Robust self-testing of (almost) all pure two-qubit states
In a nonlocal scenario, physically isolated players each have a device that inputs and outputs classical information. Certain correlations between the joint input and output of the devices almost uniquely identify the quantum state that they share. This phenomenon is known as self-testing and has applications in quantum cryptography with untrusted devices. It was for example shown that for ever...
متن کاملLocal symmetry properties of pure 3 - qubit states
Entanglement types of pure states of three spin-12 particles are classified by means of their stabilisers in the group of local unitary transformations. It is shown that the stabiliser is generically discrete, and that a larger stabiliser indicates a stationary value for some local invariant. We describe all the exceptional states with enlarged stabilisers.
متن کاملN - qubit pure states
We present a multipartite entanglement measure for N -qubit pure states, using the norm of the correlation tensor which occurs in the Bloch representation of the state. We compute this measure for several important classes of N -qubit pure states such as GHZ states, W states and their superpositions. We compute this measure for interesting applications like one dimensional Heisenberg antiferrom...
متن کاملOn local invariants of pure three-qubit states
We study invariants of three-qubit states under local unitary transformations, i.e. functions on the space of entanglement types, which is known to have dimension 6. We show that there is no set of six algebraically independent polynomial invariants of degree ≤ 6, and find such a set with maximum degree 8. We describe an intrinsic definition of a canonical state on each orbit, and discuss the (...
