Abstract: Error detectable and error correctable coding in Hamming space was researched to discover possible fault tolerant coding constellations, which can implement Boolean logic with fault tolerant property. Basic logic operators of the Boolean algebra were developed to apply fault tolerant coding in the logic circuits. It was shown that application of three-bit fault tolerant codes have pro...

Fault-tolerant control methods have been extensively researched over the last 10 years in the context of chemical process control applications, and provide a natural framework for integrating process monitoring and control aspects in a way that not only fault detection and isolation but also control system reconfiguration is achieved in the event of a process or actuator fault. But almost all t...

This paper proposes the use of processor support for program rollback, as a key primitive to enhance software debugging in production-run environments. We discuss how hardware support for program rollback can be used to characterize bugs on-the-fly, leverage code versioning for performance or reliability, sandbox device drivers, collect monitoring information with very low overhead, support fai...

Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for semiconductor transistor based technologies. A novel fault-tolerant QCA full-adder cell is proposed: This component is simple in structure and suitable for designing fault-tolerant QCA circuits. The redundant version of QCA full-adder cell is powerful in terms of implementing robust digital functions. ...

An architecture for fault tolerant feedback controllers based on the Youla parameterization is suggested. It is shown that the Youla parameterization will give a residual vector directly in connection with the fault diagnosis part of the fault tolerant feedback controller. It turns out that there is a separation between the feedback controller and the fault tolerant part. The closed loop feedba...

This paper presented a novel decentralized fault tolerant control strategy for the control of linear multivariable processes. The multiple model based fault tolerant method is used to improve system performance (under model uncertainty and slow variation) and implement active fault tolerant control. In the mean time, we extended the decentralized unconditional stable control to multiple model c...

Continuous-variable cluster states allow for fault-tolerant measurement-based quantum computing when used in tandem with the Gottesman-Kitaev-Preskill (GKP) encoding of a qubit into bosonic mode. For quad-rail-lattice macronode states, whose construction is defined by fixed, low-depth beam splitter network, we show that Clifford gate and GKP error correction can be simultaneously implemented si...

Abstract The fault-tolerant operation of logical qubits is an important requirement for realizing a universal quantum computer. Spin based on dots have great potential to be scaled large numbers because their compatibility with standard semiconductor manufacturing. Here, we show that error correction code can implemented using four-qubit array in germanium. We demonstrate resonant SWAP gate and...
