The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Atomic physics and quantum optics using superconducting circuits (2011, methodology): “Also, quantum process tomography was experimentally implemented on single [65] and two [66] phase qubits.”
Quantum process tomography of a universal entangling gate implemented with Josephson phase qubits (2009, unknown): “This is the first solid-state demonstration of QPT in a two-qubit system, as QPT has previously been demonstrated only with single solid-state qubit”
1 / f noise: Implications for solid-state quantum information (2013, background): “In (Neeley et al., 2008) the first quantum memory operation on a TLS in a phase qubit has been demonstrated.”
Ion-trap measurements of electric-field noise near surfaces (2014, background): “…been performed with superconducting qubits, where TLFs in the insulating layer of a Josephson junction have been spectroscopically resolved (Martinis et al., 2005) and the coherent manipulation of individual two-level defects has been demonstrated (Neeley et al., 2008; Lisenfeld et al., 2010).”
Hybrid quantum circuits: Superconducting circuits interacting with other quantum systems (2012, background): “Generally, TLSs are regarded as a nuisance because they cause decoherence (Ku and Yu, 2005; Martin et al., 2005).”
