Artificial intelligence reduces a quantum physics problem of 100,000 equations to just four equations

Visualization of a mathematical apparatus for capturing the physics and behavior of electrons moving on a lattice. Each pixel represents a single interaction between two electrons. To date, capturing the system accurately has required about 100,000 equations—one per pixel. Using machine learning, scientists reduced the problem to four equations. This means that a compressed version …

Metasurface Entangled Photons

New invention triggers one of quantum mechanics’ strangest and most useful phenomena

In this artist’s rendering of a metasurface, light travels through tiny rectangular structures — the building blocks of the metasurface — and produces entangled pairs of photons of different wavelengths. The device was designed, fabricated and tested through a collaboration between Sandia National Laboratories and the Max Planck Institute for the Science of Light.Image courtesy …

Complex Magnetic Correlations Groundbreaking Quantum Simulator

SU(N) matter is about 3 billion times cooler than deep space – opening a gateway to the quantum realm of high symmetry

An artist’s conception of the complex magnetic correlations observed by physicists in Kyoto University’s groundbreaking quantum simulator using ytterbium atoms about 3 billion times cooler than deep space. The different colors represent the six possible spin states of each atom. Using up to 300,000 atoms, the simulator enables physicists to directly observe how particles interact …

Quantum physicists set new record for entangled photons

Quantum physicists set new record for entangled photons

A new way to entangle the fate of light fragments overcomes some serious obstacles on the way to photon-based quantum computing. Researchers at the Max Planck Institute for Quantum Optics in Germany have succeeded in entangling 14 photons into a state considered optimal for a qubit, more than twice as much as previous attempts, while …
