Robust Device-Independent Certification of Boolean-Phase Gates
Yunguang Han, Xingyuan Bu, Aleksandra Gočanin +1
Device-independent certification of a quantum gate requires the input and output tests to identify the same reference qubits. Self-testing the output Choi state alone does not guar…

Device-Independent Self-Testing of the Three-Qubit CCZ Hypergraph State
Yunguang Han, Xin Kuang, Xingyuan Bu +1
The three-qubit CCZ state is the smallest rank-three hypergraph state and an elementary entangled magic resource. Its cubic phase is governed by generalized stabilizers that are no…
