Simulating topological contextuality

Topological quantum computation is based on braiding of non-abelian anyons; however, people know such operation is not "universal" to establish a full-stack quantum advantage. Here we introduce quantum contextuality to the topological system and show through magic state distillation it can activate universality together with braiding. Furthermore, contextuality inherits the traits of fault-tolerant in the topological system. We justify the computation architecture with our dissipative photonic quantum processor.

Nonlocality without inequality

Describing the quantum world using classical language can lead to a seemingly contradictory result "+1=-1". Here we give a recipe for constructing such paradoxes in graph states, and show these paradoxes exist even in mixed states. Our result can be used in multipartite entanglement witness and quantum state verification.
