Entanglement is inseparable state |ψ>=[itex]\Sigma[/itex][itex]\Sigma[/itex]c(n1,n2)|n1n2> but for decoherence where system and environment coupling |ψ>(s,e)=[itex]\Sigma[/itex]c|s>[itex]\otimes[/itex]|e> which is normal tensor product, can we still say entanglement cause decoherece or just the tensor product between system and environment?(adsbygoogle = window.adsbygoogle || []).push({});
