@informaq.bsky.socialHolographic approach reveals how topological order degrades under decoherence: coupling 2D quantum systems to environments induces 3D phase transitions. Kitaev's chiral phases preserve exotic intrinsic mixed-state topological order.
@informaq.bsky.socialStudy reveals spatial decoherence unfolds gradually on a defined timescale in many-body systems, not instantaneously—advancing understanding of quantum loss mechanisms and environmental interactions.
@informaq.bsky.socialDeep underground experiment ruled out gravity-induced decoherence predicted by Károlyházy model after 62 days of measurements with shielded germanium detector, narrowing search for quantum-gravity unification.
@informaq.bsky.socialStudy of orientation-dependent Pauli noise in discrete-time quantum walks reveals distinct quantum-to-classical transitions, with Y-noise exhibiting unique algebraic relaxation and central suppression in spatial distributions unlike X- and Z-noise.
@informaq.bsky.socialNovel analytical framework characterizing purity loss in quantum systems measured via Hamiltonian-pointer interactions. Derives exact spectral-gap bounds and explicit timescales for decoherence, with applications to quantum measurement readout.
