Description

In this talk, we will consider quantum-information-theoretic settings in which nonunitary operators arise naturally, including 2-dimensional extensions of the ZX-calculus. We apply this perspective to scenarios in distributed quantum computing and quantum networking where the actualization of asynchronous, low-latency quantum communication protocols necessitates nonunitary gates for correct behaviour. The talk draws upon several separate joint projects with, respectively, M. Azam (arXiv:2210.03556); J. Bell and F. Butler (in preparation); and J. Peckham and D. Makharoff (arXiv:2407.14987). Nonetheless, there is a continuous narrative across these works.
