" "Our analysis reveals that a minimal finite length of time must elapse in order to achieve a given success rate for distinguishing an initial quantum state from its time-evolved image using an optimal measurement," Whaley said.
The new analysis could help determine the times required for quantum tunneling, such as the tunneling of electrons through the band-gap of a semiconductor or the tunneling of atoms in biological proteins.
It also could be useful in a new field called "weak measurement," which involves tracking small changes in a quantum system, such as entangled qubits in a quantum computer, as the system evolves. No one measurement sees a state that is purely distinct from the previous state. "
Was the time required for quantum tunneling and related phenomenon not able to be calculated before, or was it just being calculated without taking energy-time uncertainty into account?
