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…
Electron Transfer Reactions: Generalized Spin-Boson Approach
Marco Merkli, Gennady Berman, Richard Sayre
We introduce a mathematically rigorous analysis of a generalized spin-boson system for the treatment of a donor-acceptor (reactant-product) quantum system coupled to a thermal quan…
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…
Superradiance Transition in Photosynthetic Light-Harvesting Complexes
G. L. Celardo, F. Borgonovi, M. Merkli +2
We investigate the role of long-lasting quantum coherence in the efficiency of energy transport at room temperature in Fenna-Matthews-Olson photosynthetic complexes. The excitation…
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…
Modeling and Simulation of a Microstrip-SQUID Amplifier
G. P. Berman, O. O. Chumak, D. I. Kamenev +2
Using a simple lumped-circuit model, we numerically study the dependence of the voltage gain and noise on the amplifier's parameters. Linear, quasi-linear, and nonlinear regimes ar…
