Experimental differentiation and extremization with analog quantum circuits
Evan Philip, Julius de Hond, Vytautas Abramavicius +8
Solving and optimizing differential equations (DEs) is ubiquitous in both engineering and fundamental science. The promise of quantum architectures to accelerate scientific computi…
Evaluation of derivatives using approximate generalized parameter shift rule
Vytautas Abramavicius, Evan Philip, Kaonan Micadei +5
Parameter shift rules are instrumental for derivatives estimation in a wide range of quantum algorithms, especially in the context of Quantum Machine Learning. Application of singl…
Extracting Bayesian networks from multiple copies of a quantum system
Kaonan Micadei, Gabriel T. Landi, Eric Lutz
Despite their theoretical importance, dynamic Bayesian networks associated with quantum processes are currently not accessible experimentally. We here describe a general scheme to…
Experimental Validation of Fully Quantum Fluctuation Theorems Using Dynamic Bayesian Networks
Kaonan Micadei, John P. S. Peterson, Alexandre M. Souza +5
Fluctuation theorems are fundamental extensions of the second law of thermodynamics for small systems. Their general validity arbitrarily far from equilibrium makes them invaluable…
Quantum fluctuation theorems beyond two-point measurements
Kaonan Micadei, Gabriel T. Landi, Eric Lutz
We derive detailed and integral quantum fluctuation theorems for heat exchange in a quantum correlated bipartite thermal system using the framework of dynamic Bayesian networks. Co…
Reversing the direction of heat flow using quantum correlations
Kaonan Micadei, John P. S. Peterson, Alexandre M. Souza +6
Heat spontaneously flows from hot to cold in standard thermodynamics. However, the latter theory presupposes the absence of initial correlations between interacting systems. We her…
Experimental rectification of entropy production by a Maxwell's Demon in a quantum system
P. A. Camati, J. P. S. Peterson, T. B. Batalhão +5
Maxwell's demon explores the role of information in physical processes. Employing information about microscopic degrees of freedom, this "intelligent observer" is capable of compen…
Thermodynamic cost of acquiring information
Kaonan Micadei, Roberto M. Serra, Lucas C. Celeri
Connections between information theory and thermodynamics have proven to be very useful to establish bounding limits for physical processes. Ideas such as Landauer's erasure princi…
