Recently, various quantum computing and communication tasks have been implemented using IBM’s superconductivity-based quantum computers. Here, we show that the circuits used in most of those works were not optimized and ...

The architecture of most current quantum computers limits the pairs of qubits that can interact. That is, not all possible CNOT gates are directly available and their implementation requires additional gates. Hence the ...

In order to make the most of the increasing computational power of recently developed quantum computers, it is crucial to perform an efficient mapping of a given quantum circuit that realizes the desired quantum algorithm ...

IBM offers quantum processors for Clifford+T circuits. The only restriction is that not all CNOT gates are implemented and must be substituted with alternate sequences of gates. Each CNOT has its own mapping with a respective ...

With more and more powerful quantum computers becoming available, there is an increasing interest in the efficient mapping of a given quantum circuit to a particular quantum computer (so-called technology mapping). In most ...
