Work and entropy of mixing in isolated quantum systems
Budhaditya Bhattacharjee, Rohit Kishan Ray, Dominik Šafránek
The mixing of two different gases is one of the most common natural phenomena, with applications ranging from CO capture to water purification. Traditionally, mixing is analyze…
Gaussian Open Quantum Dynamics and Isomorphism to Superconformal Symmetry
Ju-Yeon Gyhm, Dario Rosa, Dominik Šafránek
Understanding the Lie algebraic structure of a physical problem often makes it easier to find its solution. In this paper, we focus on the Lie algebra of Gaussian-conserving supero…
Quantifying Information Extraction using Generalized Quantum Measurements
Dominik Šafránek, Juzar Thingna
Observational entropy is interpreted as the uncertainty an observer making measurements associates with a system. So far, properties that make such an interpretation possible rely…
Delayed choice experiments and causality in quantum mechanics
Dominik Šafránek
Although it may seem The Delayed Choice experiments contradict causality and one could construct an experiment which could possibly affect the past, using Many World interpretation…
Quantum Zeno effect in correlated qubits
Dominik Šafránek, Sebastian Deffner
Near term quantum hardware promises to achieve quantum supremacy. From a quantum dynamical point of view, however, it is not unambiguously clear whether fundamental peculiarities o…
Simple expression for the quantum Fisher information matrix
Dominik Šafránek
Quantum Fisher information matrix (QFIM) is a cornerstone of modern quantum metrology and quantum information geometry. Apart from optimal estimation, it finds applications in desc…
Estimation of Gaussian quantum states
Dominik Šafránek
We derive several expressions for the quantum Fisher information matrix (QFIM) for the multi-parameter estimation of multi-mode Gaussian quantum states, the corresponding symmetric…
