New Quantum Gates Boost Efficiency

Kole et al. propose dynamic decomposition strategies for multi-controlled Toffoli gates that leverage mid-circuit measurement, classical feedforward, and ancilla-assisted constructions — capabilities increasingly available in modern quantum hardware. By replacing static decomposi…

This paper presents an adaptive Clifford+T decomposition strategy for large multi-controlled Toffoli gates constrained to a single clean ancilla, leveraging 3- and 4-input relative-phase Toffoli gates alongside dynamic circuit techniques. The key contribution is showing that 4-in…
