The hyperlink representation of entanglement and the inclusion-exclusion principle
Silvia N. Santalla, Sudipto Singha Roy, Germán Sierra +1
The entanglement entropy (EE) of any bipartition of a pure state can be approximately expressed as a sum of entanglement links (ELs). In this work, we introduce their exact extensi…
Quantum Complexity in Rule-Based Constrained Many-Body Models: Scars, Fragmentation, and Chaos
Arkaprava Sil, Sudipto Singha Roy
Kinetic constraints in quantum many-body systems strongly restrict the accessible Hilbert space, giving rise to highly nontrivial dynamical behavior. In recent years, such systems…
Landauer Principle and Thermodynamics of Computation
Pritam Chattopadhyay, Avijit Misra, Tanmoy Pandit +1
According to the Landauer principle, any logically irreversible process accompanies entropy production, which results in heat dissipation in the environment. Erasing of information…
A Complete Characterization of Passive Unitary Normalizable (PUN) Gaussian States
Tiju Cherian John, Hemant K. Mishra, Saikat Guha
We provide a complete characterization of the class of multimode quantum Gaussian states that can be reduced to a tensor product of thermal states using only a passive unitary oper…
Converse bounds for quantum hypothesis exclusion: A divergence-radius approach
Kaiyuan Ji, Hemant K. Mishra, Milán Mosonyi +1
Hypothesis exclusion is an information-theoretic task in which an experimenter aims at ruling out a false hypothesis from a finite set of known candidates, and an error occurs if a…
Sensing multiatom networks in cavities via photon-induced excitation resonance
Pritam Chattopadhyay, Avijit Misra, Saikat Sur +2
We explore the distribution in space and time of a single-photon excitation shared by a network of dipole-dipole interacting atoms that are also coupled to a common photonic field…
