memQ compares gate teleportation to circuit cutting for quantum computing
Researchers at memQ Inc. compared two methods for executing quantum circuits across multiple processors: gate teleportation, which uses shared entanglement to transfer gate operations, and circuit cutting, which partitions circuits for separate execution and classical recombination. Their analysis reports that circuit cutting incurs an exponential overhead in the distributed setting.

This could make gate teleportation the preferred primitive for near-term modular quantum processors, pushing hardware teams to invest in entanglement generation between modules rather than relying on circuit cutting.
The reported exponential overhead for circuit cutting means its cost grows rapidly with the number of cuts or circuit width, whereas gate teleportation trades that for entanglement resources already being developed for multi-processor systems; if the comparison holds under realistic noise, it provides a concrete engineering reason to prioritize teleportation-based interconnects.
