This paper aims to give readers a high-level overview of the different MCX depth reduction techniques that utilize ancilla qubits. We also exhibit a brief analysis of how they would perform under different quantum topological settings. The techniques examined are recursion and v-chain, as they are the most commonly used techniques in the most popular quantum computing libraries, Qiskit. The target audience of this paper is people who do not have intricate mathematical or physics knowledge related to quantum computing.

  1. Practical Fidelity Limits of Toffoli Gates in Superconducting Quantum Processors

    quant-ph 2025-09 reject novelty 3.0 of 10

    Benchmarking a decomposed Toffoli gate on IBM quantum hardware yields 56-64% state fidelities, but the claimed state-dependent error pattern is confounded by using different devices.
