Modifying -qubit controlled- gate to be -qubit Toffoli gate
Jian Leng, Fan Yang, Xiang-Bin Wang
The decomposition for controlled- gate in [Phys. Rev. A, 87, 062318 (2013)] has a shallow circuit depth with no ancilla. Here we modify this decomposition to decompose…

Improving D2p Grover's algorithm to reach performance upper bound under phase noise
Jian Leng, Fan Yang, Xiang-Bin Wang
The original Grover's algorithm has a success probability to output a correct solution, while deterministic Grover's algorithms improve the success probability to 100%. However, th…
