Witnessing the Effective Entanglement in the COW Protocol
F. Rezazadeh, A. Mani, M. Khodabandeh +2
We present a rigorous mathematical framework for verifying effective entanglement in a Coherent One-Way (COW) quantum key distribution setup. In particular, we introduce a two-para…

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…

The power of a shared singlet state, compared with a shared reference frame
F. Rezazadeh, A. Mani, V. Karimipour
We show that a Shared Singlet State (SSS) can supersede a Shared Reference Frame (SRF) in certain quantum communication tasks, i.e. tasks in which two remote players are required t…
