Description
A fixed-volume comparison of three-dimensional hard-wall quantum confinement is extended to a volume-dependent frequency model for superconducting quantum systems. The equivalent quantum frequency is obtained from the lowest Dirichlet eigenvalue and compared with radio-frequency (RF) scales used in supercon-ducting radio-frequency (SRF) cavities. The calculation separates the Schrödinger confinement scale from the electromagnetic wavelength scale: the quantum frequency follows an inverse two-thirds volume law, whereas a dimensional RF half-wave scale based on L = V¹ᐟ³ follows an inverse one-third volume law. Equating the two frequencies maps MHz-to-GHz SRF operation to submicron-to-micron local confinement lengths, supporting applications to superconducting islands, surface defects, qua-siparticle traps, and cavity-integrated quantum devices.cavity systems.
