Effective Hamiltonian in the Problem of a "Central Spin" Coupled to a Spin Environment
Spin quantum interactive microcosmic spin micro rotation magnetic particles low-energy properties model
2014/12/23
We consider here the problem of a "giant spin", with spin quantum number S≫1, interacting with a set of microscopic spins. Interactions between the microscopic spins are ignored. This model desc...
An Alternative to Decoherence by Environment and the Appearance of a Classical World
Decoherence by Environment Appearance Classical World
2010/10/18
We provide an alternative approach to the decoherence-by-environment paradigm in the field of the quantum measurement process and the appearance of a classical world. In contrast to the decoherence ap...
Bright and Dark periods in the Entanglement Dynamics of Interacting Qubits in Contact with the Environment
Bright and Dark periods Entanglement Dynamics Interacting Qubits Environment
2010/4/8
Interaction among the qubits are basis to many quantum logic operations. We report how such inter-qubit interactions can lead to new features, in the form of bright and dark periods in the entanglemen...
We consider non-interacting multi-qubit systems as controllable probes of an environment of defects/impurities modelled as a composite spin-boson environment. The spin-boson environment consists of a ...
