Quantum Computing

Scientists have created a “quantum flute” that can coax photons to move in sync and interact with each other, which they almost never do in nature. The device could help improve future quantum computer designs.

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound waves.

Engineers have demonstrated a quantum integrated circuit made of just a few atoms. By precisely controlling the quantum states of the atoms, the processor can simulate the structure and properties of molecules, which could unlock new materials.

A quantum processor, developed by German-Australian start-up Quantum Brilliance, runs at room temperature, and will now work in tandem with classical supercomputers at the Pawsey Supercomputing Research Centre.

Scientists in the Netherlands have made a major step towards quantum computer networks by teleporting quantum information between two nodes without a direct link to each other. The breakthrough heralds a faster and more secure communication system.

Researchers in Japan have developed a new method for making 2-in wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data – the equivalent of a billion Blu-Ray discs.

Researchers have demonstrated key tech that could help scale up quantum computers, creating a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so atoms can be manipulated without disturbing their neighbors.

Three teams of scientists have achieved a major milestone in quantum computing. All three groups demonstrated better than 99 percent accuracy in silicon-based quantum devices, paving the way for practical, scalable, error-free quantum computers.

An exotic state of matter originally hypothesized almost 50 years ago has been observed for the first time. Created by Harvard researchers, this material called quantum spin liquid could eventually help improve quantum computers.

Time crystals sound like something a video game character would be trying to collect, but this bizarre phase of matter is very real – and now one of them has been created in Google’s quantum processor, Sycamore.

Quantum computers are so far held back by their complexity. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single atom is entangled with a series of photons to process and store information.

IBM has unveiled the Eagle, the world’s most powerful quantum processor. Boasting 127 quantum bits (qubits), the Eagle is a major step towards commercial quantum computers outperforming traditional machines.
