Original Kurzfassung:
The quest of achieving higher computing performance
is driving the research on
quantum computing, which is
reporting new milestones almost on
a daily basis. For practical
quantum circuit design, fault tolerance is an
essential condition.
This is achieved by mapping the
target functions into the
Clifford+T group of elementary
quantum gates. Furthermore,
the application of error-correcting codes in
quantum circuits requiresthe
quantum gates to be formed between adjacent
Qubits. In this work,
we improve the state-of-the-art
quantum circuit design by addressing both
of the above challenges. First,
we propose a novel mapping of Multiple-Control Toffoli (MCT)
gates to Clifford+T group gates, which achieves lower gate count compared to earlier work.
Secondly, we show a generic way to
convert any Clifford+T circuit into a nearest neighbor one. We
validate the efficacy of our approach with detailed experimental studies.
