Correlance and Discordance: Computable Measures of Nonlocal Correlation
Samuel R. Hedemann
We present six new measures of nonlocal correlation for discrete multipartite quantum systems; correlance, statance, probablance, strong discordance, discordance, and diagonal disc…
Optomechanical Entanglement of Remote Microwave Cavities
Samuel R. Hedemann, B. D. Clader
We examine the entanglement properties of a system that represents two driven microwave cavities each optomechanically coupled to two separate driven optical cavities which are con…
X States of the Same Spectrum and Entanglement as All Two-Qubit States
Samuel R. Hedemann
We present an explicit family of two-qubit X states with entanglement-preserving unitary (EPU) equivalence to the set of general states; that is, for any spectrum-entanglement comb…
Explicit Inverse Confluent Vandermonde Matrices with Applications to Exponential Quantum Operators
Samuel R. Hedemann
The Cayley-Hamilton problem of expressing functions of matrices in terms of only their eigenvalues is well-known to simplify to finding the inverse of the confluent Vandermonde mat…
Noise-Resistant Quantum Teleportation, Ansibles, and the No-Projector Theorem
Samuel R. Hedemann
A method is presented for achieving entanglement-free teleportation of a quantum state subject to any quantum noise. We apply this as a light-speed noise-resistant communicator, bu…
Distinguishing Coherent States from Phase-Mixed Coherent States with Only a Variable Beam Splitter and Single-Photon Detector, In Principle
Samuel R. Hedemann
It is generally assumed that on-off detectors with single-photon sensitivity cannot distinguish coherent states from phase-mixed coherent states without some form of quadrature-bas…
