Researchers at CRANN and the School of Physics at Trinity College Dublin have created an innovative new device that will emit single particles of light, or photons, from quantum dots that are the key to practical quantum computers, quantum communications, and other quantum devices. The team has made a significant improvement on previous designs in Read more about An innovative new device for quantum technologies[…]
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second — faster than any other similar device. The compact switch is the first to operate at voltages low enough to be Read more about A major new step toward building a computer that uses light instead of electricity to process information[…]
Soon, powerful quantum computers will be able to easily crack conventional mathematically encrypted codes. Entangled photons generated by a spaceborne quantum source could enable hack-proof key exchange for ultra high security applications. A Fraunhofer research team has developed a highperformance quantum source robust enough for deployment in space. They aim to launch the first European Read more about First European quantum satellite to come in four years[…]
The emerging domain of parallelized quantum information processing opens up new possibilities for precise measurements, communication and imaging. Precise control of multiple stored photons allows efficient handling of this subtle information in large amounts. In the Quantum Memories Laboratory at Faculty of Physics, University of Warsaw a group of laser-cooled atoms has been used as Read more about Quantum memory with record-breaking capacity based on laser-cooled atoms[…]
Physicists from the University of Basel have developed a memory that can store photons. These quantum particles travel at the speed of light and are thus suitable for high-speed data transfer. The researchers were able to store them in an atomic vapor and read them out again later without altering their quantum mechanical properties too Read more about One step closer to the quantum internet[…]
