Jason Gallicchio, assistant professor of physics, will discuss “Improving Tests of Quantum Entanglement using Light from Distant Quasars.”
Quantum entanglement, described by Einstein as “spooky action at a distance,” is both fascinating philosophically and is the basis for quantum computing and quantum encryption. The inferred power of entanglement rests on several assumptions, including that the measurement chosen for one particle can be made independent of any influence that can affect the other particle. Rather than take this assumption for granted, I devised and helped carry out an experiment on the Canary Islands that used real-time measurements of the color of incoming photons from two quasars on opposite sides of the universe to choose the measurements on each entangled particle.
This address is part of a series of talks and open house events for those participating in Harvey Mudd's undergraduate Summer Research Program. Refreshments are available in the Galileo Foyer.
