Quantum computers are able to solve complex calculations that would take traditional computers thousands of years in just a few minutes. What if that analytical power is turned inwards towards the ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Entanglement is one of the most valuable resources in the quantum realm – for instance, it is the powerhouse behind quantum encryption – and in theory, it may be possible to extract an infinite amount ...

Nearly a century ago, the physicist Erwin Schrödinger called attention to a quirk of the quantum world that has fascinated and vexed researchers ever since. When quantum particles such as atoms ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...

Similar to humans going on journeys of self-discovery, quantum computers are also capable of deepening their understanding of their own foundations. Researchers from Tohoku University and St. Paul's ...
