Heat energy leaps through empty space

A new study shows that heat energy can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon called the Casimir interaction. It could have profound implications for the design of computer chips.

A surprising new study shows that heat energy can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon. It could have profound implications for the design of computer chips and other nanoscale electronic components.

'Invisibility cloak' that looks closer to reality

Harry Potter’s ‘invisibility cloak’ appears closer to reality as Canadian camouflage manufacturer Hyperstealth Biotechnology has applied for patents on its ‘Quantum Stealth’ material.

Achieving quantum supremacy

Researchers have made good on their claim to quantum supremacy. Using 53 entangled quantum bits ('qubits'), their Sycamore computer has taken on -- and solved -- a problem considered intractable for classical computers.

Blueprint for 'quantum battery' that doesn't lose charge

This quantum battery is a tiny, nano-size battery meant to be used for applications on the nano scale but the research provides a theoretical demonstration that creating a loss-free quantum battery is possible.

New record with entangled quantum bits

An international team have succeeded in transforming 20 entangled quantum bits into a state of superposition. This is an important step in the development of quantum computers after the old record of 14 qubits remained unchanged since 2011. 

Reversing the flow of time on a quantum computer

Researchers have developed an algorithm to simulate returning a particle briefly to the past. The results suggest new paths for exploring the backward flow of time in quantum systems.

Quantum structures in super-chilled helium may mirror early universe

For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object may explain how the universe cooled down.

Superradiance: Quantum effect detected in tiny diamonds

An atom gives off energy and causes many other atoms in its vicinity to emit light as well. This phenomenon is called 'superradiance'. For the first time, this phenomenon has now bean measured in a solid-state system.

World-first quantum computer simulation of chemical bonds

Physicists have now demonstrated the world-first simulation of a chemical bond using trapped ion qubits, one of the most promising pathways to full-scale quantum computing.

NASA to create coldest place in the universe

The agency just launched the Cold Atom Lab, a box that takes advantage of microgravity aboard the International Space Station and creates a temperature roughly 10 billion times colder than the vacuum of space.

Physicists find signs of a time crystal

Physicists have uncovered hints of a time crystal. Time crystals, first identified in 2016, are different from ordinary crystals, - their atoms spin periodically, first in one direction and then in another.

Quantum entanglement in massive atom clouds

Now three independent European research groups have managed to entangle not just a pair of particles, but separated clouds of thousands of atoms.

Quantum entanglement has now been made a reality in objects

The researchers managed to bring the motions of two individual vibrating drumheads -- fabricated from metallic aluminium on a silicon chip -- into an entangled quantum state.

A new state of matter

Physicists have identified a new state of matter whose structural order operates by rules more aligned with quantum mechanics than standard thermodynamic theory.
