A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of ...

Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Quantum technologies are systems that can compute data, sense their surrounding environment or perform other functions leveraging quantum mechanical effects. Connecting these technologies over long ...

Researchers at the University of Rochester and Rochester Institute of Technology recently connected their campuses with an experimental quantum communications network using two optical fibers. In a ...

Researchers at The Grainger College of Engineering are using atom-photon entanglement to work towards the future of quantum ...

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...

Controlling light at the level of individual photons could one day do for quantum networks what switching and routing have done for classical internet infrastructure. To help realize that vision, ...

Kyoto, Japan -- The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each ...

A team of researchers in China claims to have made the first conclusive demonstration of ‘quantum advantage’ – using quantum mechanics to perform calculations that would be too slow on classical ...
