Positive P-Representations of the Thermal Operator from Quantum Control Theory
John A. Sidles
A positive P-representation for the spin-j thermal density matrix is given in closed form. The representation is constructed by regarding the wave function as the internal state of…
Path Integrals over Measurement Amplitudes: Practical Quantum Foundations for Signal Processing and Control
J. A. Sidles
It is shown that classical control diagrams can be mapped one-to-one onto quantum path integrals over measurement amplitudes. To show the practical utility of this method, exact cl…
Fluctuation, Dissipation, and Entanglement: the Classical and Quantum Theory of Thermal Magnetic Noise
J. A. Sidles, J. L. Garbini, W. M. Dougherty +1
A general theory of thermal magnetic fluctuations near conductive materials is developed; such fluctuations are the magnetic analog of Johnson noise. For realistic experiments in q…
Zero-Temperature Casimir Fluctuations and the Limits of Force Microscope Sensitivity
John A. Sidles
It is predicted that in force microscopy the quantum fluctuations responsible for the Casimir force can be directly observed as temperature-independent force fluctuations having sp…
The AC Stark, Stern-Gerlach, and Quantum Zeno Effects in Interferometric Qubit Readout
J. A. Sidles
This article describes the AC Stark, Stern-Gerlach, and Quantum Zeno effects as they are manifested during continuous interferometric measurement of a two-state quantum system (qub…
