Defines a resource theory of GPT-contextuality whose free operations are classical systems and univalent simulations, yielding monotones including classical excess (minimal embedding error into infinite classical systems) and parity-oblivious multiplexing success probability, with noncontextual GPTs
Hybrid qubit-qutrit quantum battery shows oscillatory ergotropy and power with constant capacity, enhanced by nonclassical correlations, and mapped to a room-temperature nickel-radical molecular complex.
A quantum autonomous thermal machine generates entanglement in an external two-qubit system only under thermodynamic cycle A, which exhibits stronger non-Markovianity and higher coherence.
