粒状铝纳米结Fluxonium量子比特
The authors fabricate a fluxonium circuit using a granular aluminium nanoconstriction to replace the conventional superconductor–insulator–superconductor tunnel junction. Their characterization suggests that this approach will be a useful element in the superconducting qubit toolkit.
双层GaAs中带有中性和带电偶极激子的双密度波
Both bosonic and fermionic collective states can emerge in two-dimensional semiconductor lattices, and mixing these species can further expand the landscape of quantum phases. Here, the authors report Bose–Fermi mixtures of neutral and charged excitons and the emergence of dual-density waves in an electrostatic lattice in a GaAs bilayer.
