Research Interests

My research interests are in the foundations of physical probability. I use statistical concepts such as the auto-correlation of a time series to define probability in terms of physically more basic concepts.

This led to a publication on the problem in the axiomatics of Quantum Mechanics which Wigner called Quantum Duality, although it is now more usually called Quantum Measurement.

The simplest rigorous, non-circular proof that d(cos x) = - sin x at the Math Department .

An interesting list of papers on this hot topic of Quantum Information, maintained by the Italian national research centre on Quantum Computers.
