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 …

A single photon can be coupled to collective charge oscillations at the interfaces between
metals and dielectrics forming a single surface plasmon. The electromagnetic near-fields …

We study the simultaneous estimation of multiple phases as a discretized model for the
imaging of a phase object. We identify quantum probe states that provide an enhancement …

The identification of phenomena able to pinpoint quantum interference is attracting large
interest. Indeed, a generalization of the Hong–Ou–Mandel effect valid for any number of …

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

We discuss recent research on quantum transport in complex materials, from photosynthetic
light-harvesting complexes to photonic circuits. We identify finite, disordered networks as 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 …

We generalize an approach for description of multiphoton experiments with multiport unitary
linear optical devices, started in Phys. Rev. A 89, 022333 (2014) PLRAAN 1050-2947 …

Graph representations are a powerful concept for solving complex problems across natural
science, as patterns of connectivity can give rise to a multitude of emergent phenomena …
