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.

Harvard researchers are using a chemical process known as triplet fusion upconversion to transform near-infrared photons into high-energy photons. The high-energy photons could be used in a huge range of applications, including a new type of precisely targeted chemotherapy, in which low-energy infrared lasers that penetrate deep into the body could be used to transform innocuous compounds into cancer-fighting drugs.
