Quantum Amplitude Amplification and Estimation [PDF]
, 2000 Consider a Boolean function $\chi: X \to \{0,1\}$ that partitions set $X$ between its good and bad elements, where $x$ is good if $\chi(x)=1$ and bad otherwise. Consider also a quantum algorithm $\mathcal A$ such that $A |0\rangle= \sum_{x\in X} \alpha_x

Near-single-cycle pulses generated through post-compression on FAB1 laser at ATTOLAB-Orme facility [PDF]
EPJ Web of Conferences, 2021 Generating high-energy few-cycle pulses is key in the study of light-matter interaction in the regime of high field physics. Attosecond science possess the necessary time resolution to study the underlying fundamental processes but requires repetitions ...

Searching for Kerr in the 2PM amplitude [PDF]
Journal of High Energy Physics, 2022 The classical scattering of spinning objects is well described by the spinor-helicity formalism for heavy particles. Using these variables, we derive spurious-pole-free, all-spin opposite-helicity Compton amplitudes (factorizing on physical poles to the ...

High efficiency GHz laser processing with long bursts
International Journal of Extreme Manufacturing, 2023 Bursts of GHz repetition rate pulses involve more ablation mechanisms than single femtosecond pulses. Efficient ablation by GHz laser pulses is a multi-step process, consisting of a first thermal incubation phase, followed by a highly efficient ablation ...

Bessel Beam Dielectrics Cutting with Femtosecond Laser in GHz-Burst Mode
Micromachines, 2023 We report, for the first time to the best of our knowledge, Bessel beam dielectrics cutting with a femtosecond laser in GHz-burst mode. The non-diffractive beam shaping is based on the use of an axicon and allows for cutting glasses up to 1 mm thickness ...
