How does quantum coherence enable superfluid helium to exhibit macroscopic quantum tunneling, and why is this phenomenon not observed in classical fluids? What role does the collective wavefunction play in allowing superfluid helium to bypass energy barriers, and how does temperature influence this behavior? How can macroscopic quantum tunneling in superfluid helium be harnessed to develop ultra-sensitive quantum sensors or precision measurement technologies?
