Tristan Benoist and I have just arXived our paper On bipartite unitary matrices generating subalgebra–preserving quantum operations. We characterize the set of bipartite unitary operators which give quantum operations preserving some subalgebra of the state space, independently of the state of the coupled environment. The main results in the paperContinue reading
RT @_____satvik Hey #MathTwitter! Here's an innocuous looking problem for you. Let S be a d-dimensional subspace of the space of all nxm complex matrices (d <= nm). Determine if there exists a full rank matrix in S.
RT @RaulGarciaPatr1 For all of you that are craving form the lack of arXiv papers today and/or complaining about the quantum hype-r-sphere, you can have a look at the work of @dsfranca and myself that is finally out! nature.com/articles/s4156…
