The Race to Quantum Technologies and Quantum Computers (Useful Links)
One of my main research directions in the last decade is quantum information theory and quantum computers. (See this post and this one.) It is therefore a pleasure to report and give many links on the massive efforts carried out these … Continue reading
The Simplex, the Cyclic polytope, the Positroidron, the Amplituhedron, and Beyond
A quick schematic road-map to these new geometric objects. The positroidron can be seen as a cellular structure on the nonnegative Grassmanian – the part of the real Grassmanian G(m,n) which corresponds to m by n matrices with all m by … Continue reading
