Resource-Efficient Measurement-Device-Independent Entanglement Witness

Resource-Efficient Measurement-Device-Independent Entanglement Witness

Imperfections in experimental measurement schemes can lead to falsely identifying, or over estimating, entanglement in a quantum system. A recent solution to this is to define schemes that are robust to measurement imperfections-measurement-device-independent entanglement witness (MDI-EW). This approach can be adapted to witness all entangled qubit states for a wide …
