Query: Optimization of Circuits for IBM's five-qubit Quantum Computers   IBM has made several quantum computers available to researchers around the
world via cloud services. Two architectures with five qubits, one with 16, and
one with 20 qubits are available to run experiments. The IBM architectures
implement gates from the Clifford+T gate library. However, each architecture
only implements a subset of the possible CNOT gates. In this paper, we show how
Clifford+T circuits can efficiently be mapped into the two IBM quantum
computers with 5 qubits. We further present an algorithm and a set of circuit
identities that may be used to optimize the Clifford+T circuits in terms of
gate count and number of levels. It is further shown that the optimized
circuits can considerably reduce the gate count and number of levels and thus
produce results with better fidelity.
