Fast, tunable, high fidelity cZ-gates between superconducting qubits with parametric microwave control of ZZ-coupling
X. Y. Jin, K. Cicak, Z. Parrott +6
Future quantum information processors require tunable coupling architectures that can produce high fidelity logical gates between two or more qubits. Parametric coupling is a power…
Goldstone Boson Scattering with a Light Composite Scalar
T. Appelquist, R. C. Brower, K. K. Cushman +14
The appearance of a light composite scalar resonance in nearly conformal gauge-fermion theories motivates further study of the low energy structure of these theories. To this…
Efficient qubit measurement with a nonreciprocal microwave amplifier
F. Lecocq, L. Ranzani, G. A. Peterson +5
The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is res…
Ultrastrong parametric coupling between a superconducting cavity and a mechanical resonator
G. A. Peterson, S. Kotler, F. Lecocq +5
We present a new optomechanical device where the motion of a micromechanical membrane couples to a microwave resonance of a three-dimensional superconducting cavity. With this arch…
