Stephen P. Jordan

I study all areas of quantum information, especially algorithms, complexity, and post-quantum cryptography. My interests include simulating chemistry and particle physics on quantum computers, applying methods from physics and topology to computer science, and investigating alternative models of quantum computation, such as the adiabatic, permutational, and one-clean-qubit models.

I have been at NIST since April 2011. From 2014 I have also been a fellow of the joint center for Quantum Information and Computer Science (QuICS) at the University of Maryland. From 2008-2011 I was a postdoc in John Preskill's group at Caltech's Institute for Quantum Information. I spent the Summer of 2008 as a visiting scientist at RIKEN's Digital Materials Laboratory. My Ph.D. advisor was Eddie Farhi in MIT's Center for Theoretical Physics.

The journal version of my paper "Quantum algorithms for quantum field theories" can be accessed free of charge here. See also a podcast and a YouTube video.

I maintain the quantum algorithm zoo, a comprehensive list of quantum algorithms.

Brad Lackey, Michael Jarret and I have developed a heuristic solver for MAXSAT based on a diffusion Monte Carlo simulation of adiabatic optimization. The source code is available on github.

As an undergraduate I wrote some software to perform molecular dynamics simulations using the Tersoff-Brenner potential. You are free to download and modify the sourcecode. [License.]

Publications: See my arxiv page or my CV.

Opportunities: Open positions at QuICS/U. Maryland in quantum information are listed here for graduate students and here for postdocs. US citizens interested in applying to my NRC RAP postdoctoral opportunity are encouraged to contact me via email.
