IBM has managed to dramatically reduce the number of quantum bits, or qubits, required to prevent errors in a quantum computer.

To reduce the chances of errors creeping in, the team built their QEC system to be as simple as possible. It consists of a superconductor inside an aluminium box, with a chamber on either side.

The most famous examples of locally correctable codes are versions of a venerable error-correcting code invented in 1954 by the mathematicians David Muller and Irving Reed (who also helped develop ...

Computerworld QuickStudies The best-known error-detection method is called parity, where a single extra bit is added to each byte of data and assigned a value of 1 or 0, typically according to ...

Physicists achieve fault-tolerant control of an error-corrected qubit To demonstrate the capabilities of its qubits, the QuTech team successfully calculated the dissociation energy of molecular ...
