Resonant delay in a stationary quantum clock: Lifting the threshold mask
Summary
arXiv:2606.02718v1 Announce Type: new Abstract: Quantum transit times have a long history of inequivalent definitions, including phase times, dwell times, and quantum-clock constructions. In this context we revisit the Salecker--Wigner--Peres stationary quantum clock as a phase-sensitive scattering observable, with clock time defined by the energy derivative of the transmission phase shift across the interaction region. For real compactly supported one-dimensional potentials, we show that the raw stationary Peres clock generically contains a universal \(1/\sqrt{E}\) continuum-edge term whose coefficient is fixed by low-energy scattering data.
Why It Matters
This Quantum development moves quantum capability closer to commercial and national-security relevance. For Asia, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
