Steering Bell-diagonal states.
We investigate the steerability of two-qubit Bell-diagonal states under projective measurements by the steering party. In the simplest nontrivial scenario of two projective measurements, we solve this problem completely by virtue of the connection between the steering problem and the joint-measurement problem. A necessary and sufficient criterion is derived together with a simple geometrical in...
متن کاملBell-states diagonal relativistic multispinor entanglement witnesses in arbitrary dimensions
Two kinds of Bell-states diagonal relativistic multispinor entanglement witnesses (EW) are constructed by using the Euclidean representation of the algebra of Dirac γ matrices in the space-time of arbitrary dimension d, where the first kind can detect some Bell-states diagonal m-partite multispinor bound entangled states in Hilbert space of dimension 2m⌊d/2⌋, including the bipartite relativisti...
متن کاملA Class of Bell Diagonal States and Entanglement Witnesses
We analyze special class of bipartite states – so called Bell diagonal states. In particular we provide new examples of bound entangled Bell diagonal states and construct the class of entanglement witnesses diagonal in the magic basis.
متن کاملUsing separable Bell-diagonal states to distribute entanglement.
One of the many bizarre features of entanglement is that Alice, by sending a qubit to Bob in a separable state, can generate some entanglement between herself and Bob. This protocol is stripped down to the bare essentials to better elucidate the key properties of the initial resource state that enable this entanglement distribution. The necessary and sufficient conditions under which the correl...
متن کاملQuantum steering, entanglement and Bell nonlocality
Quantum steering, the ability of one party to perform a measurement on their side of an entangled system with different outcomes leading to different sets of states for another part of the entangled system arbitrarily far away, is a purely quantum phenomena with no classical analogue. However, it is closely related (and indeed equivalent for pure states) to entanglement and Bell nonlocality. Th...
