Epitaxial quantum dots formed by III–V compound semiconductors are excellent sources of
non-classical photons, creating single photons and entangled multi-photon states on …

Realizing a sensitive photon-number-dependent phase shift on a light beam is required both
in classical and quantum photonics. It may lead to new applications for classical and …

In the framework of optical quantum computing and communications, a major objective
consists in building receiving nodes implementing conditional operations on incoming …

A quantum emitter interacting with photons in a single optical-mode constitutes a one-
dimensional atom. A coherent and efficiently coupled one-dimensional atom provides a …

Efficient and tunable qubit unidirectional routers and spin-wave diodes play an important
role in classical and quantum information processing domains. Here we reveal that …

Irreversible logic is at odds with unitary quantum evolution. Emulating such operations by
classical measurements can result in disturbances and high resource demands. To …

Based on the broken spatial symmetry, we propose a scheme for engineering a
unidirectional photonic reflector using a one-dimensional atomic lattice with defective cells …

Realizing a sensitive photon-number-dependent phase shift on a light beam is required both
in classical and quantum photonics. It may lead to new applications for classical and …

The development of an interface between stationary qubits and messenger qubits offers
many possibilities for quantum communications, via the exchange of information between …

Nonreciprocal optical devices (NROD) working in the quantum regime are the key building
blocks for nonreciprocal quantum information processing. Conventional NRODs require a …
