First-ever calculation performed on optical quantum computer chip

(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed ...

Quantum teleportation on a chip

The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, ...

What if we could teach photons to behave like electrons?

To develop futuristic technologies like quantum computers, scientists will need to find ways to control photons, the basic particles of light, just as precisely as they can already control electrons, the basic particles in ...

Time Lens Speeds Up Optical Data Transmission

(PhysOrg.com) -- Researchers at Cornell University have developed a device called a "time lens" which is a silicon device for speeding up optical data. The basic components of this device are an optical-fiber coil, laser, ...

Engineering researchers produce breakthrough for photography

A revolutionary breakthrough is underway at Dartmouth's Thayer School of Engineering, an innovation that may usher in the next generation of light sensing technology with potential applications in scientific research and ...

Pristine quantum light source created at the edge of silicon chip

The smallest amount of light you can have is one photon, so dim that it's pretty much invisible to humans. While imperceptible, these tiny blips of energy are useful for carrying quantum information around. Ideally, every ...
