Power-law entanglement growth from typical product states
Physical Review Research, 2019 Generic quantum many-body systems typically show a linear growth of the entanglement entropy after a quench from a product state. While entanglement is a property of the wave function, it is generated by the unitary time-evolution operator and is ...

Notes on time entanglement and pseudo-entropy
European Physical Journal C: Particles and FieldsFollowing arXiv:2210.12963 [hep-th], we investigate aspects of the time evolution operator regarded as a density operator and associated entanglement-like structures in various quantum systems.

Scalable modular architecture for universal quantum computation
SciPost PhysicsUniversal quantum computing requires the ability to perform every unitary operation, i.e., evolution operator controllability. In view of developing resource-efficient quantum processing units (QPUs), it is important to determine how many local controls ...

An integral operator on the classes \(\mathcal{S}^{\ast}(\alpha )\) and \(\mathcal{CVH}(\beta )\)
, 2015 The purpose of this paper is to study some properties related to convexity order and coefficients estimation for a general integral operator. We find the convexity order for this operator, using the analytic functions from the class of starlike functions

Evolution: The Universal Operator [PDF]
This paper argues that evolution is not a biological mechanism but a universal operator: a substrate‑independent process that transforms undifferentiated possibility into coherent, self‑maintaining form.

Electronic Journal of Differential Equations, 2009 We give conditions for the parabolic evolution operator to be analytic with respect to a coefficient operator. We also show that the solution of a homogeneous parabolic evolution equation is analytic with respect to the coefficient operator and to ...

Nonexponential evolution equations and operator ordering
, 2005 Nonexponential evolution equations can be treated using a formalism involving the evolution operator method, which, unlike the ordinary case, is not expressed in terms of exponential operators.
