Phase-Programmable Free Electron Quantum States in Synthetic Momentum Space
Alatz Alvarez-Ahedo, Miriam Lazo, Tian-Niu Xu +3
Light-electron interactions generate synthetic momentum-space dynamics that can be used to engineer free electron quantum states. Here we develop coherent control protocols in whic…
Squeezing-Enhanced Rotational Doppler Metrology
Javier Navarro, Mateo Casariego, Gabriel Molina-Terriza +2
A rotating surface can induce a frequency shift in incident light by changing its angular momentum, a phenomenon known as the rotational Doppler effect. This effect provides a mean…
On super additivity of Fisher information in fully Gaussian metrology
Javier Navarro, Simon Morelli, Mikel Sanz +1
Famously, the quantum Fisher information -- the maximum Fisher information over all physical measurements -- is additive for independent copies of a system and the optimal measurem…
Quantum Algorithm for Local-Volatility Option Pricing via the Kolmogorov Equation
Nikita Guseynov, Mikel Sanz, Ãngel RodrÃguez-Rozas +2
The solution of option-pricing problems may turn out to be computationally demanding due to non-linear and path-dependent payoffs, the high dimensionality arising from multiple und…
Ultrafast Stern-Gerlach and Anomalous Bragg Diffraction Regimes of Low-energy Free Electron Interaction with Light
Yongcheng Ding, Zirui Zhao, Bin Zhang +3
Recent advances in photon-induced near-field electron microscopy (PINEM) have significantly impacted allied disciplines such as laser-driven accelerators and free electron radiatio…
