Sub-Cubic Quantum Gate Synthesis via Stochastic Commutator Decomposition

Yevgen Kotukh

We present Stochastic Commutator Synthesis, a hybrid quantum gate compilation framework that integrates Kuperberg's sub-cubic Solovay-Kitaev exponent c near 1.44042 with the error-…

Secured Encryption scheme based on the Ree groups

Gennady Khalimov, Yevgen Kotukh

An improved design of a cryptosystem based on small Ree groups is proposed. We have changed the encryption algorithm and propose to use a logarithmic signature for the entire Ree g…
