Quantum Physics

Scientists have detected the first evidence of a phenomenon called “quantum superchemistry.” Long predicted but never confirmed, this effect could speed up chemical reactions, give scientists more control over them, and inform quantum computing.

Caltech scientists have created a quantum microscope that taps into the quirky quantum rules to see tiny details much more clearly. Using pairs of entangled photons allows the instrument to double the resolution of images without damaging the sample.

The famous thought experiment of Schrödinger’s Cat neatly sums up a complex quantum phenomenon in terms we can visualize. Now scientists have created the heaviest Schrödinger’s Cat to date, probing the boundaries between quantum and classical physics.

Physicists at Brookhaven National Laboratory have discovered a completely new type of quantum entanglement, the spooky phenomenon that binds particles across any distance. This allowed scientists to peer inside nuclei in more detail than ever before.

Wormholes are a sci-fi staple, and and it's possible that they exist in the real universe. But how would they work? Physicists have now used a quantum processor to simulate a traversable wormhole, teleporting information between two quantum systems.

The 2022 Nobel Prize in Physics has been awarded to three scientists, Alain Aspect, John F. Clauser and Anton Zeilinger, who all conducted some of the first experiments with entangled photons, enabling a future for commercial quantum computers.

Scientists 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, which could replace a roomful of optical equipment.

University of Oxford physicists have 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 quantum mechanics.

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.

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.

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.

It may seem like electronics will always get faster, but at some point the laws of physics intervene. Scientists have now calculated the absolute speed limit – the point at which quantum mechanics prevents microchips from getting any faster.
