Quantum Group Actions
Tomoyuki Morimae, Keita Xagawa
In quantum cryptography, there could be a new world, Microcrypt, where cryptography is possible but one-way functions (OWFs) do not exist. Although many fundamental primitives and…
An improvement on the versatility of secure multi-party quantum computation protocol: exploitation of triorthogonal quantum error-correcting codes
Petr A. Mishchenko, Keita Xagawa
Secure multi-party quantum computation (MPQC) protocol is a versatile tool that enables error-free distributed quantum computation to a group of mutually distrustful quantum no…
Secure multi-party quantum computation protocol for quantum circuits: the exploitation of triply-even quantum error-correcting codes
Petr A. Mishchenko, Keita Xagawa
Secure multi-party quantum computation (MPQC) protocol is a cryptographic primitive allowing error-free distributed quantum computation to a group of mutually distrustful quant…
Quantum Algorithm for the Multicollision Problem
Akinori Hosoyamada, Yu Sasaki, Seiichiro Tani +1
The current paper presents a new quantum algorithm for finding multicollisions, often denoted by -collisions, where an -collision for a function is a set of dist…
Improved Quantum Multicollision-Finding Algorithm
Akinori Hosoyamada, Yu Sasaki, Seiichiro Tani +1
The current paper improves the number of queries of the previous quantum multi-collision finding algorithms presented by Hosoyamada et al. at Asiacrypt 2017. Let an -collision b…
