We report the experimental demonstration of chaotic phase synchronization (CPS) in unidirectionally coupled time-delay systems using electronic circuits. We have also implemented experimentally an efficient methodology for characterizing CPS, namely, the localized sets. Snapshots of the evolution of coupled systems and the sets as observed from the oscilloscope confirming CPS are shown experime...

This paper presents a methodology to describe quantum mechanical states of charge qubits, realized as coupled dots occupied by single electrons, using equivalent electrical circuits. We explain how construct all equations starting from low-level simulations wave functions and interpret the relationship between parameters appearing in resulting model physical system. An efficient obtain 2D is pr...

An important goal of synthetic biology is the rational design and predictable implementation of synthetic gene circuits using standardized and interchangeable parts. However, engineering of complex circuits in mammalian cells is currently limited by the availability of well-characterized and orthogonal transcriptional repressors. Here, we introduce a library of 26 reversible transcription activ...

Superconducting qubits are solid state electrical circuits fabricated using tech5 niques borrowed from conventional integrated circuits. They are based on the 6 Josephson tunnel junction, the only non-dissipative, strongly non-linear circuit ele7 ment available at low temperature. In contrast to microscopic entities such as 8 spins or atoms, they tend to be well coupled to other circuits, which...

Low power, high-speed bus architectures, based on low swing voltage technique, using multithreshold voltage transistors are proposed in this paper. Three different classes of driver/repeater/receiver circuits are introduced. The driver circuits are comprised of high threshold voltage MOSFET transistors, in order to reduce their output swing level voltage. For re-pulling up the low swing voltage...

We report a general phenomenon concerning the effect of noise on phase synchronization in coupled chaotic oscillators: the average phase-synchronization time exhibits a nonmonotonic behavior with the noise amplitude. In particular, we find that the time exhibits a local minimum for relatively small noise amplitude but a local maximum for stronger noise. We provide numerical results, experimenta...

We show that two capacitively coupled Josephson junctions, in the quantum limit, form a simple coupled qubit system with effective coupling controlled by the junction bias currents. We compute numerically the energy levels and wave functions for the system, and show how these may be tuned to make optimal qubits. The dependence of the energy levels on the parameters can be measured spectroscopic...

It is used the Chua circuit to demonstrate the possibility of obtaining synchronization of chaos with numerical simulations of a coupled nonlinear system consisting of two coupled non-identical circuits. Synchronization is demonstrated through a correlation diagram while the dynamic behavior is explained with a bifurcation diagram. One of the circuit has an additional noise source, while to the...

In this paper, an algorithm for the coupled simulation of circuit and piezoelectric laminate devices is presented. A finite element solver for piezoelectric laminates is included in the SPICE framework as a capacitor. The charge of this capacitor is a function of both the terminal voltage and the mechanical strain in the piezoelectric material. The coupled simulator allows simulation of novel m...
