Phase transition of environment for overcoming the trade-off between controlling and protecting quantum states

Precursory Research for Embryonic Science and Technology (PRESTO), Japan Science and Technology Agency
October 2017– September 2021

Oct 2017– Sept 2021: In order to push the frontier of quantum technologies into the real societies, we try to establish a strategy for overcoming the trade-off between controlling and protecting quantum states. In contrast to the conventional way relying on the suppression of decoherence sources in fabrication processes, we artificially cause a phase transition of environment incorporating the decoherence sources, which are expected to be pinned by a spontaneously appeared field and an engineered energy gap in the environment, while keeping quantum-bits unchanged.
