Quantum vs Classical Erasure: Equal Bounds but Unequal Costs
Jan Neuser, Jake Xuereb, Pharnam Bakhshinezhad +1
The paper compares how much energy is needed to erase a bit of information in classical versus quantum systems when resources are limited, showing that quantum erasure requires mor…
Parameter Estimation in a Continuously Monitored Non-Markovian Quantum System
Erik L. André, Pharnam Bakhshinezhad, Patrick P. Potts +2
Continuous monitoring is a powerful tool for analyzing quantum systems and is increasingly used as a non-demolition technique in quantum metrology. In this context, noisy data acqu…
Thermal Entanglement and Out-of-Equilibrium Thermodynamics in 1D Bose gases
Julia Mathé, Nicky Kai Hong Li, Pharnam Bakhshinezhad +1
We investigate entanglement in and out of equilibrium in a one-dimensional Bose gas in its low-energy Bogoliubov regime. In this Gaussian setting, the state is fully characterized…
Average Equilibration Time for Gaussian Unitary Ensemble Hamiltonians
Emanuel Schwarzhans, Alessandro Candeloro, Felix C. Binder +2
Understanding equilibration times in closed quantum systems is essential for characterising their approach to equilibrium. Chaotic many-body systems are paradigmatic in this contex…
Exploring Noisy Quantum Thermodynamical Processes via the Depolarizing-Channel Approximation
Jian Li, Xiaoyang Wang, Marcus Huber +2
Noise and errors are unavoidable in any realistic quantum process, including processes designed to reduce noise and errors in the first place. In particular, quantum thermodynamica…
Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's…
