It is only one degree warmer than absolute zero or zero on the Kelvin scale – it is the lowest temperature that’s theoretically possible.

For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C). That's because ...

But unlike these other types, spin qubits can be made on a massive scale using existing equipment. However, spin qubits need to be kept at temperatures below 1 kelvin (just above absolute zero) to ...

The Kelvin scale, used mainly in science and engineering, starts at absolute zero, where atomic movement stops. To convert from Celsius to Kelvin, you simply add 273.15 to the Celsius temperature.

In a recent study published in Nature Communications, a group of scientists from Germany demonstrated that single atoms can be steered in a chosen direction at near absolute zero temperatures (4 ...

However, spin qubits must be kept at temperatures below 1 kelvin to preserve their information. To scale-up they also need to be controlled and measured using complex, integrated electronics.

In 1848, he published a paper, ‘On an Absolute Thermometric Scale’, which stated that this ‘absolute zero’ was, in fact, -273 degrees Celsius.

To reach absolute zero, all of the particles within an object have to stop moving.

The temperature scale that is based upon absolute zero, Kelvin, is widely used by scientists today and is named after him.
