Excitation of superconducting qubits from hot non-equilibrium quasiparticles
J. Wenner, Yi Yin, Erik Lucero +15
Superconducting qubits probe environmental defects such as non-equilibrium quasiparticles, an important source of decoherence. We show that "hot" non-equilibrium quasiparticles, wi…
Controlled catch and release of microwave photon states
Yi Yin, Yu Chen, Daniel Sank +13
The quantum behavior of superconducting qubits coupled to resonators is very similar to that of atoms in optical cavities [1, 2], in which the resonant cavity confines photons and…
Dynamic quantum Kerr effect in circuit quantum electrodynamics
Yi Yin, H. Wang, M. Mariantoni +14
A superconducting qubit coupled to a microwave resonator provides a controllable system that enables fundamental studies of light-matter interactions. In the dispersive regime, pho…
Surface spin fluctuations probed with flux noise and coherence in Josephson phase qubits
Daniel Sank, R. Barends, Radoslaw C. Bialczak +15
We measure the dependence of qubit phase coherence and surface spin induced flux noise on inductor loop geometry. While wider inductor traces change neither the flux noise power sp…
Deterministic entanglement of photons in two superconducting microwave resonators
H. Wang, Matteo Mariantoni, Radoslaw C. Bialczak +12
Quantum entanglement, one of the defining features of quantum mechanics, has been demonstrated in a variety of nonlinear spin-like systems. Quantum entanglement in linear systems h…
Decoherence Dynamics of Complex Photon States in a Superconducting Circuit
H. Wang, M. Hofheinz, M. Ansmann +9
Quantum states inevitably decay with time into a probabilistic mixture of classical states, due to their interaction with the environment and measurement instrumentation. We presen…
