EFFICIENT AND ROBUST CERTIFICATION OF GENUINE MULTIPARTITE ENTANGLEMENT IN NOISY QUANTUM ERROR CORRECTION CIRCUITS

Efficient and Robust Certification of Genuine Multipartite Entanglement in Noisy Quantum Error Correction Circuits

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 witness
