Quantum algorithm breakthrough

Physicists report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers.

Electron 'teleportation' could push quantum computing forward

Quantum teleportation is an key way to transmit info in quantum computing. In a new step forward, researchers say it may be possible between electrons.

Heat energy leaps through empty space

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.

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.

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. 

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.

China builds world's first space-ground integrated quantum communication network

The first unbreakable intercontinental message was sent through a space-based quantum communication network.

First step towards photonic quantum network

Advanced photonic nanostructures are well on their way to revolutionizing quantum technology for quantum networks based on light. Researchers have now developed the first building blocks needed to construct complex quantum photonic circuits for quantum networks.

Physicists create nano-sized device with huge potential in field of quantum computing

An intricately sculpted device is so tiny it can only be seen under a microscope. But their diamond microdisk could lead to huge advances in computing, telecommunications, and other fields.

Computing with time travel?

Why send a message back in time, but lock it so that no one can ever read the contents? Because it may be the key to solving currently intractable problems.

Quantum Teleportation Beyond The Starship Enterprise

Researchers at the National Institute of Standards and Technology (NIST) have now managed a significant breakthrough.

A living thing in two places at once? This quantum quandary test is limited | Science

A recent proposed microbe experiment based on Schrodinger's counter-intuitive theory would have a scale so small as to be almost meaningless, and other challenges such as consciousness also come into play

Scientists confirm a cornerstone of quantum computing

Quantum physics theory has an odd but fundamental quirk: atoms in a quantum state aren't supposed to move as long as you're measuring them. It sounds preposterous, but Cornell University researchers have just demonstrated that it's real.

More energy efficient transistors through quantum tunneling

Researchers have announced breakthroughs in the development of tunneling field effect transistors, a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level.

Ultracold experiments heat up quantum research

Physicists have experimentally demonstrated for the first time that atoms chilled to temperatures near absolute zero may behave like seemingly unrelated natural systems of vastly different scales, offering potential insights into links between the atomic realm and deep questions of cosmology.
