Nowadays, reversible logic is one of the most important issue which has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology and optical computing. Reversible logic circuits give less power dissipation as well as distinct output that is assigned for each distinct input. The classical set of gates such as the NAND, AND, NOR, OR, XOR and X...

recently testing of quantum-dot cellular automata (qca) circuits has attracted a lot of attention. in this paper, qca is investigated for testable implementations of reversible logic. to amplify testability in reversible qca circuits, a test method regarding to built in self test technique is developed for detecting all simulated defects. a new reversible qca mux 2×1 design is proposed for the ...

In recent years, Quantum Electronics and Reversible Logic have emerged as a major area of research having applications in low power CMOS circuits, cryptography, optical computing and nanotechnology. The fact that classical logic gates such as AND, OR, XOR etc., barring the NOT gate, cannot predict the input given the output and hence generate heat due to information loss, has given rise to the ...

The optical spectrum of reduced myeloperoxidase (EC 1.11.1.7) displays an unusual red shift of the Soret band which is at 472 nm and the alpha-band which is at 636 nm. The spectral properties of myeloperoxidase can be modified by means of acid treatment. Upon short exposure to acid (pH 1.7) the red-shifted optical absorption spectrum of the reduced enzyme (lambda max at 472 nm) was blue-shifted...

Reversible logic is emerging as an important research area in the recent years due to its ability to reduce the power dissipation, which is the main requirement in low power digital design. Energy dissipation is proportional to the number of bits lost during computation. The reversible circuits do not lose information and can generate unique outputs from specified inputs and vice versa. It has ...

We show that light pulses can be stopped and stored coherently, with an all-optical adiabatic and reversible pulse bandwidth compression process. Such a process overcomes the fundamental bandwidth-delay constraint in optics and can generate arbitrarily small group velocities for any light pulse with a given bandwidth, without any coherent or resonant light-matter interactions. We exhibit this p...
