Complex quantum networks: a topical review

J Nokkala, J Piilo, G Bianconi - Journal of Physics A …, 2024 - iopscience.iop.org
These are exciting times for quantum physics as new quantum technologies are expected to
soon transform computing at an unprecedented level. Simultaneously network science is …

Local versus global master equation with common and separate baths: superiority of the global approach in partial secular approximation

M Cattaneo, GL Giorgi, S Maniscalco… - New Journal of …, 2019 - iopscience.iop.org
Open systems of coupled qubits are ubiquitous in quantum physics. Finding a suitable
master equation to describe their dynamics is therefore a crucial task that must be …

Algebraic theory of quantum synchronization and limit cycles under dissipation

B Buča, C Booker, D Jaksch - SciPost Physics, 2022 - scipost.org
Synchronization is a phenomenon where interacting particles lock their motion and display
non-trivial dynamics. Despite intense efforts studying synchronization in systems without …

Synchronizing the smallest possible system

A Roulet, C Bruder - Physical review letters, 2018 - APS
We investigate the minimal Hilbert-space dimension for a system to be synchronized. We
first show that qubits cannot be synchronized due to the lack of a limit cycle. Moving to larger …

Quantum synchronisation enabled by dynamical symmetries and dissipation

J Tindall, CS Muñoz, B Buča, D Jaksch - New Journal of Physics, 2020 - iopscience.iop.org
In nature, instances of synchronisation abound across a diverse range of environments. In
the quantum regime, however, synchronisation is typically observed by identifying an …

Nonequilibrium transition between dissipative time crystals

A Cabot, GL Giorgi, R Zambrini - PRX Quantum, 2024 - APS
We show a dissipative phase transition in a driven nonlinear quantum oscillator in which a
discrete time-translation symmetry is spontaneously broken in two different ways. The …

Seeding crystallization in time

M Hajdušek, P Solanki, R Fazio, S Vinjanampathy - Physical Review Letters, 2022 - APS
We introduce the concept of seeding of crystallization in time by studying the dynamics of an
ensemble of coupled continuous time crystals. We demonstrate that a single subsystem in a …

Cooperation and competition in synchronous open quantum systems

T Murtadho, S Vinjanampathy, J Thingna - Physical Review Letters, 2023 - APS
Synchronization between limit cycle oscillators can arise through entrainment to an external
drive or through mutual coupling. The interplay between the two mechanisms has been …

Quantum nonstationary phenomena of spin systems in collision models

Y Li, X Li, J ** - Physical Review A, 2023 - APS
We investigate the nonstationary phenomenon in a tripartite spin-1/2 system in the collision
model (CM) framework. After introducing the dissipation through the system-environment …

Observation of quantum phase synchronization in a nuclear-spin system

VR Krithika, P Solanki, S Vinjanampathy, TS Mahesh - Physical Review A, 2022 - APS
We report an experimental study of phase synchronization in a pair of interacting nuclear
spins subjected to an external drive in nuclear magnetic resonance architecture. A weak …
