An efficient quantum algorithm for computing -units and its applications
Jean-Francois Biasse, Fang Song
In this paper, we provide details on the proofs of the quantum polynomial time algorithm of Biasse and Song (SODA 16) for computing the -unit group of a number field. This algor…

A note on the security of CSIDH
Jean-François Biasse, Annamaria Iezzi, Michael J. Jacobson
We propose an algorithm for computing an isogeny between two elliptic curves defined over a finite field such that there is an imaginary quadratic order sat…
