computing machines require the highest possible dependability in order to provide accurate functionality in aggressive, critical environments. For this purpose, the Embryonics (for embryonic electronics) project explores Nature's structural redundancy mechanisms in digital electronics. It offers a hierarchically reconfigurable framework [4][5][18], whose effectiveness was assessed only for some particular cases [8]. Following the introduction of specialized memory structures [10][13], this paper proposes a more thorough reliability analysis, inspired by faulttolerant quantum computing theory. After adopting the accuracy threshold measure as the main parameter for our qualitative evaluation, the concepts and implementation details about concatenated coding are presented. This technique, also inspired from reliable quantum computing, seems particularly well suited for the multiple-level architecture in Embryonics and allows preserving arbitrary long fault-tolerant computation.

The need for error detection and correction techniques is vital in quantum computation, due to the omnipresent nature of quantum errors. No realistic prospect of an operational quantum computational device may be warranted without such mechanisms. Therefore, the fact that error detecting and correcting techniques have been developed has enhanced the feasibility of a potential quantum computer [15] [18]. This paper presents a methodology for improving the fault tolerance of quantum circuits by using the so-called reconfigurable Quantum Gate Arrays (rQGAs). Our solution reduces the problem of stabilizer coding safe recovery to preserving a given quantum configuration state. As shown in this paper's practical example, the configuration register to be protected has a reduced number of qubits, and the overall dependability attribute [2] - reliability measured by the accuracy threshold [15] - is drastically improved.

This paper proposes an original approach to the reliability analysis for Embryonics (Mange and Tomassini, 1998), by introducing the accuracy threshold measure, borrowed from fault-tolerant quantum computing theory, as one of the main parameters for our qualitative assessment. The validity of this technique is proven by comparison with the classical reliability results; furthermore, it brings new perspectives on designing reliable embryonic memory structures at both the molecular and the cellular levels. Appropriate design principles are provided on both information encoding (concatenated codes) and storage (fault tolerant memory structures).
