- We provide a rigorous mathematical proof and numerical evidence that our energy landscape control schemes for quantum devices are optimally robust at optimal fidelity performance, surpassing hard limits in classical control. This establishes a theory of robust quantum control, which led to a US-UK Advanced Studies Institute with the University of Southern California (NSF, 165K USD: https://www.nsf.gov/awardsearch/showAward?AWD_ID=1829078). Experimental studies verifying the capabilities and performance limits of quantum devices are being pursued with Aarhus University (Jacob Sherson’s group). Robust operation is essential for realising practical quantum devices. Moreover, our results provide deep insights into the emergence of classical behaviour under decoherence.
