When sand grains wedge together in a funnel, the whole column locks up. Something strikingly similar can happen to quantum ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

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

Controlling quantum states with high precision—and entangling particles—has long been the goal of researchers pushing the boundaries of quantum technology. Although great strides have been made across ...

Quantum physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough ...

A research team led by Prof. Lin Yiheng from the University of Science and Technology of China (USTC), collaborating with Prof. Yuan Haidong from the Chinese University of Hong Kong, succeeded in ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

For decades, confirming quantum entanglement meant isolating a handful of particles, cooling them to near absolute zero, and ...

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 ...
