Quasi inversion of qubit channels
Vahid Karimipour, Fabio Benatti, Roberto Floreanini
Quantum operations, or quantum channels cannot be inverted in general. An arbitrary state passing through a quantum channel looses its fidelity with the input. Given a quantum chan…
Entangled States as Robust and Re-usable Carriers of Information
Shima Emamipanah, Marzieh Asoudeh, Vahid Karimipour
Entangled states can be used as secure carriers of information much in the same way as carriers are used in classical communications. In such protocols, quantum states are uploaded…
A simple model of Small-World Quantum Networks
Ashkan Abedi, Vahid Karimipour
A simple model of small world quantum networks, in which a central node plays essential role, is introduced for sharing entanglement over long distances. In view of the challenges…
Quantum Key Distribution with no Shared Reference Frame
Fatemeh Rezazadeh, Azam Mani, Vahid Karimipour
Any quantum communication task requires a common reference frame (i.e. phase, coordinate system). In particular, Quantum Key Distribution requires different bases for preparation a…
Exact generation of quantum states by the dynamics of spin chains
Morteza Moradi, Vahid Karimipour
We design a quasi-one dimensional spin chain with engineered coupling strengths such that the natural dynamics of the spin chain evolves a single excitation localized at the left h…
Entanglement-assisted communication in the absence of shared reference frame
Ali Beheshti, Sadegh Raeisi, Vahid Karimipour
Alice wants to convey the value of a parameter to Bob with whom she does not share a reference frame. What physical object can she use for this task? Shall she encode this value in…
