123. Search as quantum selforganized process

Giovanna Morigi (Saarland University)

Invited Talk

Efficient retrieval of information is a core operation in the world wide web, is essential for the sustainance of living organism, and is a paradigm for optimization algorithms. Inspired by the food search dynamics of living organisms, we discuss a search on a graph where the dynamics is a selforganized process resulting from the interplay of coherent dynamics and noise. We show that noise can...

82. How Quantum Information Excites Chemists: Optimizing Excited State Orbitals with Tools from Quantum Information Theory

Quantum Information & Computing

Contributed Talk

Accurately computing the electronic energy of molecular reactants and during chemical reactions is the central challenge of quantum chemistry. Unlike mean-field methods such as Hartree-Fock or Kohn-Sham density functional theory, configuration interaction (CI) methods exactly calculate the repulsive interaction between electrons based on a many-particle wave function rather than relying on...

Quantum Information & Computing

Contributed Talk

Quantum computers promise new ways of solving problems that are difficult for classical computers, but their practical realization requires extremely precise control of quantum systems. In this talk, I will introduce the general challenge of controlling quantum devices and explain why reliable quantum operations are essential for scalable quantum computing. I will then present a new approach...

114. Decoherence and Quantum Darwinism in a Scattering Model

Fundamentals of quantum systems

Contributed Talk

In the quantum computation era, the need of controlling the coherence lifetime of open quantum systems has increased considerably, making decoherence a critical topic. Quantum Darwinism (QD), a concept popularized by W. Zurek [1], can be viewed as a special case of decoherence with unique characteristics and can shed some light on the quantum-to-classical transition. In this scenario, nearly...
