Wavelength and intensity dependence of multiple forward scattering at above-threshold ionization in mid-infrared strong laser fields
Wavelength intensity forward scattering above-threshold ionization
2010/11/16
The nonperturbative role of multiple forward scattering for Coulomb focusing in mid-infrared laser fields and its dependence on a laser intensity and wavelength are investigated for low-energy photoe...
Reverse Test and Characterization of Quantum Relative Entropy
Reverse Test Characterization Quantum Relative Entropy
2010/10/29
The aim of the present paper is to give axiomatic characterization of quantum relative entropy utilizing resource conversion scenario. We consider two sets of axioms: non-asymptotic and asymptotic. In...
Wiesner's quantum money [5] is a simple, information-theoretically secure quantum cryptographic protocol. In his protocol, a mint issues quantum bills and anyone can query the mint to authenticate a ...
The Amplified Quantum Fourier Transform (Amplified-QFT)
Quantum Fourier Transform Amplitude Amplification Oracle
2010/10/29
In this paper we show how to use Grover's algorithm to amplify and enhance the period finding capability of the quantum Fourier Transform (QFT). In particular we create a quantum algorithm called the...
