Is state tomography an unambiguous test of quantum entanglement?
Niels Grønbech-Jensen, Jeffrey E. Marchese, Matteo Cirillo +1
We provide an alternative interpretation of recently published experimental results that were represented as demonstrating entanglement between two macroscopic quantum Josephson os…
Investigation of resonant and transient phenomena in Josephson junction flux qubits
Jeffrey E. Marchese, Matteo Cirillo, Niels Grønbech-Jensen
We present an analytical and computational study of resonances and transient responses in a classical Josephson junction system. A theoretical basis for resonances in a superconduc…
A Classical Analysis of Capacitively Coupled Superconducting Qubits
James A. Blackburn, Jeffrey E. Marchese, Matteo Cirillo +1
An electrical circuit consisting of two capacitively coupled inductive loops, each interrupted by a Josephson junction, is analyzed through the classical RSCJ model. The same circu…
Classical analogs for Rabi-oscillations, Ramsey-fringes, and spin-echo in Josephson junctions
Jeffrey E. Marchese, Matteo Cirillo, Niels Gronbech-Jensen
We investigate the results of recently published experiments on the quantum behavior of Josephson circuits in terms of the classical modelling based on the resistively and capaciti…
Simulating Ramsey-Type Fringes in a Pulsed Microwave-Driven Classical Josephson Junction
Jeffrey E. Marchese, Matteo Cirillo, Niels Grønbech-Jensen
We present evidence for a close analogy between the nonlinear behavior of a pulsed microwave-driven Josephson junction at low temperature and the experimentally observed behavior o…
Classical analysis of phase-locking transients and Rabi-type oscillations in microwave-driven Josephson junctions
Jeffrey E. Marchese, Matteo Cirillo, Niels Grønbech-Jensen
We present a classical analysis of the transient response of Josephson junctions perturbed by microwaves and thermal fluctuations. The results include a specific low frequency modu…
