Researchers smash through quantum computer storage record

Researchers have broken through a major barrier on the road to building powerful quantum computers. Current quantum computers struggle to store data when they aren’t frozen to incredibly cold temperatures — a state that’s quite impractical for eventual consumer devices — but researchers have now managed to store quantum data at room temperature for a substantial amount of time: thirty-nine minutes, dramatically lapping the previous record of just two seconds.

To create such long-lasting qubits, the researchers began with a piece of silicon and introduced impurities into it, including phosphorus and other elements. Around 10 billion phosphorus ions were placed in the silicon, with each of their nuclei used to store binary data: either a 1, a 0, or both at...
