It won't have a direct impact on quantum computing. People make qubits out of superconducting materials that become superconducting at 4K or higher, but you have to cool them to around 0.03 K for them to really work well as qubits. See https://en.m.wikipedia.org/wiki/Superconducting_quantum_computing https://en.m.wikipedia.org/wiki/Superconducting_quantum_comp.... But there could very well be indirect applications! This would be very very interesting for the physics community, and surely lead to other new things.
