Phase-controlling phononic crystals: realization of acoustic Boolean logic gates.
A phononic crystal (PC) consisting of a square array of cylindrical polyvinylchloride inclusions in air is used to construct a variety of acoustic logic gates. In a certain range of operating frequencies, the PC band structure shows square-like equi-frequency contours centered off the gamma point. This attribute allows for the realization of non-collinear wave and group velocity vectors in the ...

متن کاملRealization of a micrometre-scale spin-wave interferometer
The recent development of spin dynamics opens perspectives for various applications based on spin waves, including logic devices. The first important step in the realization of spin-wave-based logics is the manipulation of spin-wave interference. Here, we present the experimental realization of a micrometre-scale spin-wave interferometer consisting of two parallel spin-wave waveguides. The spin...
متن کاملNMR Quantum Logic Gates for Homonuclear Spin Systems
If NMR systems are to be used as practical quantum computers, the number of coupled spins will need to be so large that it is not feasible to rely on purely heteronuclear spin systems. The implementation of a quantum logic gate imposes certain constraints on the motion of those spins not directly involved in that gate, the so-called “spectator” spins; they must be returned to their initial stat...
متن کاملRealization of Xor and Xnor Gates Using Qca Basic Gates
Quantum dot cellular automata is an emerging nanoelectronic computational architecture which has the potential of faster speed, smaller size and minimum power consumption compared to transistor-based technology. In QCA, binary information are encoded as electronic charge configuration of a cell. Fundamental unit in building of QCA circuit is a QCA cell. A QCA cell is an elementary building bloc...
