EarlyCommit: Calibrated Word-by-Word Commitment for Robots Acting Before You Finish Speaking

Muhammad Haris Khan

Human listeners can often identify the intended object several words before an instruction ends. Robots, however, are typically designed to wait until the speaker has finished befo…

A Validation Framework for Quantum Simulation of Spin Dynamics against Inelastic Neutron Scattering and Classical Simulation

Gilles Buchs, Elaine Wong, Anshumitra Baul +16

Establishing quantum simulations as reliable tools for materials research requires quantitative validation against experiments and, where available, classical many-body calculation…

Information Processing in Quantum Thermodynamic Systems: an Autonomous Hamiltonian Approach

Shou-I Tang, Emery Doucet, Akram Touil +2

Extending the quantum formulation of [Phys. Rev. X 3, 041003 (2013)] to a more general setting for studying the thermodynamics of information processing including initial correlati…

Metrological approach to the emergence of classical objectivity

Anthony Kiely, Diana A. Chisholm, Akram Touil +3

We present a precise characterization of the onset of classicality that combines the formalism of quantum Darwinism with the tools from quantum metrology. We show that the quantum…

Observation of Quantum Darwinism and the Origin of Classicality with Superconducting Circuits

Zitian Zhu, Kiera Salice, Akram Touil +9

The transition from quantum to classical behavior is a central question in modern physics. How can we rationalize everyday classical observations from an inherently quantum world?…

Consensus About Classical Reality in a Quantum Universe

Akram Touil, Bin Yan, Wojciech H. Zurek

Quantum Darwinism recognizes that decoherence imprints redundant records of preferred quasi-classical pointer states on the environment. These redundant records are then accessed b…

No-go theorem for environment-assisted invariance in non-unitary dynamics

Akira Sone, Akram Touil, Kenji Maeda +2

We elucidate the requirements for quantum operations that achieve environment-assisted invariance (envariance), a symmetry of entanglement. While envariance has traditionally been…

Quantum information scrambling in two-dimensional Bose-Hubbard lattices

Devjyoti Tripathy, Akram Touil, Bartłomiej Gardas +1

It is a well-understood fact that the transport of excitations throughout a lattice is intimately governed by the underlying structures. Hence, it is only natural to recognize that…

Information scrambling -- a quantum thermodynamic perspective

Akram Touil, Sebastian Deffner

Recent advances in quantum information science have shed light on the intricate dynamics of quantum many-body systems, for which quantum information scrambling is a perfect example…

Pointer states and quantum Darwinism with 2-body interactions

Paul Duruisseau, Akram Touil, Sebastian Deffner

Quantum Darwinism explains the emergence of classical objectivity within a quantum universe. However, to date most research in quantum Darwinism has focused on specific models and…

Branching States as The Emergent Structure of a Quantum Universe

Akram Touil, Fabio Anza, Sebastian Deffner +1

Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insigh…

Redundantly amplified information suppresses quantum correlations in many-body systems

D. Girolami, A. Touil, B. Yan +2

We establish bounds on quantum correlations in many-body systems. They reveal what sort of information about a quantum system can be simultaneously recorded in different parts of i…

Environment-Assisted Shortcuts to Adiabaticity

Akram Touil, Sebastian Deffner

Envariance is a symmetry exhibited by correlated quantum systems. Inspired by this "quantum fact of life," we propose a novel method for shortcuts to adiabaticity which enables the…

Eavesdropping on the Decohering Environment: Quantum Darwinism, Amplification, and the Origin of Objective Classical Reality

Akram Touil, Bin Yan, Davide Girolami +2

"How much information about a system can one extract from a fragment of the environment that decohered it?" is the central question of Qua…

Quantum Euler relation for local measurements

Akram Touil, Kevin Weber, Sebastian Deffner

In classical thermodynamics the Euler relation is an expression for the internal energy as a sum of the products of canonical pairs of extensive and intensive variables. For quantu…

Ergotropy from quantum and classical correlations

Akram Touil, Barış Çakmak, Sebastian Deffner

It is an established fact that quantum coherences have thermodynamic value. The natural question arises, whether other genuine quantum properties such as entanglement can also be e…

Information scrambling vs. decoherence -- two competing sinks for entropy

Akram Touil, Sebastian Deffner

A possible solution of the information paradox can be sought in quantum information scrambling. In this paradigm, it is postulated that all information entering a black hole is rap…

Quantum scrambling and the growth of mutual information

Akram Touil, Sebastian Deffner

Quantum information scrambling refers to the loss of local recoverability of quantum information, which has found widespread attention from high energy physics to quantum computing…
