Quantum synchronization: A tutorial guide [0.0]
This tutorial review offers a systematic framework for analyzing synchronization in classical and quantum dynamical systems.<n>Starting from amplitude-phase dynamics, we introduce topics of relevance, such as phase locking, the Adler equation, Arnold tongues, and the Kuramoto model.<n>We then formulate the corresponding description for quantum limit-cycle oscillators using Lindblad master equations and phase-space methods.

Synchronization in the quantum regime [0.0]
Can synchronization, the widespread spontaneous emergence of coordinated dynamics in classical nonlinear systems, also occur in the quantum regime?<n> Typical quantum features such as the linearity of time evolution and the presence of quantum noise seem to hinder the appearance of synchrony at the microscopic level.<n>We here survey recent theoretical and experimental advances in quantum synchronization, ranging from the characterization of synchronous oscillations to genuinely nonclassical forms of synchrony to many-body synchronization on quantum networks.

Quantum Synchronization and Dissipative Quantum Sensing [0.0]
We develop a framework to characterize several aspects of quantum synchronization. We show that the quantum Fisher information (QFI) serves as a system-a measure of quantum synchronization. We show how the QFI matrix can be used to determine the optimal drive that maximizes quantum synchronization.

Quantum algorithms for quantum dynamics: A performance study on the spin-boson model [68.8204255655161]
Quantum algorithms for quantum dynamics simulations are traditionally based on implementing a Trotter-approximation of the time-evolution operator. variational quantum algorithms have become an indispensable alternative, enabling small-scale simulations on present-day hardware. We show that, despite providing a clear reduction of quantum gate cost, the variational method in its current implementation is unlikely to lead to a quantum advantage.
