New quantum technology combines free electrons and photons


Quantum technologies have the ability to alter our lives much like computers and the internet did when they were first created: faster computers, tap-proof communication, better auto sensors. To achieve this, they frequently need special, one-of-a-kind particles, like photons, the building blocks of light. But getting individual particles is difficult and calls for complex procedures. A new technique that simultaneously creates two distinct particles in the shape of a pair is now presented by researchers in a paper that was just published in the journal Science.

Germaine Arend, a PhD candidate at the MPI and the study’s first author, underlines that with an electron-photon pair, all that is necessary to learn about the energy level and temporal appearance of the second particle is to measure the first one.
