Adaptive Stabilizer State Fidelity Certification
An adaptive sequence of stabilizer gauges returns a certified fidelity interval, tightens it monotonically, and can outperform full stabilizer coverage for structured noise.
GHZ-W Genuinely Entangled Subspace Verification with Adaptive Local Measurements
Adaptive local protocols efficiently verify the three-qubit subspace spanned by GHZ and W states and expose fundamental limits on which low-dimensional entangled subspaces can be …
