Mathematical Physics

Articles in this category focus on areas of research that illustrate the application of mathematics to problems in physics, develop mathematical methods for such applications, or provide mathematically rigorous formulations of existing physical theories. Submissions to math-ph should be of interest to both physically oriented mathematicians and mathematically oriented physicists; submissions which are primarily of interest to theoretical physicists or to mathematicians should probably be directed to the respective physics/math categories

A single Pfaffian gives Gaussian-state amplitudes in any Pauli basis

Odd and even qubit counts become polynomial-time, so tomography and entanglement checks scale past a thousand sites.
