Image of the Week: Multi-lobe probability density function

Posted by in category: quantum physics

How do 2 random mix Quantum States look like in a graphics image? Pretty.

Today’s Image of the Week comes from a study of The difference between two random mixed quantum states: exact and asymptotic spectral analysis from the Universidad de los Andes and ETH Zürich. In this recent JPhysA paper, José Mejía, Camilo Zapata and Alonso Botero investigate the spectral statistics of the difference of two density matrices, each of which is independently obtained by partially tracing a random bipartite pure quantum state. Their results make it possible to quantify the typical asymptotic distance between the two random mixed states using various distance measures.
