Soft errors induced by radiation, causing anomalies in satellite equipment and spacecrafts, have become one of the most challenging issues that impact the reliability of modern processors even in ground-level applications. In this work, we investigate the feasibility of using ARM Cortex-R4 CPU for space and avionics applications. We create a single-event upset and transient tolerant variant Cor...

In this paper we show how the fault–tolerant error correction scheme recently proposed by DiVincenzo and Shor may be improved. Our scheme, unlike the earlier one, can also deal with a single error that might occur during the gate operations that are required for the implementation of the error correction and not only in–between the gates and hence presents an improvement towards enabling error ...

A new circuit technique, referred to as the twin-transistor technique, for increasing the noise immunity of dynamic logic circuits is presented. This technique makes dynamic logic gates more tolerant to noise appearing at the gate inputs. A multiply-accumulate circuit has been designed and fabricated using a 0.35pm process to veri f y this technique. Experimental results indicate that the twin-...

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...

Quantum computation based on nonadiabatic geometric phases has attracted a broad range of interests, due to its fast manipulation and inherent noise resistance. However, it is limited some special evolution paths, the gate-times are typically longer than conventional dynamical gates, resulting in weakening robustness more infidelities implemented gates. Here, we propose path-optimized scheme fo...

Nonadiabatic geometric quantum computation is dedicated to the realization of high-fidelity and robust gates, which are necessary for fault-tolerant computation. However, it limited by cyclic mutative evolution path, usually requires longer gate-time abrupt pulse control, weakening gate performance. Here, we propose a scheme realize gates with noncyclic nonadiabatic via invariant-based shortcut...

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...

Quantum computation based on geometric phase is generally believed to be more robust against certain errors or noises than the conventional dynamical strategy. However, gate error caused by decoherence effect inevitable, and thus faster operations are highly desired. Here, we propose a nonadiabatic holonomic quantum (NHQC) scheme with detuned interactions $\Delta$-type three-level system, which...
