Entangled photon sources are desirable and key elements for photonic quantum information
processing. The spontaneous parametric down‐conversion (SPDC) process is a convenient …

The violation of a Bell inequality is an experimental observation that forces the
abandonment of a local realistic viewpoint—namely, one in which physical properties are …

Semiconductor quantum dots in cavities are promising single-photon sources. Here, we
present a path to deterministic operation, by harnessing the intrinsic linear dipole in a …

Entangled photon pairs are a critical resource in quantum communication protocols ranging
from quantum key distribution to teleportation. The current workhorse technique for …

The development of large-scale optical quantum information processing circuits ground on
the stability and reconfigurability enabled by integrated photonics. We demonstrate a …

We generate pulsed, two-mode squeezed states in a single spatiotemporal mode with mean
photon numbers up to 20. We directly measure photon-number correlations between the two …

Parametric single-photon sources are well suited for large-scale quantum networks due to
their potential for photonic integration. Active multiplexing of photons can overcome the …

Quantum teleportation is an essential quantum operation by which we can transfer an
unknown quantum state to a remote location with the help of quantum entanglement and …

Abstract Quantum Information Networks (QINs) attract increasing interest, as they enable
connecting quantum devices over long distances, thus greatly enhancing their intrinsic …

It is well known that an unambiguous discrimination of the four optically encoded Bell states
is possible with a probability of 50% at best, when using static, passive linear optics and …
