"Noise can sometimes benefit the detection of weak signals [1]. Researchers have dubbed this couterintuitive phenomenon as the stochastic resonance (SR) effect [2]. ... The SR noise benefit occurs in a diverse range of sys- tems from neurons [3] to superconducting quantum interference devices [4] to crayfish [5]. The SR noise benefit also occurs in the quantum regime with unique quantum effects such as squeezed light [6, 7], tunneling [8], quantum jumps in a micromaser [9], electron shelving [10], and entanglement [11]. All the aforementioned classical and quantum scenarios for SR involve the detection of weak signals. ... by constructing a modified teleportation protocol in which classical noise enhances the fidelity of quantum teleportation"
