Thermodynamic Networks: Harnessing Non-Equilibrium Steady States for Computation
Patryk Lipka-Bartosik, Gianmichele Blasi, Javier Lalueza Puértolas +3
We introduce thermodynamic networks, a general framework for autonomous, physics-based computation using non-equilibrium steady states. These networks are modeled as a collection o…
The minimal example of quantum network Bell nonlocality
Erwan Don, Jessica Bavaresco, Patryk Lipka-Bartosik +3
In recent years, the study of Bell nonlocality has been generalized to quantum networks, where multiple independent sources distribute physical systems to distant parties who perfo…
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…
The power of quantum catalytic local operations
Patryk Lipka-Bartosik, Jessica Bavaresco, Nicolas Brunner +1
A key result in entanglement theory is that the addition of a catalyst dramatically enlarges the set of possible state transformations via local operations and classical communicat…
All incompatible sets of measurements can generate Buscemi nonlocality
Andrés F. Ducuara, Patryk Lipka-Bartosik, Cristian E. Susa +1
The presence of Bell-nonlocality in the correlations arising from measuring spatially-separated systems guarantees that the sets of measurements used are necessarily incompatible.…
Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequali…
Thermodynamic Algorithms for Quadratic Programming
Patryk-Lipka Bartosik, Kaelan Donatella, Maxwell Aifer +4
Thermodynamic computing has emerged as a promising paradigm for accelerating computation by harnessing the thermalization properties of physical systems. This work introduces a nov…
Minimizing Dissipation via Interacting Environments: Quadratic Convergence to Landauer Bound
Patryk Lipka-Bartosik, Martí Perarnau-Llobet
We explore the fundamental limits on thermodynamic irreversibility when cooling a quantum system in the presence of a finite-size reservoir. First, we prove that for any non-intera…
Heat as a witness of quantum properties
A. de Oliveira Junior, Jonatan Bohr Brask, Patryk Lipka-Bartosik
We present a new approach for witnessing quantum resources, such as entanglement and coherence, based on heat generation. Inspired by Maxwell's demon, we ask what the optimal heat…
Finite-size catalysis in quantum resource theories
Patryk Lipka-Bartosik, Kamil Korzekwa
Quantum catalysis, the ability to enable previously impossible transformations by using auxiliary systems without degrading them, has emerged as a powerful tool in various resource…
Efficiently Cooling Quantum Systems with Finite Resources: Insights from Thermodynamic Geometry
Philip Taranto, Patryk Lipka-Bartosik, Nayeli A. Rodríguez-Briones +4
Landauer's limit on heat dissipation during information erasure is critical as devices shrink, requiring optimal pure-state preparation to minimise errors. However, Nernst's third…
Designing optimal protocols in Bayesian quantum parameter estimation with higher-order operations
Jessica Bavaresco, Patryk Lipka-Bartosik, Pavel Sekatski +1
Using quantum systems as sensors or probes has been shown to greatly improve the precision of parameter estimation by exploiting unique quantum features such as entanglement. A maj…
Thermodynamic Computing via Autonomous Quantum Thermal Machines
Patryk Lipka-Bartosik, Martí Perarnau-Llobet, Nicolas Brunner
We develop a physics-based model for classical computation based on autonomous quantum thermal machines. These machines consist of few interacting quantum bits (qubits) connected t…
Fundamental limits on anomalous energy flows in correlated quantum systems
Patryk Lipka-Bartosik, Giovanni Francesco Diotallevi, Pharnam Bakhshinezhad
In classical thermodynamics energy always flows from the hotter system to the colder one. However, if these systems are initially correlated, the energy flow can reverse, making th…
Catalysis in Quantum Information Theory
Patryk Lipka-Bartosik, Henrik Wilming, Nelly H. Y. Ng
Catalysts open up new reaction pathways that can speed up chemical reactions while not consuming the catalyst. A similar phenomenon has been discovered in quantum information scien…

The network scenario offers interesting new perspectives on the phenomenon of quantum nonlocality. Notably, when considering networks with independent sources, it is possible to de…
Operational definition of the temperature of a quantum state
Patryk Lipka-Bartosik, Martí Perarnau-Llobet, Nicolas Brunner
Temperature is usually defined for physical systems at thermal equilibrium. Nevertheless one may wonder if it would be possible to attribute a meaningful notion of temperature to a…
Catalytic quantum teleportation and beyond

The operational significance of the quantum resource theory of Buscemi nonlocality
Patryk Lipka-Bartosik, Andrés Ducuara, Tom Purves +1
Although entanglement is necessary for observing nonlocality in a Bell experiment, there are entangled states which can never be used to demonstrate nonlocal correlations. In a sem…
