Quantum computers have the potential of outperforming classical computers in some optimization and data processing tasks. However, quantum systems are also more sensitive to noise and thus prone to ...

Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have achieved a breakthrough in quantum noise characterization in ...

Decoherence is a fundamental phenomenon through which classical behavior emerges from the quantum laws of nature. It is the main obstacle when scientists harness these laws for information processing.

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Quantum computing is on the verge of catapulting the digital revolution to new heights. Turbocharged processing holds the promise of instantaneously diagnosing health ailments and providing rapid ...
