Comments on "sub-KBT micro-electromechanical irreversible logic gate"
In a recent article, Nature Communications 7 (2016) 12068, the authors claimed that they demonstrated sub-kT energy dissipation at elementary logic operations. However, the argumentation is invalid because it neglects the dominant source of energy dissipation, namely, the charging energy of the capacitance of the input electrode, which totally dissipates during the full (0-1-0) cycle of logic v...
متن کاملSub-kBT micro-electromechanical irreversible logic gate
In modern computers, computation is performed by assembling together sets of logic gates. Popular gates like AND, OR and XOR, processing two logic inputs and yielding one logic output, are often addressed as irreversible logic gates, where the sole knowledge of the output logic value is not sufficient to infer the logic value of the two inputs. Such gates are usually believed to be bounded to d...
متن کاملComments on Predicative Logic
The syntax of intuitionistic propositional second-order logic PSOLi consists of a set of propositional constants P , Q, R, etc, a denumerable set of propositional variables F , G, H, etc, together with the primitive logical signs of the conditional and the universal propositional quantifier, and ponctuation signs (parenthesis). The formulas of PSOLi are the smallest class of expressions of the ...
متن کاملA discussion about LNG Experiment: Irreversible or Reversible Generation of the Or Logic Gate?
In a recent paper M. Lopez-Suarez, I. Neri, and L. Gammaitoni (LNG) present a concrete realization of the Boolean Or irreversible gate, but contrary to the standard Landauer principle, with an arbitrary small dissipation of energy. A Popperian good falsification! In this paper we discuss a theoretical description of the LNG gate which is indeed a 3in/3out self–reversible realization of the invo...
متن کاملEffect of Electric Potential Distribution on Electromechanical Behavior of a Piezoelectrically Sandwiched Micro-Beam
The paper deals with the mechanical behavior of a micro-beam bonded with two piezoelectric layers. The micro-beam is suspended over a fixed substrate and undergoes the both piezoelectric and electrostatic actuation. The piezoelectric layers are poled through the thickness and equipped with surface electrodes. The equation governing the micro-beam deflection under electrostatic pressure is deriv...
