Scott Aaronson, Yosi Atia, Leonard Susskind#### On the Hardness of Detecting Macroscopic Superpositions

Scott Aaronson, Yosi Atia, Leonard Susskind

When is decoherence "effectively irreversible"? Here we examine this central question of quantum foundations using the tools of quantum computational complexity. We prove that, if one had a quantum circuit to determine if a system was in an equal superposition of two orthogonal states (for example, the $|$Alive$\rangle$ and $|$Dead$\rangle$ ... more >>>
