117901-1 We have designed and operated a circuit based on a large-area current-biased Josephson junction whose two lowest energy quantum levels are used to implement a solid-state qubit. The circuit allows measurement of the qubit states with a fidelity of 85% while providing sufficient decoupling from external sources of relaxation and decoherence to allow coherent manipulation of the qubit st...

The paper deals with an approach that automates the computation of frequential characteristics of passive electronic circuit and their associated sensitivities according to all the components of the circuit. This method enables the designer to focus on the physical behavior of the circuit since the modeling and computing tasks are automatically performed without any computer science skills. It ...

Quantum error mitigation is essential for many computing tasks on the noisy quantum computer with a limited number of qubits. In this paper, we propose practical protocol by virtually purifying state without qubit overhead or requiring only one ancilla qubit. dual-state purification, effectively generate purified increased fidelity using erroneous and its dual state, respectively, prepared circ...

This paper presents a new method to approximate and to synthesize fractional systems represented by an explicit transfer function. We first present the distribution of relaxation times function method to approximate this type of function and hopefully to make circuit designers more aware of these advantages when designing fractal system circuits and fractal filters. Computer simulations of the ...

The worldwide diffusion of wireless telecommunication systems opened new perspectives for microwave technologies. High-volume microwave monolithic integrated circuit (MMIC) production became a reality, revolutionizing the approach to microwave-circuit design. Nowadays, this is based on the intensive use of accurate simulation and computer-aided-design (CAD) tools. While scattering parameter mea...

A new design of a hysteresis chaotic circuit is proposed. The simple circuit consists of one capacitor, one inductor, one resistor (negative) and one hysteresis VCVS. Computer simulation results, showing the existence of the double scroll attractor, are reported. Key-Words: Chaos, chaotic circuit, hysteresis, attractor, bifurcation, oscillator 1 This work was supported by the Louisiana BORSF co...

It is well known that Chua’s circuit can exhibit numerous hifiircution phenomena and attractors by tuning one or more circuit parameters. These properties can be used to synthesize sounds with complex freyuenqy spectra ,fbr musical purposes. Investigations of Chua’s circuit for sound synthesis and music composition have produced spec$cutions for tuning multiple circuit parameters to obtain spec...
