Quantum rotation gates with controlled nonadiabatic evolutions
Quantum gates can be implemented adiabatically and nonadiabatically. Many schemes used at least two sequentially implemented gates to obtain an arbitrary one-qubit gate. Recently, it has been shown that nonadiabatic gates can be realized by single-shot implementation. It has also been shown that...

| description | Quantum gates can be implemented adiabatically and nonadiabatically. Many schemes used at
least two sequentially implemented gates to obtain an arbitrary one-qubit gate. Recently, it has
been shown that nonadiabatic gates can be realized by single-shot implementation. It has also
been shown that quantum gates can be implemented with controlled adiabatic evolutions. In this
paper, we combine the advantage of single-shot implementation with controlled adiabatic
evolutions to obtain controlled nonadiabatic evolutions. We also investigate the robustness to
different types of errors. We find that the fidelity is close to unity for realistic decoherence rates |
