Controlling the dynamics of entanglement and preventing its disappearance are central requisites for any implementation of quantum information processing. Many solid state qubits are affected by non-Markovian noise, often with 1/f spectrum. Leading order dephasing effects are captured by treating noise in the quasistatic approximation.

Abstract
Controlling the dynamics of entanglement and preventing its disappearance are central requisites for any implementation of quantum information processing. Many solid state qubits are affected by non-Markovian noise, often with 1/f spectrum. Leading order dephasing effects are captured by treating noise in the quasistatic approximation. In this article we investigate dynamical decoupling of a two-qubit gate studying the crossover from Zeno to anti-Zeno entanglement dynamics obtained by varying the sequence parameters.File in questo prodotto:
