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 ...

In this new study, the researchers at Google worked to reduce background noise, part of which involved putting their chip in a near absolute zero chamber as the chip was running. They found that ...
