Integrating over the unitary group

Code Math Science October 14, 2015March 21, 2018 by jarrodmcc

Quantifying the volumes of different types of quantum states with respect to each other is an interesting tool for analysis that I’ve recently become interested in.  For example, did you know the volume of separable states is super-doubly-exponentially small with respect to all quantum states? That means that if I choose a state of 100 qubits …

Distance is weird in many-particle quantum mechanics

Math Science September 18, 2015September 18, 2015 by jarrodmcc

Distance measures between quantum states are interesting for all kinds of reasons.  I’ve been thinking about them a lot lately as they pertain to machine learning in and around quantum mechanics, as well as just generic approaches to studying many-body quantum systems.  One thing that has stuck with me lately is a peculiarity of distance …
