Autor: Steven Herbert, Ifan Williams, Roland Guichard, Darren Ng

Publikováno v: IEEE Transactions on Quantum Engineering, Vol 5, Pp 1-23 (2024)

In this article, based on some simple and reasonable assumptions, we derive a Gaussian noise model for quantum amplitude estimation. We provide results from quantum amplitude estimation run on various IBM superconducting quantum computers and on Quan

The performance and scalability of macroscopic assignment and simulation software limits the quantity, scale and complexity of simulations of transport networks that are used to aid the planning, design and operation of transport systems. Through the

In perturbation conditions, above-threshold ionization spectra produced in the interaction of atoms with femtosecond short-wavelength laser pulses are well predicted by a theoretical approach called CV2-, which is based on Coulomb–Volkov-type state

International audience; We present characterizations of the attosecond pulse train produced in the high harmonic generation (HHG) from SF 6 molecules irradiated by a strong pulsed laser field at 800 nm. At harmonic order 17, we observe a minimum in t

Saturation of the nonlinear refractive index in atomic gases

Publikováno v: Physical Review A. 87

Motivated by the ongoing controversy over the origin of the nonlinear index saturation and subsequent intensity clamping in femtosecond filaments, we study the atomic nonlinear polarization induced by high-intensity ultrashort laser pulses in hydroge
