Microsoft, Quantinuum Claim Breakthrough in Quantum Computing

The move is the latest in a race to perfect quantum computing

Microsoft and Quantinuum on Wednesday said they have achieved a key step in making quantum computers a commercial reality by making them more reliable.

The move is the latest in a race to perfect quantum computing in which tech firms, such as Microsoft, Alphabet's Google and IBM, are jostling with both rivals and nation states to create machines that take advantage of quantum mechanics to promise speeds far faster than conventional silicon-based computers. Those quantum machines could make feasible scientific calculations that would otherwise take millions of years with today's classical computers.

But the fundamental unit of quantum computers - called a "qubit" - is fast but finicky, producing data errors if the quantum computer is even slightly disturbed. To solve that problem, quantum researchers often build more physical qubits than needed and use error-correction techniques to yield a smaller number of reliable and useful qubits.
