Honeywell, Google bring practical quantum computers a big step closer

Honeywell’s quantum computer uses ytterbium atoms trapped in this chamber, about the size of a football, to perform computations. Honeywell Honeywell and Google have detailed dueling demonstrations of logical qubits, a technology that can correct errors in potentially powerful but notoriously finicky quantum computers. In a research paper released Wednesday, Honeywell […]

Quantum Computing on a Chip: Brace for the Revolution

In a moment of triumph that’s being hailed as equivalent to the move from room-scale silicon technology down to desk-sized machines, quantum computing has now gone chip-scale — down from the room-scale contraptions you might have seen elsewhere, including in science fiction.  The development has been spearheaded by Cambridge-based quantum […]
