The largest number of logical qubits has been linked through quantum entanglement, which is a key step towards quantum computers that can detect and correct errors

The system was also able to detect when one of the neutral atoms that make up a physical qubit disappeared and repeatedly correct for that, according to the announcement.

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the technology to move much beyond the interesting demo phase,
