New Theoretical Framework for Analysing Decoherence in Non-linear Resonators Used to Create Bosonic Qubits
(a,b) The Wigner distribution vs the photonic quadratures x = √ 2Re(α) and p = √ 2Im(α).
(a,b) The Wigner distribution vs the photonic quadratures x = √2Re(α) and p =√2Im(α). It is obtained from (a) the exact solution (7)-(4) and (b) the effective potential approximation (12). The red dots highlights location of the semi-classical fixed point (21) . The white lines shows the brunch-cuts of the effective potential (12). The system’s parameters are set to G = 10,Δ = 7, η = 1.

FTPI Professor Alex Kamenev's recent paper on qubit decoherence has been highlighted in an article by ROHAILT on QuantumZeitgeist.com.
