Operator Algebras and Third Quantization
Yidong Chen, Marius Junge, Nima Lashkari
In quantum gravity, the gravitational path integral involves a sum over topologies, representing the joining and splitting of multiple universes. To account for topology change, on…
Generalized Poincaré inequality for quantum Markov semigroups
Marius Junge, Jia Wang
We prove a noncommutative -Poincaré inequality for trace-symmetric quantum Markov semigroups on tracial von Neumann algebras, assuming only the existence of a spectral gap.…
How Far do Lindbladians Go?
Jihong Cai, Advith Govindarajan, Marius Junge
We study controllability of finite-dimensional open quantum systems under a general Markovian control model combining full coherent (unitary) control with tunable dissipative chann…
Strong converse rate for asymptotic hypothesis testing in type III
Marius Junge, Nicholas Laracuente
We extend from the hyperfinite setting to general von Neumann algebras Mosonyi and Ogawa's (2015) and Mosonyi and Hiai's (2023) results showing the operational interpretation of sa…
