Global adiabatic criterion for fast topological photon transfer in Fock-state lattices
Quantum
Summary
arXiv:2606.03409v1 Announce Type: new Abstract: Topological state transfer in Fock-state lattices has been demonstrated with high speed using sinusoidal profiles of coupling, yet the underlying reason has remained unclear. A global adiabatic criterion (GAC) is developed to bound the infidelity by the mean and variance of the nonadiabatic factor. The GAC reveals that the key to fast transfer is not a constant energy gap but the vanishing nonadiabaticity variance.
Why It Matters
This Quantum development moves quantum capability closer to commercial and national-security relevance. For Singapore, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
