Interference, which refers to the phenomenon associated with the superposition of waves,
has played a crucial role in the advancement of physics and finds a wide range of …

Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

Linear optics has seen a resurgence for applications in quantum information processing
owing to its miniaturisation on-chip, and increase in production efficiency and quality of …

Applications of quantum walks can depend on the number, exchange symmetry and
indistinguishability of the particles involved, and the underlying graph structures where they …

Quantum interference of two independent particles in pure quantum states is fully described
by the particles' distinguishability: the closer the particles are to being identical, the higher …

Interference between independent single photons is perhaps the most fundamental
interaction in quantum optics. It has become increasingly important as a tool for optical …

Nonclassical interference of photons lies at the heart of optical quantum information
processing. Here, we exploit tunable distinguishability to reveal the full spectrum of …

Boson sampling holds the potential to experimentally falsify the extended Church-Turing
thesis. The computational hardness of boson sampling, however, complicates the …

The collective interference of partially distinguishable bosons in multimode networks is
studied via double-sided Feynman diagrams. The probability for many-body scattering …

Boson samplers—set-ups that generate complex many-particle output states through the
transmission of elementary many-particle input states across a multitude of mutually coupled …
