The researchers believe this new device can be scaled up to solve specific problems that are too complex for digital computers to solve, such as simulating room-temperature superconductors. Physicists ...

This is the International Year of the Quantum, celebrating quantum science and its many applications. It also marks the centenary of Werner Heisenberg’s seminal work in modern physics. In recent years ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

What makes something quantum? This question has kept a small but dedicated fraction of the world’s population – most of them quantum physicists – up at night for decades. At very small scales, we know ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level ...

“There’s a whole quest to build a quantum computer,” Frank Verstraete, one of Belgium’s top quantum physicist, tells me. “All the big technology companies like Google and Amazon and IBM are pouring in ...

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, ...

Dr Fabian Laudenbach of the Austrian Institute of Technology tells us why the theory of Schrödinger’s cat might not be the best way to explain quantum physics. Dr Fabian Laudenbach received his PhD in ...

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 ...
