Quantum information processing and creation of nonclassical and
nonlocal quantum states require presence of a nonlinear element,
being challenging to construct and representing a physical resource
that should be used in an optimal way. We propose a protocol
exploiting only weak cross-Kerr nonlinearities for generating a wide
class of continuous variables states of optical systems separated by
distances up to more than 100 km. The equation, derived in our work,
shows that the protocol parameters are defined in a unique way by
the desired final state.
Key words:
quantum information, weak cross-Kerr nonlinearity,
qubit-like entangled state, peculiarity of projecting
