Macroscopic Superposition States in Isolated Quantum Systems
, 2021 For any choice of initial state and weak assumptions about the Hamiltonian, large isolated quantum systems undergoing Schrödinger evolution spend most of their time in macroscopic superposition states.

Macroscopic Superpositions as Quantum Ground States [PDF]
Physical Review Letters, 2017 We study the question of what kind of a macroscopic superposition can(not) naturally exist as a ground state of some gapped local many-body Hamiltonian. We derive an upper bound on the energy gap of an arbitrary physical Hamiltonian provided that its ground state is a superposition of two well-distinguishable macroscopic "semi-classical" states.

Steering-enhanced quantum metrology using superpositions of noisy phase shifts
Physical Review Research, 2023 Quantum steering is an important correlation in quantum information theory. A recent work [Nat. Commun. 12, 2410 (2021)NCAOBW2041-172310.1038/s41467-021-22353-3] showed that quantum steering is also useful for quantum metrology.

, 2023 Lying in the core of the conceptual scheme of current quantum theory, the notion of quantum superposition is a consequence of the quantum-mechanical superposition principle. However, relying on precise but not attainable space or time coordinates, quantum superposition makes little sense physically if we use it to describe or explain experimental ...

Investigating the influence of visualization on student understanding of quantum superposition
, 2015 Visualizations in interactive computer simulations are a powerful tool to help students develop productive mental models, particularly in the case of quantum phenomena that have no classical analogue.

Collapse dynamics and Hilbert-space stochastic processes
Scientific Reports, 2021 Spontaneous collapse models of state vector reduction represent a possible solution to the quantum measurement problem. In the present paper we focus our attention on the Ghirardi–Rimini–Weber (GRW) theory and the corresponding continuous localisation ...
