The Optimization and Application of 3-Bit Hermitian Gates and Multiple Control Toffoli Gates
IEEE Transactions on Quantum Engineering, 2022 The well-known 3-bit Hermitian gate (a Toffoli gate) has been implemented using Clifford+T circuits. Compared with the Peres gate, its implementation circuit requires more controlled-not (cnot) gates. However, the Peres gate is not Hermitian.
