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

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 …

It is well known that photons can carry a spatial structure akin to a'twisted'or'rippled'
wavefront. Such structured light fields have sparked significant interest in both classical and …

High-dimensional entanglement offers a variety of advantages for both fundamental and
applied applications in quantum information science. A central building block for such …

Spontaneous parametric down-conversion (SPDC) is a widely used source for photonic
entanglement. Years of focused research have led to a solid understanding of the process …

Simulators can realise novel phenomena by separating them from the complexities of a full
physical implementation. Here we put forward a scheme that can simulate the exotic …

We introduce a noise-robust and loss-tolerant test of quantum steering designed for single-
detector measurements that harnesses the advantages of high-dimensional entanglement …

We present analytic expressions for the coincidence detection probability amplitudes of
photon pairs generated by spontaneous parametric down-conversion in both momentum …

Programmable optical circuits form a key part of quantum technologies today. As the size of
such circuits is increased, maintaining precise control over every individual component …
