At roughly minus 460 F, absolute zero is abysmally cold, yet at least we can imagine it. Being only a few hundred degrees below zero, it's in the realm of something we can put our minds around.

Pioneers in the quest to reach absolute zero relied on a technique known as the "cascade" process. First, they put a gas in a sealed container under high pressure, then cooled the compressed gas ...

For an idea of how frigid that is, zero Kelvin is -273.15 degrees Celsius or -457.87 degrees Fahrenheit, and is more commonly referred to as absolute zero. There’s a Quantum Way to Get to ...

The new quantum refrigerator – the square object in the centre of the qubit in the image – is based on ... the qubits to temperatures close to absolute zero. Now, researchers at Chalmers ...
