Searching for highly entangled multi-qubit states
We present a simple numerical optimisation procedure to search for highly entangled states of 2, 3, 4 and 5 qubits. We develop a computationally tractable entanglement measure based on the negative partial transpose (NPT) criterion, which can be applied to quantum systems of an arbitrary number of qubits. The search algorithm attempts to optimise this entanglement cost function to find the maxi...
متن کاملFully multi-qubit entangled states
We investigate the properties of different levels of entanglement in graph states which correspond to connected graphs. Combining the operational definition of graph states and the postulates of entanglement measures, we prove that in connected graph states of N > 3 qubits there is no genuine three-qubit entanglement. For certain classes of graph states, all genuine k-qubit entanglement, 2 ≤ k ...
متن کاملDecoherence of multi-dimensional entangled coherent states
For entangled states of light both the amount of entanglement and the sensitivity to noise generally increase with the number of photons in the state. The entanglement-sensitivity tradeoff is investigated for a particular set of states, multi-dimensional entangled coherent states. Those states possess an arbitrarily large amount of entanglement E provided the number of photons is at least of or...
متن کاملA Structured Dictionary Learning Method for Multi-scale Sparse Representation
In this paper, we address the problem of learning multi-scale sparse representations of natural images using structured dictionaries. Dictionaries learned by traditional algorithms have two major limitations: lack of structure and fixed size. These methods treat atoms independently from each other, and do not exploit possible relationships between them. Fixed size of atoms restricts the flexibi...
متن کاملUncertainty Relations for Entangled States
A generalized uncertainty relation for an entangled pair of particles is obtained if we impose a symmetrization rule for all operators that we should use when doing any calculation using the entangled wave function of the pair. This new relation reduces to Heisenberg’s uncertainty relation when the particles have no correlation and suggests that we can have new lower bounds for the product of p...
