Upper bounding the quantum space complexity for computing class group and principal ideal problem

Quantum Physics 2024-05-22 v1

Abstract

In this paper, we calculate the upper bound on quantum space complexity of the quantum algorithms proposed by Biasse and Song (SODA'16) for solving class group computation and the principal ideal problem using the reductions to SS-unit group computation. We follow the approach of Barbulescu and Poulalion (AFRICACRYPT'23) and the framework given by de Boer, Ducas, and Fehr (EUROCRYPT'20) and Eisentr\"{a}ger, Hallgren, Kitaev, and Song (STOC'14).
