Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward ...

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 ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

Universal fault-tolerant quantum computing relies on the implementation of quantum error correction. An essential milestone is the achievement of error-corrected ...

This “single-error-correct, double-error-detect” approach is often abbreviated SECDED. The second generation of ECC can correct a whole device, while the third adds internal ECC. In memory, 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 ...

The current generation of quantum hardware has been termed “NISQ”: noisy, intermediate-scale quantum processors. “Intermediate-scale” refers to a qubit count that is typically in the dozens, while ...
