Decoherence, pointer engineering, and quantum state protection.
نویسندگان
چکیده
We present a proposal for protecting states against decoherence, based on the engineering of pointer states. We apply this procedure to the vibrational motion of a trapped ion, and show how to protect qubits, squeezed states, approximate phase eigenstates, and superpositions of coherent states.

Decoherence effects on quantum Fisher information of multi-qubit W states
Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...
متن کاملDecoherence and the (non)emergence of classicality
We prove that, regardless of the Hamiltonian, decoherence of subsystems in a preferred “pointer” basis does not occur for generic quantum states. This shows that the widespread belief that decoherence explains the emergence of classicality is incorrect, and that the emergence of classicality is only to be expected for a very small set of states.

The relevance of decoherence in the context of the quantum to classical transition has been recently recognized [1–3]. The basic idea is that classicality is an emergent property induced in open quantum systems by their environments. Because of the interaction with the environment, the vast majority of states in the Hilbert space of a quantum open system becomes highly unstable to entangling in...

متن کاملDecoherence of a Pointer by a Gas Reservoir
We study the effect of the environment on the process of the measurement of a state of a microscopic spin half system. The measuring apparatus is a heavy particle, whose center of mass coordinates can be considered at the end of the measurement as approximately classical, and thus can be used as a pointer. The state of the pointer, which is the result of its interaction with the spin, is transf...
