Error correction occurs in decoding because there are only limited legal states available at any node on the graph. When the bit stream contains an illegal code, the decoder knows an error occurred.

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...

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 ...

I, Brian Wang, interviewed Andrei Petrenko, Head of Product at Quantum Circuits and Neil Wu Becker, Head of Marketing for Quantum Circuits. Quantum Circuits presented at Q2B 2024 Silicon Valley at the ...

Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

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 ...

Whenever we send data — whether it’s audio signals over a phone line, a data stream or a legal document — to someone else, we need to know that what arrives on the other end is identical to what we ...
