Quantum uncertainty of optical coherence
Martti Hanhisalo, Mohammad Sajjad Mirmoosa, Tero Setälä +2
Light is known to exhibit quantum uncertainty in terms of its amplitude, phase, and polarization. However, quantum uncertainty related to coherence, which is also a fundamental phy…
Quantum thermodynamics as a gauge theory
Gabriel Fernandez Ferrari, Łukasz Rudnicki, Lucas Chibebe Céleri
Thermodynamics is based on a coarse-grained approach, from which its fundamental variables emerge, effectively erasing the complicate details of the microscopic dynamics within a m…
Entropic uncertainty relations for mutually unbiased periodic coarse-grained observables resemble their discrete counterparts
Łukasz Rudnicki, Stephen P. Walborn
One of the most important and useful entropic uncertainty relations concerns a dimensional system and two mutually unbiased measurements. In such a setting, the sum of two info…
Comment on "Fluctuations in Extractable Work Bound the Charging Power of Quantum Batteries"
Stefano Cusumano, Łukasz Rudnicki
In the abstract of~[Phys. Rev. Lett. {\bf 125}, 040601 (2020)] one can read that: [...]{\it to have a nonzero rate of change of the extractable work, the state of t…
Algorithmic approach to Cosmological Coherent State Expectation Values in LQG
Klaus Liegener, Łukasz Rudnicki
In the lattice approach to Loop Quantum Gravity on a fixed graph computations tend to be involved and are rarely analytically manageable. But, when interested in the expectation va…
Stabilizing entanglement in two-mode Gaussian states
Tomasz Linowski, Clemens Gneiting, Łukasz Rudnicki
We analyze the stabilizability of entangled two-mode Gaussian states in three benchmark dissipative models: local damping, dissipators engineered to preserve two-mode squeezed stat…
Bounding the sets of classical and quantum correlations in networks
Alejandro Pozas-Kerstjens, Rafael Rabelo, Łukasz Rudnicki +4
We present a method that allows the study of classical and quantum correlations in networks with causally-independent parties, such as the scenario underlying entanglement swapping…
Mutually Unbiased Coarse-Grained Measurements of Two or More Phase-Space Variables
E. C. Paul, S. P. Walborn, D. S. Tasca +1
Mutual unbiasedness of the eigenstates of phase-space operators-such as position and momentum, or their standard coarse grained versions-exists only in the limiting case of infinit…
Uncertainty-Reality Complementarity and Entropic Uncertainty Relations
Łukasz Rudnicki
Reality of quantum observables, a feature of long-standing interest within foundations of quantum mechanics, has recently been quantified and deeply studied by means of entropic me…
Mutual Unbiasedness in Coarse-grained Continuous Variables
Daniel S. Tasca, Piero Sánchez, Stephen P. Walborn +1
The notion of mutual unbiasedness for coarse-grained measurements of quantum continuous variable systems is considered. It is shown that while the procedure of "standard" coarse gr…
