GHZ-W Genuinely Entangled Subspace Verification with Adaptive Local Measurements
Congcong Zheng, Ping Xu, Kun Wang +1
Genuinely entangled subspaces (GESs) are valuable resources in quantum information science. Among these, the three-qubit GHZ-W GES, spanned by the three-qubit Greenberger-Horne-Zei…

Efficient Verification of Stabilizer Code Subspaces with Local Measurements
Congcong Zheng, Xutao Yu, Zaichen Zhang +2
We address the task of verifying whether a quantum computer, designed to be protected by a specific stabilizer code, correctly encodes the corresponding logical qubits. To achieve…
