Quantum Physicists Set New Record For Entangling Photons Together

A new method for entwining the fates of fragments of light has overcome some serious obstacles on the road to photon-based quantum computing.

Ancient Stone Could Hold The Key to Unlocking Quantum Computers

Scientists successfully produced the largest hybrid particles of light and matter ever created. These quasiparticles were made with the help of a piece of stone containing cuprous oxide crystals from an ancient deposit in Namibia.

Two Time Crystals Have Been Successfully Linked Together For The First Time

Physicists have just taken an amazing step towards quantum devices that sound like something out of science fiction.

Quantum computing in silicon hits 99 % accuracy

Researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology.

Physicists supercooled a human-scale object

Scientists have cooled a large, human-scale object to close to its motional ground state. The scientists say they now have a chance to observe the effect of gravity on a massive quantum object.

Scientists overhear two atoms chatting

Each atom carries a small magnetic moment called spin. These spins influence each other. If you give one of them a push, they will start moving together in a very specific way. Atoms can feel each other.

Researchers achieve long-distance quantum teleportation

A joint team of researchers was able to use quantum teleportation to send information over a distance of 44km. If successfully implemented, quantum internet would usher a new era of communication.

A Tiny Glass Bead Goes as Still as Nature Allows

Inside a small metal box on a laboratory table in Vienna, physicists have engineered, perhaps, the quietest place on Earth. At this level of stillness, our conventional wisdom about motion breaks down, as the bizarre rules of quantum mechanics kick in.

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.

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.

'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.
