Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, ...

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 is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal ...

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) ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

Quantum entanglement arises when multipartite quantum systems exhibit correlations that cannot be explained classically. Such correlations underpin advances in quantum communication, computation and ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

Quantum coherence and entanglement stand as cornerstones of quantum mechanics, underpinning the superposition principle and the nonclassical correlations between spatially or functionally separated ...

Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could strengthen cryptography and other security systems.

In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and antigravity machines.
