Entanglement, Discord and Other Quantum Correlations
Online Presentations | 15 Oct 2019 | Contributor(s): A. Ravi. P. Rau
We will discuss states and operators of two (or more) qubits, and higher dimensional "qudits," from the symmetry groups and algebras pertaining to them. The study of the time evolution of such systems can gain much from the insights and techniques provided by such considerations,...
Kirkman’s Schoolgirls and Quantum Spin Pairs: A 175 Year Long Thread Through Mathematics and Physics
A recreational puzzle posed 175 years ago of 15 schoolgirls to walk three abreast to school for seven days of the week so that no girl sees a friend repeated in her row has links to many areas of mathematics: combinatorics, finite projective geometries, design and coding theory, etc.
