From Fermat's last theorem to the quantum computer

摘要: Despite of an active work many researchers in the theory quantum computations, this area still saves some mysterious charm. It is already almost common idea, that maybe fashionable current projects will fade future, but absolutely unpredictable applications appear instead. Why such optimistic predictions are legal here, despite extreme difficulty to suggest each one new promising algorithm or realistic "industrial" application? One reason -- very deep contents area. only extremely unlucky occasion, if a fundamental thing won't supply us with bright insights and serious applications. A sign nontrivial unexpected links between different branches our knowledge. In present paper mentioned link application Weyl quantization computations abstract mathematical constructions born mid XIX century due unsuccessful tries prove Fermat's last theorem.
