to another. In the quantum world, multilevel systems which enable high-dimensional …

The transfer of quantum information through a noisy environment is a central challenge in
the fields of quantum communication, imaging and nanophotonics. In particular, high …

Programmable optical circuits are an important tool in developing quantum technologies
such as transceivers for quantum communication and integrated photonic chips for quantum …

A primary requirement for a robust and unconditionally secure quantum network is the
establishment of quantum nonlocal correlations over a realistic channel. While loophole-free …

Spatial correlations between two photons are the key resource in realising many quantum
imaging schemes. Measurement of the bi-photon correlation map is typically performed …

High-dimensional quantum entanglement can give rise to stronger forms of nonlocal
correlations compared to qubit systems, offering significant advantages for quantum …

We introduce two families of criteria for detecting and quantifying the entanglement of a
bipartite quantum state of arbitrary local dimension. The first is based on measurements in …

Two-photon Hong-Ou-Mandel (HOM) interference is a fundamental quantum effect with no
classical counterpart. The existing research on two-photon interference was mainly limited in …
