The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems ...

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

The team have pushed the boundaries of quantum mechanics beyond what some thought possible. Now they want to go even further ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

That low-frequency fuzz that can bedevil cellphone calls has to do with how electrons move through and interact in materials ...

Physicists have coaxed clusters of thousands of atoms into a delicate quantum limbo, creating a record breaking version of ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
