🔬 The Modular Chiplet Approach

Rigetti bypasses monolithic superconducting manufacturing limits by linking 9-qubit chiplets. The 36-qubit Cepheus-1 system is a stepping stone to a 1,000+ physical qubit target by 2027.

Derivation & Evidence

Rigetti's flagship architecture detailed in the report is a 'Modular Chiplet' system designed to overcome the limitations of a monolithic chip. Specifically, based on the 36-qubit 'Cepheus-1' achievement created by weaving together four 9-qubit chiplets, they aim to expand their physical qubit connected ecosystem to over 1,000 by 2027.
