Conditional channel entropy sets fundamental limits on thermodynamic quantum information processing
Himanshu Badhani, Siddhartha Das
The thermodynamic resourcefulness of quantum channels primarily depends on their underlying causal structure and their ability to generate quantum correlations. We quantify this in…
Thermodynamics of quantum processes: An operational framework for free energy and reversible athermality
Himanshu Badhani, Dhanuja G. S., Siddhartha Das
We explore the thermodynamics of quantum processes (quantum channels) by axiomatically introducing the free energy for channels, defined via the quantum relative entropy with an ab…
Erasure cost of a quantum process: A thermodynamic meaning of the dynamical min-entropy
Himanshu Badhani, Dhanuja GS, Swati Choudhary +2
The erasure of information is fundamentally an irreversible logical operation, carrying profound consequences for the energetics of computation and information processing. We inves…
Reduced dynamics in quasi-Hermitian systems
Himanshu Badhani, C. M. Chandrashekar
Evolutions under non-Hermitian Hamiltonians with unbroken symmetry can be considered unitary under appropriate choices of inner products, facilitated by the so-calle…
Thermodynamic work capacity of quantum information processing
Himanshu Badhani, Dhanuja G S, Siddhartha Das
We introduce the resource-theoretic free energy of a quantum channel as the maximal work extractable from the channel as its output equilibrates to a thermal state and its referenc…
Causal and Non-Causal Revivals of Information: A New Regime of Non-Markovianity in Quantum Stochastic Processes
Francesco Buscemi, Rajeev Gangwar, Kaumudibikash Goswami +5
The study of information revivals, witnessing the violation of certain data-processing inequalities, has provided an important paradigm in the study of non-Markovian quantum stocha…
