To overcome this problem, high-rate quantum codes, such as quantum low-density parity-check codes, have been considered. With this approach, the logical gates, which make calculations possible, have ...

IQM Quantum Computers, the global leader in superconducting quantum computers, today announced a significant achievement in quantum error correction, using directional tile codes, marking a major step ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

RIKEN scientists tap into AI to find a smarter method for fixing quantum errors, cutting resource demands for stable quantum machines. Theoretical physicists at RIKEN have made a key advance in ...

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

Two quantum information theorists have solved a decades-old problem that will free up quantum computing power. University of Sydney quantum researchers Dominic Williamson and Nouédyn Baspin have ...

Recently, an alternative passive approach has emerged that involves driving continuous periodic motions in the quantum system—so that any noise that accumulates in one cycle of motion can be undone in ...

A new quantum computer designed by Pritzker School of Molecular Engineering researchers uses “reconfigurable atoms,” or qubits that are mobile, making them able ...
