Entangled Differential Tunneling Spectroscopy (EDTS)
Can we develop a unifying experimental methodology based on time-energy entangled photon pairs to directly observe and quantify quantum tunneling in biological systems? EDTS exploits entangled photon pairs to perform simultaneous differential measurements on related protein systems, achieving Heisenberg-limited sensitivity to differences in quantum tunneling landscapes. The methodology provides experimental access to Problems #1, #5, #7, #10, #12, #15, #18, #19, #22, #25, #26, #27, #28, and #29, while its theoretical framework validates the instanton description central to Problem #23. EDTS thus serves as a unifying experimental paradigm connecting a significant subset of the 29 problems to concrete laboratory protocols.
