A new study led by Prof Dimi Culcer (UNSW/FLEET), indicates electron holes may be the solution to operational speed/coherence trade-off, and the potential scaling up of qubits to a mini-quantum computer. One way to make a quantum bit is…

The U.S. Army funded research may provide the groundwork for future quantum communication networks and large-scale quantum computers. Researchers sent entangled qubit states through a communication cable linking one quantum network node to…

Once quantum computers are ubiquitous, a quantum internet will need to be in place to communicate. Purdue University is addressing the challenge of developing quantum networks able to support more than a few users. Their research, published…

A central challenge of powerful quantum computing is the ability to build universal quantum computers from fragile quantum components. Quantum error correction (QEC) is used in quantum computing to protect quantum information from errors…

Paul Scherrer Institute (PSI) researchers have proposed a detailed plan of how faster and better-defined quantum bits—qubits—can be created. The researchers demonstrated how the qubits can be activated, entangled, used as memory bits,…

In quantum computing, entanglement is the method used to fuse individual quantum systems into one, which exponentially increases their total computational capacity. Scientists from Finland, Russia, China, and the USA demonstrated that…

One of the biggest challenges of quantum physics is that work to develop quantum computers has to be done at very very low temperatures.  Now, an international team led by researchers at Princeton University has uncovered a new class of…

The ability to travel through space without also having to travel through time has been the stuff of legend for centuries. While the genie from Aladdin’s first lamp may be an early example, teleportation is most commonly the stuff of comedy…

The recent claim by Google AI that its Sycamore quantum processor can complete a task in 200 seconds that would take a state-of-the-art supercomputer approximately 10,000 years to complete illustrates more than the power of quantum…
