As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...

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

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 ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...

While noise can show up anywhere, ECC also can correct deterministic errors, such as those caused by faulty cells. This makes it possible to develop a design and test strategy that leverages some of ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Microsoft and Quantinuum quantum computing researchers just ...

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 ...

Unlike binary bits of information in ordinary computers, “qubits” consist of quantum particles that have some probability of being in each of two states, designated |0 and |1 , at the same time. When ...

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 ...

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness. Unlike binary bits of information in ordinary computers, “qubits” consist ...
