This research demonstrates that multilevel quantum systems (qutrits) can extract more useful work from thermal environments than simpler two-level qubits, effectively mitigating energy loss to decoherence. By modeling heat transfer through generalized amplitude damping channels, the study provides a theoretical pathway toward practical nanoscale devices for energy storage and processing without relying on classical thermodynamic limits.

Quantum Systems Can Still Generate Power Despite Energy Loss

Ergotropy and Work Extraction in Quantum Heat Engines via Quantum Channels Until now, building a quantum heat engine meant accepting inevitable energy losses to environmental ‘noise’. However, new modelling demonstrates that systems utilising multiple quantum levels, qutrits, outperform their simpler two-level counterparts by both extracting more energy and resisting disruptive decoherence. This advance offers a pathway towards practical nanoscale devices for energy storage and processing.

A new quantum heat engine utilising qubits and qutrits interacting with thermal environments via generalised amplitude damping channels has been investigated by Indrajith VS and Disha Verma at National Institute of Technology. Verma and colleagues show how these quantum channels model heat transfer and work extraction, revealing conditions for achieving positive work output. Their thorough analysis of quantum correlations, emission probability, and system-environment interactions demonstrates that multilevel quantum systems outperform two-level systems in both work extraction and resilience to decoherence, offering key insight into the development of practical quantum thermodynamic devices. The coexistence of thermal fluctuations and quantum effects in microscopic systems is currently under investigation. It extends classical thermodynamic principles by…
