Fine-structure classification of multiqubit entanglement by algebraic geometry
Masoud Gharahi, Stefano Mancini, Giorgio Ottaviani · Physical Review Research · 2020
The authors use algebraic-geometry tools, secant varieties, and l-multilinear ranks, to present an entanglement classification of generic n-qubit pure states under stochastic local operation and classical communication that is based on a finite number of families and subfamilies.
