There is that, but equally for applications that require no magnetic field, things that are hot have lots of energy. Energetic particles bouncing around everywhere couple to your meticulously-set-up experiment to the environment, destroying your isolated system and removing the quantum effects you're utilizing.
For quantum computing, one of the requirements specified by the di Vincenzo criteria are long decoherence times. Heat seriously reduces those.
