Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the novel ...

Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current quantum computers encounter a challenge ...

A key factor for the performance of sensors is the speed at which the system returns to its initial state after a disturbance ...

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

A team of physicists has pushed the limits of quantum control by cooling the rotational motion of a nanoscale object to its ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

But RSA worked until the advent of quantum computers. These machines harness the physics of subatomic particles to process information in fundamentally different ways, including factoring long strings ...

A story claims a revolutionary skunk works built a quantum sensor that was used to locate a missing airman by reading his pulse from 40 miles away. But physicists say the laws of biomagnetism make ...

However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

A method that relies on hitting materials with neutrons can measure how much quantum entanglement hides within them, which ...
