A group of physicists from Harvard and MIT just built a quantum computer that ran continuously for more than two hours. Although it doesn’t sound like much versus regular computers (like servers that run 24/7 for months, if not years), this is a huge breakthrough in quantum computing. As reported by data-analytics-id=”inline-link” href=”https://www.thecrimson.com/article/2025/10/2/quantum-computing-breakthrough/” target=”_blank” data-url=”https://www.thecrimson.com/article/2025/10/2/quantum-computing-breakthrough/” referrerpolicy=”no-referrer-when-downgrade” data-hl-processed=”none”>The Harvard Crimson, most current quantum computers run for only a few milliseconds, with record-breaking machines only able to operate for a little over 10 seconds.
Although two hours is still a bit…
