In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

A study published in April 2026 in Proceedings of the Royal Society A shows a different possibility. Researchers demonstrated ...

During the inflationary epoch the Universe underwent an exponential expansion driven by a scalar inflaton field. Quantum fluctuations of this field and of the metric were stretched beyond the Hubble ...

ETH Zurich scientists have levitated a tower of three nano glass spheres using optical tweezers, suppressing almost all classical motion to observe quantum zero-point fluctuations with unprecedented ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...

A ‘quantum processor’ has solved a physics problem on the behaviour of magnetism in certain solids that would take hundreds of thousands of years to calculate on the largest conventional ...

Quantum computers are still in their infancy. Presently limited to 100 or so error-prone qubits, the quantum equivalents to classical bits, they are far from supreme calculating machines that are ...
