proposed for modeling of a cluster of entangled **qubits** that is
exploited as a computation resource in one-way quantum
computation schemes. A **qubit** model has been designed as a
stochastic **oscillator** formed by a pair of coupled limit cycle
**oscillators** with chaotically modulated limit cycle radii and
**frequencies**. The **qubit** simulates the behavior of electric field of
polarized light beam and adequately imitates the states of two-level
quantum system. A cluster of entangled **qubits** can be associated
with a beam of polarized light, light polarization degree being
directly related to cluster entanglement degree. Oscillatory network,
imitating **qubit** cluster, is designed, and system of equations for
network dynamics has been written. The constructions of one-**qubit**
gates are suggested. Changing of cluster entanglement degree caused
by measurements can be exactly calculated.

We illustrate the scheme by an application to Deutsch-s and Grover-s ... Quantum computation using **qubits** made of two component Bose-Einstein condensates (BECs) is analyzed. We construct a general framework for quantum algorithms to be executed using the collective states of the BECs. The use of BECs allows for an increase of energy scales via bosonic enhancement, resulting in two **qubit** gate operations that can be performed at a time reduced by a factor of N, where N is the number of bosons per **qubit**. We illustrate the scheme by an application to Deutsch-s and Grover-s algorithms, and discuss possible experimental implementations. Decoherence effects are analyzed under both general conditions and for the experimental implementation proposed.

In this paper, we present a simple design for digital phase shift control by using a harmonically injection locked **oscillator** (ILO) of 35MHz **frequency**. Phase shifters at high **frequencies** are essential in many communication system applications such as **frequency** synthesis, quadrature signal generation and phase locked loops (PLLs).

A 22.8 GHz analog **frequency** divide-by-3 circuit is presented based on an injection locked **oscillator**. Substrate integrated waveguide (SIW) technology is used to implement the input and output sections of the **frequency** divider circuit. The input SIW section at the gate of the active device permits the introduction of the injection signal at the third harmonic **frequency** of the **oscillator**, while the output section is designed to maximize the DC-RF conversion efficiency of the **oscillator** circuit. A prototype is fabricated presenting a measured DC-RF efficiency of 38.5% at 7.603 GHz output **frequency** with 3.7 dBm output power. An injection locking bandwidth of 301.4 MHz was obtained for a 1.5 dBm input injection signal at 22.8 GHz.

There is a typical dynamical performance associated with every system. **Oscillations** are phenomena inherent to dynamical systems and the analysis of such phenomena is a fundamental issue for understanding the dynamical behavior of a particular system. Knowledge of the system natural modes, **frequencies** and its associated dampingratio, provide valuable information regarding the system performance after being subjected to a disturbance. Due to the operational requirements, topological changes in the transmission network of the electrical power systems are quite common. This causes modification in both **frequency** and damping values of the natural system modes. In the past, normal changes in the operating condition have kicked up undamped power **oscillations** in the Mexican system, thus assessing the damping of critical oscillation modes of the system is of utmost importance. This paper reports on the application of modal analysis and time domain simulations for computing and tracking the most dominant low **frequency** **oscillations**, also known as interarea modes, in the Mexican power system under different operating conditions. As a result, the most influential system variables on the low **frequency** **oscillations** have been identified

In this article, we are dealing with a model consisting of a classical Van der Pol **oscillator** coupled gyroscopically to a linear **oscillator**. The major problem is analyzed. The regular dynamics of the system is considered using analytical methods. In this case, we provide an approximate solution for this system using parameter-expansion method. Also, we find approximate values for **frequencies** of the system. In parameter-expansion method the solution and unknown **frequency** of **oscillation** are expanded in a series by a bookkeeping parameter. By imposing the non-secularity condition at each order in the expansion the method provides different approximations to both the solution and the **frequency** of **oscillation**. One iteration step provides an approximate solution which is valid for the whole solution domain.

Traditionally, the level of the phase noise, transferred from the **oscillator** outputs to the square waves obtained is calculated ignoring the correlations in the **oscillator** phase noise spectrum. In this paper, accurate expressions are derived, taking into account the phase noise mechanisms in the **oscillators**. The phase noise power spectral densities are calculated in both the traditional way and by using the proposed expressions and they are compared. The situations where the proposed expressions can be useful are identified.
