Reliably distinguishing states in qutrit channels using one-way LOCC
Christopher King, Daniel Matysiak
We present numerical evidence showing that any three-dimensional subspace of C^3 \otimes C^n has an orthonormal basis which can be reliably distinguished using one-way LOCC, where…
An application of a matrix inequality in quantum information theory
C. King
Quantum information theory has generated several interesting conjectures involving products of completely positive maps on matrix algebras, also known as quantum channels. In parti…
On the existence of a common quadratic Lyapunov function for a rank one difference
Christopher King, Michael Nathanson
Suppose that A and B are real stable matrices, and that their difference A-B is rank one. Then A and B have a common quadratic Lyapunov function if and only if the product AB has n…
New trace norm inequalities for 2 x 2 blocks of diagonal matrices
Christopher King, Michael Nathanson
Several new trace norm inequalities are established for 2n x 2n block matrices, in the special case where the four n x n blocks are diagonal. Some of the inequalities are non-commu…
Inequality for p-norms of positive matrices
C. King
This paper derives an inequality relating the p-norm of a positive 2 x 2 block matrix to the p-norm of the 2 x 2 matrix obtained by replacing each block by its p-norm. The inequali…
Maximal p-norms of entanglement breaking channels
C. King
It shown that when one of the components of a product channel is entanglement breaking, the output state with maximal p-norm is always a product state. This result complements Shor…
