Dark Excitonic State Preparation in a Symmetry‐Protected Open Quantum Battery

Advanced Quantum Technologies, EarlyView.
An optical charging protocol is presented for an excitonic quantum battery that prepares the system in a symmetry‐protected dark excited state. Using a continuous‐wave laser followed by controlled relaxation, the system stores energy in a state resilient to environmental losses. Abstract Previous work (J. Phys. Chem.

Probing Quantum Anomalous Heat Flow Using Mid‐Circuit Measurements

Advanced Quantum Technologies, EarlyView.
Using IBM's prototype quantum computers with mid‐circuit measurement capabilities, researchers caught heat flowing from a colder to a hotter qubit — impossible in everyday physics. This eye‐catching reversal, driven by quantum correlations between the qubits, doubles as a stress‐test for today's noisy hardware and a blueprint for future quantum ...

Magnetic Dipolar Quantum Battery with Spin‐Orbit Coupling

Advanced Quantum Technologies, EarlyView.
The study explores a magnetic dipolar system influenced by Zeeman splitting, DM, and KSEA interactions, focusing on quantum resources in both closed and open systems. By analyzing the Gibbs state and solving the Lindblad equation, it examines the effects of thermal and dephasing noise on coherence, discord, and entanglement.

Dynamical Phase Transitions in Open Quantum Walks

Advanced Quantum Technologies, EarlyView.
This work investigates dynamical phase transitions in discrete‐time quantum systems, highlighting the emergence of first‐ and second‐order transitions depending on whether detailed balance is preserved or broken. Using minimal quantum networks and quantum walks with internal degrees of freedom, the study reveals how spectral properties of the ...
