Nope. Quantum computing requires low temperatures not because of resistance but to maintain coherence.

A room temperature superconductor would, by definition, maintain quantum coherence (of the superconducting order parameter) at room temperature.

That's not what is meant by coherence, what is required in a quantum computer is for multiple qbits to maintain states coherent to each other. Current quantum computers operate in the milikelvin range for a reason, despite superconductors working at 1000x higher temperatures.
