memQ Inc.

memQ Inc. is a quantum networking and computing company spun out of the University of Chicago's Pritzker School of Molecular Engineering. Its technical approach uses erbium ions doped into silicon and other solid-state hosts as spin qubits whose optical transitions fall in the telecom band around 1.5 micrometres, allowing qubit states to be linked to standard optical fibre; the company develops nanophotonic cavities and device fabrication to make these emitters addressable and to serve as nodes in a quantum repeater network. It is one of a small group of groups and startups pursuing erbium-in-silicon as a route to fibre-compatible, scalable quantum interconnects, competing with other telecom-wavelength emitter platforms.

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.

OutlookPlausible

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.
