Coherent operation of coupled superconducting flux qubits
We study the quantum operation of coupled superconducting flux qubits under a microwave irradiation. The flux qubits can be described as magnetic dipole moments in the limit of weak microwave field amplitude consistent with usual experimental situations. With the Hamiltonian for coupled qubits under a microwave field, we show that a strong coupling enables to realize the high performance contro...
متن کاملFlux-based superconducting qubits for quantum computation
Superconducting quantum circuits have been proposed as qubits for developing quantum computation. The goal is to use superconducting quantum circuits to model the measurement process, understand the sources of decoherence, and to develop scalable algorithms. A particularly promising feature of using superconducting technology is the potential of developing high-speed, on-chip control circuitry ...

متن کاملQuantum acoustics with superconducting qubits.
Mechanical objects have important practical applications in the fields of quantum information and metrology as quantum memories or transducers for measuring and connecting different types of quantum systems. The field of electromechanics is in pursuit of a robust and highly coherent device that couples motion to nonlinear quantum objects such as superconducting qubits. Here, we experimentally d...
متن کاملSupplementary information for Fast Accurate State Measurement with Superconducting Qubits
where CF and VF are the filter capacitance and voltage amplitude. See Fig. 1(a). To compute the ratio Vq/VF we use voltage division. We make the crucial observation that to calculate the qubit damping we must analyze the circuit impedances at the qubit frequency. Because the qubit is off resonance from the measurement resonator, the measurement resonator’s impedance Zr is lower than the impedan...
