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

Macroscopic quantum states: Measures, fragility, and implementations (2017, methodology): “A similar reasoning as before leads to measure the frequency components of the so-called Stratonovich-Weyl distribution, which is the spin-equivalent of the Wigner function (Agarwal, 1998; Klimov and Chumakov, 2009).”
Performance and structure of single-mode bosonic codes (2017, methodology): “This channel can be expressed via unraveling [18, 30–32] or Lie-algebraic [33] techniques in the Kraus representation, To leading order in γ , expansions of the ﬁrst two Kraus operators suﬃce, γ ˆ n and E 1 = √ γ ˆ a .”
Microwave photonics with superconducting quantum circuits (2017, background): “4, the qubit frequency also gets a Bloch–Siegert shift [321] g(2)/(ωq + ωr) due to the counter-rotating terms [436].”
