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…
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…
The capacity of the quantum depolarizing channel
C. King
The information carrying capacity of the d-dimensional depolarizing channel is computed. It is shown that this capacity can be achieved by encoding messages as products of pure sta…
Minimal Entropy of States Emerging from Noisy Quantum Channels
C. King, M. B. Ruskai
In this paper, we consider the minimal entropy of qubit states transmitted through two uses of a noisy quantum channel, which is modeled by the action of a completely positive trac…
