Effect of laser pulse shaping parameters on the fidelity of quantum logic gates

Abstract: The effect of varying parameters specific to laser pulse shaping instruments on resulting fidelities for the ACNOT(1), NOT(2), and Hadamard(2) quantum logic gates are studied for the diatomic molecule (12)C(16)O. These parameters include varying the frequency resolution, adjusting the number of frequency components and also varying the amplitude and phase at each frequency component. A time domain analytic form of the original discretized frequency domain laser pulse function is derived, providing a useful mea… Show more

“…Recently, Zaari and Brown studied the effect of laser pulse shaping parameters about the fidelity in realizing the quantum gates. They proved that the amplitude variation and frequency resolution plays the important role in the fidelity [34]. We will explore the impacts of those two coefficients in the future work.…”

“…Knowledge of these signs is, however, vital in many applications. 4,5,6,7,8,9,10,11 For example, in the short pulse productions of wave packets, 4,5 the fluorescence signal is composed of the beatings between many transitions whose signs fundamentally affect the observations. We have previously shown 12,13,14 that given the squares of the TDMs, we are able to derive the TDMs amplitudes and perform a point-by-point construction of the excited Born−Oppenheimer potential energy surface (PES) from which the emission occurs.…”

“…Manipulation and control of quantum states are substantial issues in various fields of atomic physics including quantum information [1][2][3], atomic clocks [4], spectroscopy [5], surface plasmon polariton [6,7], chemical reactions [8], Bose-Einstein condensate [9], collision dynamics [10], laser cooling [11], interferometry [12], and magnetic resonance [13]. Among these applications, much attention is focused on keeping these quantum systems at high fidelity and robustness [14][15][16].…”
