Distinguishing unentangled states with an unentangled measurement
William K. Wootters
In a 1991 paper, Asher Peres and the author theoretically analyzed a set of unentangled bipartite quantum states that could apparently be distinguished better by a global measureme…
Quantum measurements and finite geometry
William K. Wootters
A complete set of mutually unbiased bases for a Hilbert space of dimension N is analogous in some respects to a certain finite geometric structure, namely, an affine plane. Another…
Picturing Qubits in Phase Space
William K. Wootters
Focusing particularly on one-qubit and two-qubit systems, I explain how the quantum state of a system of n qubits can be expressed as a real function--a generalized Wigner function…
High order correlations of generic pure states of finite-dimensional quantum systems are determined by lower order correlations
N. Linden, W. K. Wootters
We show that almost every pure state of multi-party quantum systems (each of whose local Hilbert space has the same dimension) is completely determined by the state's reduced densi…
The power of reduced quantum states
N. Linden, S. Popescu, W. K. Wootters
In a system of n quantum particles, we define a measure of the degree of irreducible n-way correlation, by which we mean the correlation that cannot be accounted for by looking at…
Between entropy and subentropy
Sarah R. Nichols, William K. Wootters
The von Neumann entropy and the subentropy of a mixed quantum state are upper and lower bounds, respectively, on the accessible information of any ensemble consistent with the give…
