On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians
Pietro De Checchi, Federico Gallina, Barbara Fresch +1
Stochastic evolution underpins several approaches to the dynamics of open quantum systems, such as random modulation of Hamiltonian parameters, the stochastic Schrodinger equation…

Computability Theory of Closed Timelike Curves
Scott Aaronson, Mohammad Bavarian, Toby Cubitt +4
We study the question of what is computable by Turing machines equipped with time travel into the past; i.e., with Deutschian closed timelike curves (CTCs) having no bound on their…
