Quantum dynamics of superconducting nano-circuits: phase qubit, charge qubit and rhombi chains |
Abstract | ||
---|---|---|
We have studied different quantum dynamics of superconducting nano-circuits with Josephson junctions. A dc SQUID, when it is strongly decoupled from the environment, demonstrates two-level and multilevel dynamics. We have realized a two qubits coupled circuit based on a dc SQUID in parallel with an asymmetric Cooper pair transistor (ACPT). The ACPT behaves as a charge qubit. Its asymmetry produces a strong tunable coupling with the dc SQUID which is used to realize entangled states between the two qubits and new read-out of the charge qubit based on adiabatic quantum transfer. We have measured the current---phase relations of different rhombi chains in the presence or absence of quantum fluctuations which confirm theoretical predictions. |
