New technique in error-prone quantum computin

Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by UC Berkeley physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.

New technique in error-prone quantum computing makes classical computers sweat

Despite steady improvements in quantum computers, they re still noisy and error-prone, which leads to questionable or wrong answers. Scientists predict that they won t truly outcompete today s "classical" supercomputers for at least five or ten years, until researchers can adequately correct the errors that bedevil entangled quantum bits, or qubits.
