A 100-year-old theory might explain what's wrong with quantum mechanics

Pilot wave theory, developed by Louis de Broglie a century ago, potentially resolves quantum mechanics' paradoxes by describing particles guided by attendant waves rather than existing in superposition.

Large-scale analogue quantum simulation using atom dot arrays - Nature

Analogue quantum simulations are a useful tool for investigating these systems, particularly in regimes in which the applicability of numerical techniques is limited. For different simulator platforms, figures of merit include the electron bandwidth and interaction strength, temperature and the number of simulated lattice sites. Their use is further underscored by the ability to realize distinct lattice geometries, on-site degrees of freedom and by the physical observables that are accessible to experimental measurement.
