Synchronizing a few-level quantum system is of fundamental importance to understanding synchronization in deep quantum regime. Whether a two-level system, the smallest quantum system, can be synchronized has been theoretically debated for the past several years. Here, for the ﬁrst time, we demonstrate that a qubit can indeed be synchronized to an external driving signal by using a trapped-ion system. By engineering fully controllable gain and damping processes, an ion qubit is synchronized to…

Observation of Quantum Phase Synchronization in Spin-1 Atoms.

- PhysicsPhysical review letters
- 2020

In experiments with dilute ensemble of laser cooled spin-1 ^{87}Rb atoms, phase difference of spin coherences to synchronize with phases of external classical fields is observed and a blockade of synchronization due to quantum interference and emergence of Arnold-tongue-like features is observed.

Degree of Quantumness in Quantum Synchronization

- PhysicsScientific Reports
- 2019

Following techniques from quantum information, the number of non-commuting observables that synchronize as a measure of quantumness is proposed and illustrated in a quantum system consisting of two weakly interacting cavity-qubit systems.

Mutual information as an order parameter for quantum synchronization

- Physics, Computer Science
- 2015

This work proposes mutual information as a useful order parameter which can capture the emergence of synchronization in very different contexts, ranging from semiclassical to intrinsically quantum-mechanical systems and finds that mutual information can be used as an appropriate figure of merit for determining the synchronization phases independently of the specific details of the system.

Squeezing Enhances Quantum Synchronization.

It is demonstrated that strong entrainment is possible for small values of squeezing, and in this regime, the states are nonclassical.

The results show that state-of-the-art noisy intermediate-scale quantum computers are powerful enough to implement realistic dissipative quantum systems and limitations of current quantum hardware are discussed.

Quantum synchronization in nanoscale heat engines.

The physical phenomenon of synchronization is linked with the emerging field of quantum thermodynamics by establishing quantum synchronization as a mechanism of stable phase coherence by proving that synchronization places an upper bound on the achievable steady-state power of the engine.

This work investigates synchronization in the simplest quantum-mechanical scenario possible, i.e., a quantum- mechanical self-sustained oscillator coupled to an external harmonic drive, and shows that there is a steplike crossover to a synchronized state as a function of the driving strength.
