چکیده
The simplest non-dissipative 2-level atom system, a qubit, excited by train of resonant n-Gaussian laser pulses is investigated. This concerns examination the averaged atomic variables, intensity-intensity correlation function, and transient fluorescent radiation. Analytical formulas for above expressions are obtained. Computational results show that spectra with initial ground coherent states exhibit asymmetric Mollow structure dip structure, dense oscillation, narrowing, depends on pulse number (n), repetition time (τR), observed time.

Qubit lattice coherence induced by electromagnetic pulses in superconducting metamaterials
Quantum bits (qubits) are at the heart of quantum information processing schemes. Currently, solid-state qubits, and in particular the superconducting ones, seem to satisfy the requirements for being the building blocks of viable quantum computers, since they exhibit relatively long coherence times, extremely low dissipation, and scalability. The possibility of achieving quantum coherence in ma...
متن کاملAn Approximation of Gaussian Pulses
A new technique for generating an approximate replica of Gaussian pulses with good accuracy is proposed and investigated. The Gaussian function is approximated with a waveform that results from the convolution of two triangles. The proposed pulse performs better than other previously reported pulse. The results show good agreement not only for the Gaussian pulse but also for its first and secon...

We study theoretically the quantum dynamics of an electron in the singlyionized double-donor structure in the semiconductor host under the influence of laser pulses whose frequencies are close to structure resonant frequencies. This system can be used as a charge qubit where the logical states are defined by the lowest two energy states of the remaining valence electron localized around one or ...

متن کاملBehaviorally Driven Train Timetable Design
The focus of this thesis is to include the passengers and their behavior inside the train timetable design. This is done through three main objectives: timetable design based on passenger satisfaction, exploitation of hybrid cyclicity and choice based revenue optimization. At first, a new Passenger Centric Train Timetabling Problem is introduced into the planning horizon of the passenger railwa...
