Production of Entanglement Entropy by Decoherence
M. Merkli, G. P. Berman, R. T. Sayre +2
We examine the dynamics of entanglement entropy of all parts in an open system consisting of a two-level dimer interacting with an environment of oscillators. The dimer-environment…
Non-Demolition Dispersive Measurement of a Superconducting Qubit with a Microstrip SQUID Amplifier
G. P. Berman, D. I. Kamenev, D. Kinion +1
We have studied the possibility of a single-shot non-demolition measurement of a superconducting qubit using a microstrip SQUID amplifier (MSA). The Johnson noise generated by all…
Non-demolition Adiabatic Measurement of the Phase Qubit State
G. P. Berman, A. A. Chumak, D. I. Kamenev +2
An adiabatic method for a single-shot non-demolition measurement of the phase qubit is suggested. The qubit is inductively coupled to a low-frequency resonator, which in turn is co…
Creation of Two-Particle Entanglement in Open Macroscopic Quantum Systems
M. Merkli, G. P. Berman, F. Borgonovi +1
We consider an open quantum system of N not directly interacting spins (qubits) in contact with both local and collective thermal environments. The qubit-environment interactions a…
Application of Resonance Perturbation Theory to Dynamics of Magnetization in Spin Systems Interacting with Local and Collective Bosonic Reservoirs
M. Merkli, G. P. Berman, A. Redondo
We apply our recently developed resonance perturbation theory to describe the dynamics of magnetization in paramagnetic spin systems interacting simultaneously with local and colle…
Resonant Perturbation Theory of Decoherence and Relaxation of Quantum Bits
M. Merkli, G. P. Berman, I. M. Sigal
We describe our recent results on the resonant perturbation theory of decoherence and relaxation for quantum system with many qubits. The approach represents a rigorous analysis of…
