This paper introduces a novel 12-CNOT decomposition for the double qubit excitation operator, marking a significant advancement over existing implementations that utilize 13 CNOTs. The proposed circuit achieves the lowest CNOT count, depth, and total circuit depth compared to previous state-of-the-art designs, enhancing efficiency in quantum gate operations. Additionally, it incorporates only two extra one-qubit gates, maintaining a competitive one-qubit gate count relative to prior work.
Achieving a 12-CNOT decomposition for double qubit excitation could redefine efficiency benchmarks in quantum gate implementations.
Effective implementation of high-level quantum gates is essential for practical quantum computing. To the best of our knowledge, we present the first reported 12-CNOT decomposition of the double qubit excitation operator, improving upon state-of-the-art (SOTA) implementations with 13 CNOTs. Our new circuit has the lowest CNOT count (12), lowest CNOT depth (10), and lowest total circuit depth (16) among all the previous SOTA circuits. Further, we only added 2 extra one-qubit gates compared to the lowest one-qubit gate count (11) among the previous SOTA circuits.
