    Creating Entangled States between SQUID Rings and Electromagnetic Fields

    The problem of entangling a SQUID ring inductively coupled to an electromagnetic field mode is considered here. It is demonstrated by solving the time dependent Schrödinger equation that a system with varying ...

    Frequency Down Conversion and Entanglement between Electromagnetic Field Modes via a Mesoscopic SQUID Ring

    In this chapter, and by analogy with Quantum Optics, the properties of SQUID rings (here, a Josephson weak link enclosed by a thick superconducting ring) in the quantum regime are discussed. In particular, the...

    Solutions of the Time-Dependent Schrödinger Equation for a Two-State System

    The statistical properties of a single quantum object and an ensemble of independent such objects are considered in detail for two-level systems. Computer simulations of dynamic zero-point quantum fluctuations...

    Broken Gauge Symmetry in Macroscopic Quantum Circuits

    In this paper, we discuss the macroscopic quantum behavior of simple superconducting circuits. Starting from a Lagrangian for electromagnetic field with broken gauge symmetry, we construct a quantum circuit mo...

    Adding dissipation to the Schrödinger equation from the quantum-potential viewpoint

    We discuss methods of adding dissipation to the Schrödinger equation in light of the quantum-potential interpretation of quantum mechanics. This favors nonlinear equations in general and Kostin's Schrödinger-L...
