Entanglement or non-separability constitutes a cornerstone of quantum mechanics from which many of its unique characteristics arise. For example, non-separability in entangled particle pairs leads to apparent instantaneous transfer of information and counterintuitive states of […]
Quanta of light—photons—form the basis of quantum key distribution in modern cryptographic networks. Before the huge potential of quantum technology is fully realized, however, several challenges remain. A solution to one of these has now […]
Whether you need a new villain or an old Spider-Man, your sci-fi movie will sound more scientifically respectable if you use the word “multiverse.” The Marvel multiverse puts different versions of our universe “out there,” […]
Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical […]
While quantum computers represent a revolution in computation, they can’t communicate with each other the way regular computers can—over the internet. If quantum computers could be connected through a quantum network, they could facilitate perfectly […]
A collaboration between Harvard University with scientists at QuEra Computing, MIT, University of Innsbruck and other institutions has demonstrated a breakthrough application of neutral-atom quantum processors to solve problems of practical use. Click to rate […]
To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of […]
Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more energy-efficient […]
A research team was able to generate polarized X-rays with unprecedented purity at the European XFEL in Hamburg. The experiments involved scientists from the Helmholtz Institute Jena, a branch of GSI, Friedrich Schiller University Jena […]
Besides charge, subatomic particles like electrons also carry a property called spin, which is responsible for magnetism. Novel proposals to use spin to store information have emerged in recent years with the promise to be […]
