Implementation of quantum rotation gates using controlled non-adiabatic evolutions
Quantum gates are the basic building blocks in the quantum circuits model. These gates can be implemented using adiabatic or non adiabatic processes. Adiabatic models can be controlled using auxiliary qubits, whereas non adiabatic models can be simplified by using one single-shot implementation....

| Summary: | Quantum gates are the basic building blocks in the
quantum circuits model. These gates can be implemented using
adiabatic or non adiabatic processes. Adiabatic models can be
controlled using auxiliary qubits, whereas non adiabatic models can
be simplified by using one single-shot implementation. In this paper,
the controlled adiabatic evolutions is combined with the single-shot
implementation to obtain quantum gates with controlled non adiabatic
evolutions. This is an important improvement which can speed the
implementation of quantum gates and reduce the errors due to the
long run in the adiabatic model. The robustness of our scheme to
different types of errors is also investigated.
