These electrons were found to be entangled, sharing a deep quantum link, and doing so in ways tied to the fastest possible time in physics. Even more surprising, the effect appeared close to room temperature, hinting that future quantum computers might harness this bizarre state of matter.

Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of generating streams of entangled photons with 92% fidelity. This scalable setup could one day link quantum computers across continents, enable unbreakable communication, and even transform timekeeping by powering a global network of optical atomic clocks that are so precise they’d barely lose a second over the universe’s entire lifetime.

A team at Caltech has now developed a clever solution: converting quantum information into sound waves. By using a tiny device that acts like a miniature tuning fork, the researchers were able to extend quantum memory lifetimes up to 30 times longer than before. This breakthrough could pave the way toward practical, scalable quantum computers that can both compute and remember.
