Semiconductor quantum dots (QDs) of various material systems are being heavily
researched for the development of solid state single photon emitters, which are required for …

The distribution of quantum states over long distances is limited by photon loss.
Straightforward amplification as in classical telecommunications is not an option in quantum …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

Lasers and LEDs have a statistical distribution in the number of photons emitted within a
given time interval. Applications exploiting the quantum properties of light require sources …

Single photons and entangled photon pairs are a key resource of many quantum secure
communication and quantum computation protocols, and non-Poissonian sources emitting …

At the core of an ideal single-photon detector is an active material that absorbs and converts
every incident photon to a discriminable signal. A large active material favours efficient …

Long-distance quantum communication relies on the ability to efficiently generate and
prepare single photons at telecom wavelengths. In many applications these photons must …

Transducing non-classical states of light from one wavelength to another is required for
integrating disparate quantum systems that take advantage of telecommunications-band …

We present an efficient architecture for quantum repeaters based on single-photon sources
in combination with quantum memories for photons. Errors inherent to previous repeater …
