We present a way for fast implementation of a two-qubit controlled phase gate with superconducting flux qubits coupled to a cavity. A distinct feature of this proposal is that since only qubit-cavity resonant interaction and qubit-pulse resonant interaction are used, the gate can be performed much faster when compared with the previous proposals. This proposal does not require adjustment of the qubit level spacings during the gate operation. In addition, neither uniformity in the qubit…

Quantum logic gates operation using SQUID qubits in bimodal cavity
We present a scheme to realize the basic two-qubit logic gates such as the quantum phase gate and SWAP gate using a detuned microwave cavity interacting with three-level
Implementing the Quantum von Neumann Architecture with Superconducting Circuits
A quantum central processing unit that exchanges data with a quantum random-access memory integrated on a chip, with instructions stored on a classical computer is demonstrated.
Tunable quantum beam splitters for coherent manipulation of a solid-state tripartite qubit system
The result shows that the Landau–Zener–Stückelberg interference has great potential in precise control of the quantum states in the tripartite system and avoided crossings in the system's energy-level spectrum due to the qubit–TLS interaction act as tunable quantum beam splitters of wave functions.
Process Tomography of Quantum Memory in a Josephson Phase Qubit
Defects in Josephson junctions are considered a nuisance when it comes to using superconducting circuits as building blocks for a quantum-information processor. But if the interaction between the
