Ensuring the correct functioning of quantum error correction (QEC) circuits is crucial to achieve fault tolerance in realistic quantum processors subjected to noise. The first checkpoint for a fully operational QEC circuit is to create genuine multipartite entanglement (GME) across all subsystems of physical qubits. We introduce a conditional witnessing technique to certify GME that i... https://herbsdailyes.shop/product-category/catheters-and-sheaths-intermittent/
