Scientists in Japan have developed a new way to instantly detect elusive quantum “W states,” a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, ...

Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as ‘momentary’ or ‘instantaneous’: An electron orbits the nucleus of an atom – in ...

An atom is hit by a laser pulse. One electron is ripped out of the atom, another electron is shifted into a state with higher energy. Quantum theory describes events that take place on extremely short ...

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 ...

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of ...

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 ...

The idea of a quantum internet has long been a subject of fascination and speculation. Its promise of secure, instantaneous communication over vast distances, without the threat of interception or ...

The modern scientific world prides itself on precision, empirical rigour, and the pursuit of measurable truth. Yet, some of its most revolutionary discoveries—particularly in quantum physics—have ...
