Self-Dual Maps and Symmetric Bistochastic Matrices
Corey O'Meara, Rajesh Pereira
The H-unistochastic matrices are a special class of symmetric bistochastic matrices obtained by taking the square of the absolute value of each entry of a Hermitian unitary matrix.…
Private Quantum Channels, Conditional Expectations, and Trace Vectors
Amber Church, David W. Kribs, Rajesh Pereira +1
Private quantum channels are the quantum analogue of the classical one-time pad. Conditional expectations and trace vectors are notions that have been part of operator algebra theo…
Trumping and Power Majorization
David W. Kribs, Rajesh Pereira, Sarah Plosker
Majorization is a basic concept in matrix theory that has found applications in numerous settings over the past century. Power majorization is a more specialized notion that has be…
Normal matrix compressions
John Holbrook, Nishan Mudalige, Rajesh Pereira
The recently developed theory of higher--rank numerical ranges originated in problems of error correction in quantum information theory but its mathematical implications now includ…
