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 …

Complex forms of quantum entanglement can arise in two qualitatively different ways: either
between many qubits or between two particles with higher-than-qubit dimension. While both …

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 develo** 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 …

Quantum computers can revolutionize science and technology, but their realization remains
challenging across all platforms. A promising route to scalability is photonic-measurement …

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