Research Breakthrough in Entanglement Could Lead to High-Dimensional Encoding of Quantum Information, Future Quantum Devices
Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.
Atomic Institute of TU Wien Develops Quantum Cryptographic Keys Faster, Far More Robust Against Interference
Quantum cryptography Records with Higher-Dimensional Photons Quantum cryptography is one of the most promising quantum technologies of our time: Exactly the same information is generated at two different locations, and the laws of quantum physics guarantee that no third party can intercept this information. This creates a code with which information can be perfectly encrypted. […]
University of Colorado’s New Q-SEnSE Center Producing Cutting Edge Photon Counting Quantum Devices
Researchers at CU Boulder have designed one of the most precise stopwatches yet—not for timing Olympic sprinters and swimmers but for counting single photons, or the tiny packets of energy that make up light.

Benefit to Hybrid Quantum Systems: Physicists Heighten Photon, Magnon Excitation
A team of scientists from NUST MISIS and MIPT have developed and tested a new platform for realization of the ultra-strong photon-to-magnon coupling. The proposed system is on-chip and is based on thin-film hetero-structures with superconducting, ferromagnetic and insulating layers. This discovery solves a problem that has been on the agenda of research teams from different countries for the last 10 years, and opens new opportunities in implementing quantum technologies.
