Quantum optimal measurements for clocks and microscopes

Date:  Thursday, October 25th, 2018

Time: 4:00pm

Location: 100 Willamette Hall

Speaker: Mark Kasevich, Stanford

Abstract:

When and how can quantum entanglement be exploited as a resource to improve measurement precision?

This talk will discuss this question in the context of two sensing scenarios:  i) precision atomic clocks [1] and ii) phase contrast optical and electron microscopy [2].  In the first case, massively entangled atomic states have been exploited to realize nearly 20 dB metrological improvement in atomic clock precision.  In the second, quantum optimal performance is

UO Physics and Chemistry Faculty Help Pave the way in Quantum Science Efforts

UO Physics faculty aim to help the United States take a leading role in the fast-evolving quantum technology revolution.

UO physicist Michael Raymer, a Philip H. Knight professor in the Department of Physics, and two colleagues, chemistry professor Andy Marcus and physics professor Brian Smith, have been awarded a $997,000 grant from the National Science Foundation. The award is part of a $31 million NSF program for fundamental quantum research that, together with $281 million in Department of Energy investment, aims to help the United States take a leading role in the fast-evolving quantum

When it comes to magnifying the miniscule, electrons are fundamentally better than visible light. That’s because electrons, which have wavelike properties due to quantum mechanics, have wavelengths a thousand times shorter. Shorter wavelengths produce higher resolution, much like finer thread can create more intricate embroidery. “Electron microscopes are pretty much the only game in town if you want to look at things on the atomic scale,” says physicist Ben McMorran of the University of Oregon.
