The article considers an approach to the modification of manipulative impulse sequences based on Barker codes. It is proposed change structure encoded pulses by duration elementary message, taking into account in duty cycle their repetition while maintaining total average energy. Numerical relations are obtained that determine spectral and temporal parameters for a seven-element pulse sequence,...

Composite pulse sequences, which produce arbitrary predefined rotations of a qubit on the Bloch sphere, are presented. The composite sequences contain up to 17 pulses and can compensate 8 orders experimental errors in amplitude duration. for three basic quantum gates, X (not), Hadamard rotation, derived. Three classes presented: one symmetric two asymmetric. They as their lowest members well-kn...
