Autonomization of Quantum Systems and the Emergence of the Work Operator
Carlo Cepollaro, Danial Chughtai, Alberto Spalvieri +2
Estimation of work at the quantum scale remains a central challenge in quantum thermodynamics. Canonical approaches have a fundamental drawback: they assume classical control of th…
Quantum Suicide in Many-Worlds Implies P=NP
Veronika Baumann, Alberto Rolandi
In this paper we propose a totally serious algorithm to solve NP problems in polynomial time provided one is willing to wager the fate of all observers in the universe on the many-…
Energy-Time-Accuracy Tradeoffs in Thermodynamic Computing
Alberto Rolandi, Paolo Abiuso, Patryk Lipka-Bartosik +3
In the paradigm of thermodynamic computing, instead of behaving deterministically, hardware undergoes a stochastic process in order to sample from a distribution of interest. While…
Optimal Finite-Time Thermodynamics of Effective Two-Level Systems
Alberto Rolandi
The optimization of the conversion of thermal energy into work and the minimization of dissipation for nano- and mesoscopic systems is a complex challenge because of the important…
An information-theoretic proof of the Planckian bound for thermalization
Paolo Abiuso, Alberto Rolandi, John Calsamiglia +2
We demonstrate that quantum mechanics entails a fundamental lower bound on the thermalization time of any system. At finite temperature, we show that is bounded by half the…
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…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Rapid optimal work extraction from a quantum-dot information engine
Kushagra Aggarwal, Alberto Rolandi, Yikai Yang +8
The conversion of thermal energy into work is usually more efficient in the slow-driving regime, where the power output is vanishingly small. Efficient work extraction for fast dri…
Finite-Time Processes In Quantum Thermodynamics: The Limits Of Irreversibility
Alberto Rolandi
The emergence of irreversibility in physical processes, despite the fundamentally reversible nature of quantum mechanics, remains an open question in physics. This thesis explores…
Collective advantages in finite-time thermodynamics
Alberto Rolandi, Paolo Abiuso, Martí Perarnau-Llobet
A central task in finite-time thermodynamics is to minimize the excess or dissipated work when manipulating the state of a system immersed in a thermal bath. We cons…
Optimal control of dissipation and work fluctuations for rapidly driven systems
Alberto Rolandi, Martí Perarnau-Llobet, Harry J. D. Miller
To achieve efficient and reliable control of microscopic systems one should look for driving protocols that mitigate both the average dissipation and stochastic fluctuations in wor…
Finite-time Landauer principle beyond weak coupling
Alberto Rolandi, Martí Perarnau-Llobet
Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing information. Its saturation requires a reversible isothermal process, and hence infinite time. W…
Pareto-optimal cycles for power, efficiency and fluctuations of quantum heat engines using reinforcement learning
Paolo Andrea Erdman, Alberto Rolandi, Paolo Abiuso +2
The full optimization of a quantum heat engine requires operating at high power, high efficiency, and high stability (i.e. low power fluctuations). However, these three objectives…
Extensive Rényi entropies in matrix product states
Alberto Rolandi, Henrik Wilming
We prove that all Rényi entanglement entropies of spin-chains described by generic (gapped), translational invariant matrix product states (MPS) are extensive for disconnected sub-…
