Stimulated Raman adiabatic passage in physics, chemistry, and beyond (2016, background): “Superconducting qubits are classified into three types, based on their degrees of freedom: charge (Bouchiat et al., 1998; Nakamura et al., 1999), flux (Friedman et al., 2000; van der Wal et al., 2000), and phase (Martinis et al., 2002), see Fig.”
Quantum information processing with superconducting circuits: a review (2016, methodology): “The threeJJ flux qubit [13, 14, 125] consists of an rfSQUID where the inductor L has been replaced by two JJs to provide large inductance with a small SQUID ring.”
Macroscopic quantum states: Measures, fragility, and implementations (2017, methodology): “Note that other experiments, for example, Hime et al. (2006); van der Wal et al. (2000) differ in the details, but also work with a double-well potential and prove the coherence via an avoided crossing.”
Mechanical systems in the quantum regime (2011, background): “t for larger and larger systems mainly due to decoherence [10, 11]. Superpositions have for example been created using the circulating current in superconducting quantum interference devices (SQUIDs) [12] and with fullerenes [13, 14]. Nanomechanical devices [15, 16] are interesting candidates to fur”
Circuit quantum electrodynamics (2010, background): “There are various schemes for incorporating a junction, leading to what are known as phase qubits [14], flux qubits [15, 16] and charge qubits [17, 18].”
