Code

I often program things. I'm no professional software developer, but it still does the trick.

FT qRAM Circuits, Python tools for fault-tolerant resource estimation of qRAM circuits in the surface code.

Caspar, a Python implementation of our recursive factorization of SU(n) matrices.

pQCS, software for parallel quantum circuit synthesis (downloadable from the qsoft webapge).

Balthasar, a Python package (in progress) for MUBs, Latin Squares, and many other fun things.

PyniteFields, a Python package for working with Galois fields.

The 2-designer, a Python implementation of a protocol for sampling random circuits from a unitary 2-design.

Notes

The following are some topical notes which may or may not be useful for others. Some were written for class projects, others for friends or for fun.

Introduction to quantum computing and quantum annealing (Materials for a lecture series given at TRIUMF, May 2019)

A casual primer on finite fields

Bounded depth quantum circuits (for John Watrous' course on Quantum Complexity Theory, summer 2014)

A brief introduction to unitary 2-designs (for John Watrous' course on Applications of Haar measure in Quantum Information, fall 2014)
