Feedback control of quantum entanglement in a two-spin system
— A pair of spins is the most simple quantum system that can possess entanglement, a non-classical property playing an essential role in quantum information technologies. In this...

Unique Games with Entangled Provers are Easy
We consider one-round games between a classical verifier and two provers who share entanglement. We show that when the constraints enforced by the verifier are ‘unique’ cons...

Reasoning about Entanglement and Separability in Quantum Higher-Order Functions
We present a logical approach to the separability analysis issue for a functional quantum computation language. This logic is inspired by previous works on logical analysis of alia...

Characterizing Pure High-Order Entanglements in Lexical Semantic Spaces via Information Geometry
An emerging topic in Quantuam Interaction is the use of lexical semantic spaces, as Hilbert spaces, to capture the meaning of words. There has been some initial evidence that the p...

Simulation of n-qubit quantum systems. II. Separability and entanglement
Studies on the entanglement of n-qubit quantum systems have attracted a lot of interest during recent years. Despite the central role of entanglement in quantum information theory...
