  For several decades, the interest of the scientific community in aneutronic
fusion reactions such as proton-Boron fusion has grown because of potential
applications in different fields. Recently, many scientific teams in the world
have worked experimentally on the possibility to trigger proton-Boron fusion
using intense lasers demonstrating an important renewal of interest of this
field. It is now possible to generate ultra-short high intensity laser pulses
at high repetition rate. These pulses also have unique properties that can be
leveraged to produce proton-Boron fusion reactions. In this article, we
investigate the interaction of a high energy attosecond pulse with a solid
proton-Boron target and the associated ion acceleration supported by numerical
simulations. We demonstrate the efficiency of single-cycle attosecond pulses in
comparison to multi-cycle attosecond pulses in ion acceleration and magnetic
field generation. Using these results we also propose a path to proton-Boron
fusion using high energy attosecond pulses.
