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 ...

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ...

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

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 ...

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 ...

Sparrow Quantum, a Copenhagen-based startup specializing in single-photon emitters suitable for a range of quantum technology applications, has raised €21.5 million in a series A funding round. Led by ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
