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 the quantum phenomena that grant quantum computers their unique computational abilities can only be harnessed by isolating them from the warmth of the familiar classical world we inhabit.

A single quantum bit or “qubit”, the equivalent of the binary “zero or one” bit at the heart of classical computing, requires a large refrigeration apparatus to function. However, in many areas where we expect…
