yes. that's what decoherence theory is good for.

the measurement problem is still unresolved.
to a physicist trying to explain measurement of quantum spin of single
particles, the fact that decoherence theory can explain why
Schrodinger'
s cat is always either alive or dead (but never both) is of
no use. the formalism still says that the particle is in a superposition
of up/down in between measurements.
