Resonantly phase-matched Josephson junction traveling wave parametric amplifier
Kevin O'Brien, Chris Macklin, Irfan Siddiqi +1
We develop a technique to overcome phase-mismatch in Josephson-junction traveling wave parametric amplifiers in order to achieve high gain over a broad bandwidth. Using "resonant p…
Observation of measurement-induced entanglement and quantum trajectories of remote superconducting qubits
Nicolas Roch, Mollie E. Schwartz, Felix Motzoi +7
The creation of a quantum network requires the distribution of coherent information across macroscopic distances. We demonstrate the entanglement of two superconducting qubits, sep…
Observing single quantum trajectories of a superconducting qubit
K. W. Murch, S. J. Weber, C. Macklin +1
The length of time that a quantum system can exist in a superposition state is determined by how strongly it interacts with its environment. This interaction entangles the quantum…
Quantum feedback control of a superconducting qubit: Persistent Rabi oscillations
R. Vijay, C. Macklin, D. H. Slichter +5
The act of measurement bridges the quantum and classical worlds by projecting a superposition of possible states into a single, albeit probabilistic, outcome. The time-scale of thi…
Heralded state preparation in a superconducting qubit
J. E. Johnson, C. Macklin, D. H. Slichter +4
We demonstrate high-fidelity, quantum nondemolition, single-shot readout of a superconducting flux qubit in which the pointer state distributions can be resolved to below one part…
Dispersive readout of a flux qubit at the single photon level
J. E. Johnson, E. M. Hoskinson, C. Macklin +3
A superconducting flux qubit is inductively coupled to a Superconducting QUantum Interference Device (SQUID) magnetometer, capacitively shunted to form a 1.294-GHz resonator. The q…
