Quantum computers must be able to function in the presence of decoherence. The simplest
strategy for decoherence reduction is dynamical decoupling (DD), which requires no …

Quantum technology relies on the utilization of resources, like quantum coherence and
entanglement, which allow quantum information and computation processing. This …

We investigate the phenomenon of bipartite entanglement revivals under purely local
operations in systems subject to local and independent classical noise sources. We explain …

In this paper, we study how to preserve entanglement and nonlocality under dephasing
produced by classical noise with large low-frequency components, such as 1/f noise, using …

We study how dynamical decoupling (DD) pulse sequences can improve the reliability of
quantum computers. We prove upper bounds on the accuracy of DD-protected quantum …

Efficient entanglement preservation in open quantum systems is a crucial scope towards a
reliable exploitation of quantum resources. We address this issue by studying how two-qubit …

A quantum memory or information processing device is subject to the disturbance from its
surrounding environment or the inevitable leakage due to its contact with other systems. To …

A crucial challenge for future quantum technologies is to protect fragile entanglement
against environment-induced decoherence. Here we demonstrate experimentally that …

A field configuration utilizing local static fields and a few continuous-wave driving fields is
constructed to achieve universal (but low-order) protection of two-qubit states. That is, two …

We prove the universality of the generalized QDD N 1 N 2 (quadratic dynamical decoupling)
pulse sequence for near-optimal suppression of general single-qubit decoherence. Earlier …
