Switching scheme boosts links between quantum computer modules
Researchers have proposed an optical interconnect design that uses a switching scheme to strengthen connections between separate quantum computing modules. The approach is intended to address scaling limits imposed by planar chip layouts or fixed qubit counts. The abstract does not specify a qubit platform or report performance figures.

Within two years, this switching scheme could be adapted by modular quantum computing vendors to link small cryogenic or ion-trap modules into larger logical processors without waiting for monolithic fabrication improvements.
Optical interconnects are already used in some modular architectures, and a switching scheme that improves link efficiency directly attacks a known bottleneck. If the design is compatible with existing photonic packaging, it can be tested on current hardware generations.
