Quanto: Optimizing Quantum Circuits with Automatic Generation of Circuit Identities

Understand

Existing quantum compilers focus on mapping a logical quantum circuit to a quantum device and its native quantum gates.

• Only simple circuit identities are used to optimize the quantum circuit during the compilation process.
• This approach misses more complex circuit identities, which could be used to optimize the quantum circuit further.
• We propose Quanto, the first quantum optimizer that automatically generates circuit identities.
