All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

We review the theory of entanglement measures, concentrating mostly on the finite
dimensional two-party case. Topics covered include: single-copy and asymptotic …

We give a review on entanglement purification for bipartite and multipartite quantum states,
with the main focus on the theoretical work carried out by our group in the last couple of …

Quantum entanglement serves as a valuable resource for many important quantum
operations. A pair of entangled qubits can be shared between two agents by first preparing a …

We investigate entanglement purification protocols based on hashing, where a large
number of noisy entangled pairs are jointly processed to obtain a reduced number of perfect …

Quantum information theory is a multidisciplinary field whose objective is to understand what
happens when information is stored in the state of a quantum system. Quantum mechanics …

Quantum mechanics allows an information carrier to traverse through multiple trajectories of
communication channels simultaneously, this leads us to quantum trajectories where …

Quantum entanglement shared by remote network nodes serves as a valuable resource for
promising applications in distributed computing, cryptography, and sensing. However …

We present a secure quantum dialogue protocol using non-maximally entangled two-
particle states via entanglement swapping at first, and then discuss the requirements for a …

PhD thesis (University of York). The thesis covers in a unified way the material presented in
