The real world can be complex and unpredictable, where the behaviors of even the most steady and proven mechanisms can be fraught with unanticipated outcomes. In technological fields, scientists and ...
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 ...

Quantum error correction codes enable efficient scaling to hundreds of thousands of qubits
In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, ...
Written for you by our author Sam Jarman, edited by Sadie Harley, and fact-checked and reviewed by Robert Egan —this article is the result of careful human work. We rely on readers like you to keep ...
There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...
The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.) and the Nagoya Institute of Technology (NITech, President: OBATA Makoto), collaborated with ...
For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...
"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 ...
