To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

In quantum physics, entanglement links particles across space in ways that defy logic. However, there’s a lesser-known phenomenon that’s even more intriguing than entanglement, and it’s called quantum ...

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 ...

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 ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

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 entanglement has long been framed as a strange communication channel between particles, but the latest experiments suggest it can do something more concrete and practical: make light itself ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...
