Scott Glancy (Fed)

Physicist

I am a physicist researching quantum information theory.  My current research interests include:

  • Statistical analysis of quantum experiments, such as quantum tomography, hypothesis tests of local realism, and secure randomness extraction
  • Quantum optics theory, linear optics, Gaussian quantum states
  • Optical quantum information processing
  • Foundations of quantum mechanics

I have ongoing collaborations with the quantum optics group of Sae Woo Nam, NIST-Boulder's ion storage group, and the ultra-cold atom group of Trey Porto and William Phillips.

 

I work on the Joint Quantum State and Measurement Tomography software project at https://github.com/usnistgov/state_meas_tomo. This software performs simultaneous quantum state and measurement tomography, as described in " Joint Quantum State and Measurement Tomography with Incomplete Measurements" arXiv:1803.08245 [quant-ph].

 

I wrote a fun post for the NIST blog: "Local Realism, Bell's Inequality, and T-Shirts: An Entangled Tale".

 

Here is my CV.
