Universality and Dynamical Inequivalence in Isospectral Non-Hermitian Anderson Transitions

Aziz Hasan, Anant Vijay Varma, Namit Anand +1

The Hatano Nelson paradigm establishes that extensive bulk nonreciprocity can destabilize Anderson localization via an imaginary gauge flux. Here, we demonstrate that extensive non…

Simulation of quantum optics by coherent state decomposition

Jeffrey Marshall, Namit Anand

We introduce a framework for simulating quantum optics by decomposing the system into a finite rank (number of terms) superposition of coherent states. This allows us to define a r…

Scrambling and operator entanglement in local non-Hermitian quantum systems

Brian Barch, Namit Anand, Jeffrey Marshall +2

The breakdown of Lieb-Robinson bounds in local, non-Hermitian quantum systems opens up the possibility for a rich landscape of quantum many-body phenomenology. We elucidate this by…

Scrambling of Algebras in Open Quantum Systems

Faidon Andreadakis, Namit Anand, Paolo Zanardi

Many quantitative approaches to the dynamical scrambling of information in quantum systems involve the study of out-of-time-ordered correlators (OTOCs). In this paper, we introduce…

Information Scrambling and Chaos in Open Quantum Systems

Paolo Zanardi, Namit Anand

Out-of-time-ordered correlators (OTOCs) have been extensively used over the last few years to study information scrambling and quantum chaos in many-body systems. In this paper, we…

Quantum coherence as a signature of chaos

Namit Anand, Georgios Styliaris, Meenu Kumari +1

We establish a rigorous connection between quantum coherence and quantum chaos by employing coherence measures originating from the resource theory framework as a diagnostic tool f…

Information Scrambling over Bipartitions: Equilibration, Entropy Production, and Typicality

Georgios Styliaris, Namit Anand, Paolo Zanardi

In recent years, the out-of-time-order correlator (OTOC) has emerged as a diagnostic tool for information scrambling in quantum many-body systems. Here, we present exact analytical…

Quantum coherence and the localization transition

Georgios Styliaris, Namit Anand, Lorenzo Campos Venuti +1

A dynamical signature of localization in quantum systems is the absence of transport which is governed by the amount of coherence that configuration space states possess with respe…

Quantifying non-Markovianity: a quantum resource-theoretic approach

Namit Anand, Todd A. Brun

The quantification and characterization of non-Markovian dynamics in quantum systems is an essential endeavor both for the theory of open quantum systems and for a deeper understan…

Demonstration of fidelity improvement using dynamical decoupling with superconducting qubits

Bibek Pokharel, Namit Anand, Benjamin Fortman +1

Quantum computers must be able to function in the presence of decoherence. The simplest strategy for decoherence reduction is dynamical decoupling (DD), which requires no encoding…

Asymmetry and coherence weight of quantum states

Kaifeng Bu, Namit Anand, Uttam Singh

The asymmetry of quantum states is an important resource in quantum information processing tasks such as quantum metrology and quantum communication. In this paper, we introduce th…
