no-go theorem
theorem that states that a particular situation is not physically possible
quantum no-deleting theorem
in quantum information theory, the no-go theorem that, given two copies of a quantum state, one cannot delete only one of the copies
Bell's theorem
in quantum physics, the theorem that locally causal hidden-variable theories cannot reproduce correlations predicted by quantum mechanics
no-broadcast theorem
theorem of quantum information processing
no-hiding theorem
in quantum information theory, the theorem that information lost from a system moves to the subspace of the environment, not in the system–environment correlation
no-communication theorem
no-go theorem in quantum information theory, forbidding some communication during measurement of entangled states
no-cloning theorem
in quantum information theory, the statement that it is impossible to create an independent and identical copy of an arbitrary unknown quantum state
