DOI: 10.1103/physreva.101.052317
Abstract: High-precision operation of quantum computing systems must be robust to uncertainties and noises in the quantum hardware. In this paper, we show that through a game played between the uncertainties (or noises) and the controls,… read more here.

DOI: 10.1103/physrevlett.129.196801
Abstract: In a low-disorder two-dimensional electron system, when two Landau levels of opposite spin or pseudospin cross at the Fermi level, the dominance of the exchange energy can lead to a ferromagnetic, quantum Hall ground state… read more here.
