Title: Uncertainty Principles in Krein Space
Authors: Sirous Homayouni and Angelo B. Mingarelli
Abstract summary: Uncertainty relations between two general non-commuting self-adjoint operators are derived in a Krein space. As a consequence there exist classes of non-self-adjoint operators on Hilbert spaces such that the non-vanishing of their commutator implies an uncertainty relation.

Abstract: Uncertainty relations between two general non-commuting self-adjoint operators are derived in a Krein space. All of these relations involve a Krein space induced fundamental symmetry operator, $J$, while some of these generalized relations involve an anti-commutator, a commutator, and various other nonlinear functions of the two operators in question. As a consequence there exist classes of non-self-adjoint operators on Hilbert spaces such that the non-vanishing of their commutator implies an uncertainty relation. All relations include the classical Heisenberg uncertainty principle as formulated in Hilbert Space by Von Neumann and others. In addition, we derive an operator dependent (nonlinear) commutator uncertainty relation in Krein space.

Symmetry-restricted quantum circuits are still well-behaved [45.89137831674385]
We show that quantum circuits restricted by a symmetry inherit the properties of the whole special unitary group $SU(2n)$. It extends prior work on symmetric states to the operators and shows that the operator space follows the same structure as the state space.

Uncertainty relations from state polynomial optimization [3.069335774032178]
We develop a semidefinite programming hierarchy for additive uncertainty relations in the variances of non-commuting dimension observables. The hierarchy is complete, in the sense that it converges to tight uncertainty relations. The techniques apply to a range of scenarios, including Pauli, Heisenberg-Weyl, and fermionic operators.

Annihilating Entanglement Between Cones [77.34726150561087]
We show that Lorentz cones are the only cones with a symmetric base for which a certain stronger version of the resilience property is satisfied. Our proof exploits the symmetries of the Lorentz cones and applies two constructions resembling protocols for entanglement distillation.

We show that the sandwiched R'enyi divergences of finite-dimensional density operators quantify their distinguishability in the strong converse domain. We also initiate the study of the sandwiched R'enyi divergences, and the related problem of the strong converse exponent.
