Engineering mixed states in a degenerate four-state system
Attila Karpati, Zsolt Kis, Peter Adam
A method is proposed for preparing any pure and a wide class of mixed quantum states in the decoherence-free ground-state subspace of a degenerate multilevel lambda system. The sch…

Arbitrary rotation and entanglement of flux SQUID qubits
Z. Kis, E. Paspalakis
We propose a new approach for the arbitrary rotation of a three-level SQUID qubit and describe a new strategy for the creation of coherence transfer and entangled states between tw…
