Quantum/Classical Interface: Fermion Spin
W. E. Baylis, R. Cabrera, D. Keselica
Although intrinsic spin is usually viewed as a purely quantum property with no classical analog, we present evidence here that fermion spin has a classical origin rooted in the geo…
Overcoming the su(2^n) sufficient condition for the coherent control of n-qubit systems
R. Cabrera, C. Rangan, W. E. Baylis
We study quantum systems with even numbers N of levels that are completely state-controlled by unitary transformations generated by Lie algebras isomorphic to sp(N) of dimension N(…
Average Fidelity in n-Qubit systems
R. Cabrera, W. E. Baylis
This letter generalizes the expression for the average fidelity of single qubits, as found by Bowdrey et al., to the case of n qubits. We use a simple algebraic approach with basis…
Control and Representation of n-qubit Quantum Systems
W. E. Baylis, R. Cabrera, C. Rangan
Just as any state of a single qubit or 2-level system can be obtained from any other state by a rotation operator parametrized by three real Euler angles, we show how any state of…
Surprising Symmetries in Relativistic Charge Dynamics
William E. Baylis
The eigenspinor approach uses the classical amplitude of the algebraic Lorentz rotation connecting the lab and rest frames to study the relativistic motion of particles. It suggest…
Angular momentum and the geometrical gauge of localized photon staes
Margaret Hawton, William E. Baylis
Localized photon states have non-zero angular momentum that varies with the non-unique choice of a transverse basis and is changed by gauge transformations of the geometric vector…
