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

Gilles Buchs, Elaine Wong, Anshumitra Baul +15

Quantitative validation of quantum simulations of dynamical spin response remains challenging because experiment, classical simulation, and quantum simulation do not produce the sa…

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…

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…

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…

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…
