Scott Glancy


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 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.


Department of Commerce Gold Medal 2016 awarded to the team that performed one of the first loophole-free tests of local realism.

Paul Ehrenfest Best Paper Award for Quantum Foundations 2015 for "A Strong Loophole-Free Test Of Local Realism".

Information Technology Laboratory Outstanding Contribution Award 2015 for development and application of quantum tomography tools.

Information Technology Laboratory Outstanding Journal Paper Award 2014 for "Efficient Quantification Of Experimental Evidence Against Local Realism".

Boston College Outstanding Teaching Assistant Award 1999.

Large-scale quantum computers will inevitably require quantum gate operations between widely separated qubits, even within a single quantum information

Chained Bell inequality experiment with high-efficiency measurements

We report correlation measurements on two 9Be+ ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled
