Peaking at Quantum Systems

Jonathan Monroe, Washington University in St. Louis

Quantum measurements are noisy. Despite experimentalists' best efforts, noise persists for any and all precision measurements. Uncertainty relations set the lower bound for this noise. In this talk, I will describe efforts to circumvent quantum noise through the use of partial quantum measurements. An entropy-based uncertainty relation predicts new bounds for partial measurements, and the experiment approaches this limit. The method achieves a slight improvement over the traditional Heisenberg bound, and decoherence plays a surprising role.

I'll also discuss a bit of my experience during an internship at Boeing. I'll talk about the science I did, and what it was like doing physics in an industry environment.
