Quantum

Researchers have demonstrated a quantum microscope that can break through a fundamental barrier faced by regular microscopes and see tiny structures that are normally invisible. The device “squeezes” light to snap images with far greater clarity.

A quantum internet could one day allow quantum computers to team up and tackle some gigantic problems. Researchers at Toshiba are a step closer, demonstrating quantum communications sent over a record-breaking 600 km (373 miles) of optic fiber.

Quantum technology is bursting with potential, but controlling atoms and molecules keeps proving tricky. In a breakthrough new study, physicists have successfully wrangled thousands of molecules into a single unified quantum state for the first time.

Dark matter makes up the majority of matter in the universe, but it’s strangely shy about making its presence known. Now physicists have designed a new test to search for signs of two candidate particles, using the quirky world of quantum technology.

There’s no such thing as random in classical physics – for true randomization you need to turn to quantum physics. Now scientists have done just that, creating secure encryption keys based on the genuine randomness of quantum vibrations of diamond.

Researchers in China have demonstrated a quantum communication network where entangled photons are beamed between drones and ground stations, successfully maintaining their quantum link over a distance of 1 km.

Princeton physicists have accidentally discovered an unexpected quantum behavior in an insulator that was thought to be unique to metals. The find suggests a brand new type of quantum particle, which the team calls a neutral fermion.

A quantum internet would be much faster and more secure than the regular web – and now it may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Atomic clocks are our most precise timekeepers, with the best ones keeping time to within one second in 15 billion years. But there’s always room for improvement, as researchers at MIT have now demonstrated with a new quantum-entangled atomic clock.

A Chinese quantum computer called Jiuzhang has apparently achieved "quantum supremacy" – conducting a calculation in 200 seconds that would take a regular supercomputer a staggering 2.5 billion years to complete.

Engineers at Brookhaven National Laboratory have designed a strange new X-ray microscope that takes advantage of the spooky world of quantum physics to “ghost image” biomolecules in high resolution but at a lower radiation dose.

Progress on quantum computers may soon stall. Cosmic rays streaming to Earth can interfere with the integrity of information in quantum computers, and now an MIT team has shown just how vulnerable they are and what it might take to protect them.
