\begin{abstract}
|
|
Quantum Key Distribution (QKD) is a promising technology for the establishment of shared secret keys at a distance
|
|
that relies on quantum physical laws of nature instead of cryptographic computational assumptions. Currently, a
|
|
severe trade-off between bit rate and distance limits practical applications of QKD to distances of several hundred
|
|
kilometers and less since physically, QKD signals cannot be amplified. Although in theory, QKD signals can be
|
|
repeated to extend their reach, such repeaters require powerful quantum computing primitives and no practical
|
|
implementations exist yet. Current practice for long-range QKD networks use physically trusted repeater stations
|
|
that convert QKD signals to (insecure) classical signals and back.
|
|
|
|
In this paper, we outline an application of the IHSM approach first proposed by \textcite{gotteCantTouchThis2022}
|
|
to QKD that bootstraps a physically secure repeater node. At the core of our proposal is an optical passthrough
|
|
connecting multiple optical fibers from the payload through the mesh to the outside world. Our design is both
|
|
low-cost and scalable.
