The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature – one can only approach absolute zero. This is the third law of ...

How would you go about determining absolute zero? Intuitively, it seems like you’d need some complicated physics setup with lasers and maybe some liquid helium. But as it turns out, all you need is ...

Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum computing forward. But there's still much work to be done before they can be ...

In this series, physicist Dr Helen Czerski explores the extraordinary science of temperature. She unlocks the extremes of the ...

Physicists at Harvard University demonstrated a new cooling technique for ultracold gases that could help reach temperatures even closer to absolute zero than before—and also lead the way to quantum ...

Molecules containing four atoms are the largest yet to be cooled down to only a hundred billionths of a degree above absolute zero. The techniques researchers use for cooling individual atoms, such as ...
