Harvard scientists use optical tweezers to capture ultracold molecules
Using precisely focused lasers that act as “optical tweezers,” Harvard scientists have been able to capture and control individual ultracold molecules – the eventual building-blocks of a quantum computer – and study the collisions between them in more detail than ever before.
