Quantum Computing Takes a Leap Forward with Extended Qubit Lifespan.

Scientists at Yale University have extended the lifespan of a qubit, the workhorse of quantum computing, by keeping it in its ideal state for twice as long as normal. They achieved this by demonstrating the practicality of quantum error correction (QEC), a process that keeps quantum information intact for longer by introducing redundancy and error removal. The experiment also introduced machine learning AI algorithms to tweak the error correction routine. The research validates a cornerstone assumption of quantum computing and paves the way for practical quantum computers.
