The regularized channel Rényi divergence is continuous
Lukas Schmitt, David Sutter
We show that the regularized channel Rényi divergence is continuous at . As consequences, we establish an exponentially strong converse for channel discrimination, a subchann…
Relative entropy representations via tracial joint spectral measures
Lukas Schmitt
We show that for positive semidefinite and the relative entropy can be written as , where denotes Heinävaara's t…
The marginal is pretty good
Lukas Schmitt, Joseph M. Renes, Gui-Long Jiang +1
One-shot information theory measures often require an optimization over states, but the form of these optimizers can be complicated or depend on the initial problem in nonlinear wa…
Essentially optimal gate teleportation
Lukas Schmitt, David Sutter
Gate teleportation allows us to implement a nonlocal unitary using local operations, classical communication (LOCC), and a shared entangled state. Known deterministic teleportation…
Tumula information and doubly minimized Petz Renyi lautum information
Lukas Schmitt, Filippo Girardi, Laura Burri
We study a doubly minimized variant of the lautum information - a reversed analogue of the mutual information - defined as the minimum relative entropy between any product state an…
Circuit cutting with classical side information
Christophe Piveteau, Lukas Schmitt, David Sutter
Circuit cutting is a technique for simulating large quantum circuits by partitioning them into smaller subcircuits, which can be executed on smaller quantum devices. The results fr…
Cutting circuits with multiple two-qubit unitaries
Lukas Schmitt, Christophe Piveteau, David Sutter
Quasiprobabilistic cutting techniques allow us to partition large quantum circuits into smaller subcircuits by replacing non-local gates with probabilistic mixtures of local gates.…
