Quantum computers have the potential to run circles around conventional computers by performing incredibly complex calculations and simulations in a fraction of the time. But there’s a problem. Well, there are several, actually, but one of the bigger hurdles is that quantum computers need to be incredibly cold to work. Maybe not for long, though: Two separate research teams each announced breakthroughs that could potentially reduce cooling costs from a few million bucks to a few thousand dollars.

As reported by IEEE Spectrum, both teams presented their discoveries to Nature, where the research papers sit behind a paywall. Intel director of quantum computing Jim Clarke co-authored one of the papers, which describes research led by Menno Veldhorst of Delft University of Technology. The other paper comes from researchers at the University of New South Wales led Andrew Dzurak and Henry Yang. Both teams managed to run quantum operations at over 1 Kelvin. That’s -457.87 Fahrenheit, which is pretty cold, but as we’ll learn, it’s a lot hotter than normal for quantum computing.
