Google researchers demonstrated they could reduce errors in calculations while increasing the number of physical quantum bits (qubits) in a 'logical qubit,' a building block of large-scale quantum computers.
A UK University team developed a system able to transport information from one chip to another with a reliability of 99.999993% at record speeds.
The Nobel Prize for Physics 2022 has been awarded to three physicists working on quantum mechanics - Alain Aspect from France, John Clauser from the United States and Anton Zeilinger from Austria.
Another record has been broken on the way to fully operational and capable quantum computers: the complete control of a 6-qubit quantum processor in silicon. Researchers are calling it "a major stepping stone" for the technology.
A new method for entwining the fates of fragments of light has overcome some serious obstacles on the road to photon-based quantum computing.
Australian scientists have created the world's first-ever quantum computer circuit – one that contains all the essential components found on a classical computer chip but at the quantum scale.
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.
The Frontier supercomputer has now become the world's first known supercomputer to demonstrate a processor speed of 1.1 exaFLOPS (1.1 quintillion floating point operations per second, or FLOPS).
There was a time, not so long ago, when computers occupied entire rooms. Today, some processing units can come as small as a few specks of dust.
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.
Random errors incurred during computation are one of the biggest obstacles in quantum computing. Researchers have now demonstrated a technique that allows errors to be detected and corrected in real time.
The new chip has 127 "qubits", twice as many as the previous IBM processor. The company called its new Eagle processor "a key milestone on the path towards practical quantum computation".
Australian scientists and Microsoft Corporation invented a single chip that can generate control signals for thousands of qubits, when the world’s biggest quantum computers currently operate with just 50 or so qubits.
Physicists report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers.
Fugaku was jointly developed by Riken and the firm Fujitsu and has a speed of roughly 415.53 petaflops—2.8 times faster than the second-ranked US Summit supercomputer's 148.6 petaflops.
