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 @MJBiercuk Nice work employing actual data from activity in #quantumcomputing to project forward on capability. Conclusion: #factoring via #shor (for RSA) unlikely to be demonstrated at scale until after 2039. arxiv.org/abs/2009.05045 pic.twitter.com/kf1XxKhLgW
RT @thienan496 Roland Speicher has just uploaded a fantastic course on random matrices arxiv.org/abs/2009.05157 Derivation of the Tracy-Widom law, applications to longuest increasing subsequence, and many other exciting topics 😍 pic.twitter.com/w2DNZdimeI
RT @dsfranca New paper out with the great @RaulGarciaPatr1: Limitations of optimization algorithms on noisy quantum devices (scirate.com/arxiv/2009.055…) How many errors you can afford before your noisy quantum computer performs as well as my laptop when it comes to optimization?
