There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make ...

IQM Quantum Computers, the global leader in superconducting quantum computers, has developed a novel quantum error-correcting ...

New research introduces a family of error-correcting codes that reduce qubit overhead by up to 1,000 times compared to today’s leading approach — without requiring any new hardware. ESPOO, Finland & ...

A way to greatly enhance the efficiency of a method for correcting errors in quantum computers has been realized by theoretical physicists at RIKEN. This advance could help to develop larger, more ...

The Innsbruck quantum computer calculates with algorithms that switch back and forth between two different quantum error correction codes to realize error-corrected ...

The work paid off. The codes achieve an encoding rate—a number that indicates the ratio between logical and physical qubits—of up to 30% which Goto says appears to be the world's highest among the ...

Carbon code is different, says Svore. “We do not consider the Carbon code to be an LDPC code,” she says. Technically, Carbon code is a stabilizer code of the Calderbank-Shor-Steane variety, which is a ...

For quantum computers to go from research curiosities to practically useful devices, researchers need to get their errors under control. New research from Microsoft and Quantinuum has now taken a ...
