  • Recently, spontaneous symmetry breaking was reported in 1D and 2D lattices with long-range interactions on analogue quantum simulators. Here, using a digital quantum annealing algorithm, Hu et al. observe this effect in a tree-like superconducting qubit lattice with short-range interactions at zero temperature.

  • Quasiparticles, or broken Cooper pairs, are a major source of decoherence in superconducting qubits but their origin is debated. Pan et al. confirm the dominant mechanism due to photon absorption in the Josephson junction and demonstrate mitigation strategies based on tuning of the qubit geometry.
