The optical fibre is an essential tool for our communication infrastructure since it is the main transmission channel for optical communications. The latest major advance in optical fibre …
The transverse spatial effects observed in photon pairs produced by parametric down- conversion provide a robust and fertile testing ground for studies of quantum mechanics …
We present a protocol for large-alphabet quantum key distribution (QKD) using energy-time entangled biphotons. Binned, high-resolution timing measurements are used to generate a …
We present a proof of principle demonstration of a quantum key distribution scheme in higher-order d-dimensional alphabets using spatial degrees of freedom of photons. Our …
Multiplexing is a strategy to augment the transmission capacity of a communication system. It consists of combining multiple signals over the same data channel and it has been very …
