  1. Extending linear quantum complexity growth to qubit local circuits and fixed time-independent Hamiltonians

  2. Topological entanglement entropy: rigorous control of finite-size corrections, the entanglement-Hamiltonian (CFT) derivation, microscopic realizations of non-Abelian anyon theories, and higher-dimensional extensions

  3. Confinement-Higgs transition in the random-plaquette Z2 gauge model: Nishimori-line accuracy threshold, anisotropic (p,q) boundary, and the reentrant-versus-vertical phase-boundary question for topological quantum memory

  4. Operators, continuum limits, and gravitational dynamics of quantum-mechanical hair in local discrete gauge theories: the open questions of Preskill and Krauss (1990)

  5. Rigorous accuracy thresholds for fault-tolerant quantum computation against biased noise under realistic (Hamiltonian/coherent) noise, including idle errors and improved bounds

  6. Gauge-invariant, non-perturbative determination of the unbroken gauge symmetry and stable string spectrum in non-Abelian gauge-Higgs systems

  7. Realizing the robust encoding of a qubit in a molecule: realistic noise, quantitative performance, and physical implementation of molecular-rotor quantum error-correcting codes

  8. Reversible quantum networks for asymptotically fast multiplication in Shor's factoring algorithm: construction, scratch space, and crossover

  9. Scalable robustness and asymptotic performance of adiabatic quantum computation: minimum-gap scaling, large-n noise resilience, and interpolation-path design

  10. Domain of validity of the generalized second law and the fate of information in the Russo–Susskind–Thorlacius two-dimensional black hole
