Quantum Gates for Fundamental Physics
Quantum gates are at the heart of quantum information processing. Not only are they the building blocks of a quantum computer, but they can also be used to probe fundamental ideas in quantum information. For example, we have used a controlled-sign gate to implement variable strength measurements with which we tested foundational ideas in quantum measurement. I describe the realization of the photonic quantum gate and how we used it for experimental investigations of complementarity, weak measurements, and a Bell inequality in time (the Leggett-Garg inequality).
About the speaker:
Dr. Michael Goggin is a physics professor at Truman State University. His primary research interest is experimental quantum optics involving the construction of sources of bright high-quality entangled photons, implementing linear optical quantum computing protocols and testing the Leggett-Garg inequality.
