Build a quantum computer based on the Doppler cooling mechanism

Quantum computers are predicted to solve optimization problems much faster than conventional computers. But how do you build a quantum computer?

Computer chip

A very promising way to make quantum computers is to use ultra-cold atoms as quantum bits. Special lasers can freeze the atoms and hold them still mid-air, using Doppler cooling.

How do you make cold atoms? What kind of laser should you use – and why? Get the answers in this application note.
