Modified logarithmic Sobolev inequality for 1D non-commuting Hamiltonians
Ángela Capel, David Pérez-García, Matteo Scandi
Given a finite-range, non-commuting Hamiltonian on a 1D chain of finite spins, we prove a modified logarithmic Sobolev inequality with constant for the heat-bath dyna…
Haah's 3D cubic code thermalizes rapidly
Sebastian Stengele, Libor Caha, Ángela Capel +1
Haah's 3D cubic code was introduced as a candidate for a self-correcting quantum memory in three dimensions, using the absence of string logical operators to obstruct thermal error…
Is rapid mixing stable?
Jordi A. Montañà-López, Barbara Roos, Sebastian Stengele +2
Several physically interesting Lindbladians, such as those describing generic open quantum system models as well as engineered state preparation processes, are often rapidly mixing…
Information Geometry of the Geodesic Quantum -Divergences
Ángela Capel, Pablo Costa Rico
We study the differential, statistical, and geometrical consequences generated by the geodesic quantum -divergences introduced in [14], which are constructed by interpolating th…
Geodesic Quantum -Divergences
Ángela Capel, Pablo Costa Rico
We introduce the geodesic quantum -divergences , , obtained from the affine-invariant geodesic between the standard and maximal relative modular operators.…
Modified logarithmic Sobolev inequalities for CSS codes
Sebastian Stengele, Ángela Capel, Li Gao +5
We consider the class of Davies quantum semigroups modelling thermalization for translation-invariant Calderbank-Shor-Steane (CSS) codes in D dimensions. We prove that conditions o…
