A system is fault-tolerant if it maintains some form of correctness in the presence of faults. Fault-tolerant systems are necessary in many application areas of computing, especially where the failure of a computer system may lead to considerable damage. However, the development of fault-tolerant systems is a difficult task and requires rigorous and scientifically sound engineering methodologie...

We investigate the problem of constructing spanners for a given set of points that are tolerant for edge/vertex faults. Let S IRd be a set of n points and let k be an integer number. A k-edge/vertex fault tolerant spanner for S has the property that after the deletion of k arbitrary edges/vertices each pair of points in the remaining graph is still connected by a short path. Recently it was sho...

Fault-tolerant implementation of quantum gates is one preconditions for realizing computation. The platform Rydberg atoms the most promising candidates achieving We propose to implement a controlled-$Z$ gate on where an amplitude-modulated field employed induce antiblockade. Gate robustness against fluctuations in Rydberg-Rydberg interaction can be largely enhanced by adjusting field. Furthermo...

In recent decades, transient faults have become a critical issue in modern electronic devices. Therefore, many fault-tolerant techniques have been proposed to increase system reliability, such as active redundancy, which can be implemented in both space and time dimensions. The main challenge of active redundancy is to introduce the minimal overhead of redundancy and to schedule the tasks. In m...
