Conditions for the existence of positive operator valued measures
Maximilian Schumacher, Gernot Alber
Sufficient and necessary conditions are presented for the existence of -positive operator valued measures (-POVMs) valid for arbitrary-dimensional quantum systems. A…

Typical bipartite steerability and generalized local quantum measurements
Maximilian Schumacher, Gernot Alber
Recently proposed correlation-matrix based sufficient conditions for bipartite steerability from Alice to Bob are applied to local informationally complete positive operator valued…

Bipartite entanglement detection by local generalized measurements
Maximilian Schumacher, Gernot Alber
Entanglement detection by local measurements, which can possibly be performed by far distant observers, are of particular interest for applications in quantum key distribution and…
