Reply to comment by Hiro-Agonist in Strange material demonstrates exotic quantum state at room temperature. For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. by MistWeaver80

Why can we not use this in some form for quantum computing?

Because it has nothing to do with entanglement, which is a necessity for non-classical computation.

Instead the use case is isolating a two dimensional 'slice' of electrons on the surface of a 3d substrate.

Simply put your question is like asking why can't you use a lathe to make a bolt of cloth: they are fundamentally incompatibile technologies.

Understood, I always thought entanglement was a prerequisite for something to be "quantum", like a standard quantum property.

But to go back to your original post, regular electronics have some shielding, how would you shield electronics at a molecular level from the environment and have them running normally?

But similar effects can be used to transport quantum states that are then later used or have been used in quantum computing. So it still can be useful in quantum computing.
