Ultrathin metasurface produces web of quantum entangled photons

Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a precisely patterned surface 100 times thinner than paper, … Continue reading Ultrathin metasurface produces web of quantum entangled photons

IBM builds huge super-fridge colder than space to chill quantum computers

Quantum computing requires extremely cold temperatures. To that end, IBM has built and demonstrated a huge “super-fridge” codenamed Project Goldeneye that chills things colder than outer space.Continue ReadingCategory: Computers, TechnologyTags: Quantu… Continue reading IBM builds huge super-fridge colder than space to chill quantum computers

Oxford physicists create network of quantum-entangled atomic clocks

Physicists at the University of Oxford have successfully linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to approach the fundamental limit of precision set by quan… Continue reading Oxford physicists create network of quantum-entangled atomic clocks

Quantum entanglement record set with largest cluster of photons so far

Physicists at the Max Planck Institute have developed an efficient new method to drive the quantum entanglement of photons, and demonstrated it by entangling a record number of photons. The technique could be a boon for quantum computers.Continue Readi… Continue reading Quantum entanglement record set with largest cluster of photons so far

Record-setting quantum entanglement connects two atoms across 20 miles

Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.Con… Continue reading Record-setting quantum entanglement connects two atoms across 20 miles

“Quantum flute” gets light moving in way never seen before

Scientists have created a “quantum flute” that can coax photons to move in sync and interact with each other, which they almost never do in nature. The device could help improve future quantum computer designs.Continue ReadingCategory: Physics, Science… Continue reading “Quantum flute” gets light moving in way never seen before

Atomic-scale quantum circuit marks major quantum computer breakthrough

Engineers in Sydney have demonstrated a quantum integrated circuit made up of just a few atoms. By precisely controlling the quantum states of the atoms, the new processor can simulate the structure and properties of molecules in a way that could unloc… Continue reading Atomic-scale quantum circuit marks major quantum computer breakthrough

Diamond-based quantum computer paired with supercomputers for first time

Quantum computing may have just taken a major step forward, as a supercomputer facility in Australia becomes the first to have a quantum computer integrated into it. The quantum processor, developed by German-Australian start-up Quantum Brilliance, run… Continue reading Diamond-based quantum computer paired with supercomputers for first time

Quantum teleportation achieved between non-adjacent network nodes

Scientists in the Netherlands have made a major step towards quantum computer networks by teleporting quantum information between two nodes that didn’t have a direct link to each other. The breakthrough heralds a faster and more secure communication sy… Continue reading Quantum teleportation achieved between non-adjacent network nodes
