Nonadiabatic nuclear-electron dynamics: a quantum computing approach
Arseny Kovyrshin, Mårten Skogh, Lars Tornberg +6
The combined quantum electron-nuclear dynamics is often associated with the Born-Huang expansion of the molecular wave function and the appearance of nonadiabatic effects as a pert…
Probing the quantum vacuum with an artificial atom in front of a mirror
I. -C. Hoi, A. F. Kockum, L. Tornberg +4
Quantum fluctuations of the vacuum are both a surprising and fundamental phenomenon of nature. Understood as virtual photons flitting in and out of existence, they still have a ver…
Reversing quantum trajectories with analog feedback
G. de Lange, D. Ristè, M. J. Tiggelman +6
We demonstrate the active suppression of transmon qubit dephasing induced by dispersive measurement, using parametric amplification and analog feedback. By real-time processing of…
Quantum nondemolition detection of a propagating microwave photon
Sankar R. Sathyamoorthy, L. Tornberg, Anton F. Kockum +5
The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement.…
Steady state entanglement of two superconducting qubits engineered by dissipation
Florentin Reiter, L. Tornberg, Göran Johansson +1
We present a scheme for the dissipative preparation of an entangled steady state of two superconducting qubits in a circuit QED setup. Combining resonator photon loss, a dissipativ…
Giant Cross Kerr Effect for Propagating Microwaves Induced by an Artificial Atom
Io-Chun Hoi, C. M. Wilson, Göran Johansson +4
We have investigated the cross Kerr phase shift of propagating microwave fields strongly coupled to an artificial atom. The artificial atom is a superconducting transmon qubit in a…
