Circuit quantum electrodynamics (2020, background): “…Kerr nonlinearity which overwhelms the cavity decay, K/κ > 1, has enabled a number of similar experiments such as the observation of collapse and revival of a coherent state in a Kerr medium (Kirchmair et al., 2013) and the preparation of cat states with nearly 30 photons (Vlastakis et al., 2013).”
Microwave photonics with superconducting quantum circuits (2017, background): “This dispersive coupling between a qubit and a resonator can be used to simultaneously manipulate hundreds of photons, to create superpositions of coherent states [367], and to control photon states [368].”
Dynamically protected cat-qubits: a new paradigm for universal quantum computation (2013, positive): “As supporting indications, similar devices with parameters close to those required in this paper have been recently realized and characterized experimentally [20, 22].”
Cavity magnonics (2021, background): “(122) can be used to encode arbitrary qubit states into a nonclassical state of magnons (Leghtas et al., 2013; Vlastakis et al., 2013).”
New class of quantum error-correcting codes for a bosonic mode (2016, methodology): “Remarkably, it is also now possible to make quantum nondemolition measurements of photon number parity [39], which can be used to greatly simplify the measurement of Wigner functions [32,38,39].”
Macroscopic quantum states: Measures, fragility, and implementations (2017, background): “Vlastakis et al. (2013); Wang et al. (2016a) reported on a set of multi-photon operations using a superconducting charge qubit called transmon, coupled to waveguide cavity resonators.”
Observing Topological Invariants Using Quantum Walks in Superconducting Circuits (2016, methodology): “To measure the Berry phase, we therefore apply direct Wigner tomography to the final cavity state [19,31,32].”
Hybrid discrete- and continuous-variable quantum information (2014, background): “Such states have been deterministically realized in the motional state of a trapped ion [39] and in the microwave regimes by entangling a standing CV microwave field to a flying Rydberg atom followed by a projective DV measurement of the atom [28, 40] and through a strong, dispersive interaction wit”
