Bloch Equations and Completely Positive Maps
Sonja Daffer, Krzysztof Wodkiewicz, John K. McIver
The phenomenological dissipation of the Bloch equations is reexamined in the context of completely positive maps. Such maps occur if the dissipation arises from a reduction of a un…
Completely positive maps with memory
Sonja Daffer, Krzysztof Wodkiewicz, James D. Cresser +1
The prevailing description for dissipative quantum dynamics is given by the Lindblad form of a Markovian master equation, used under the assumption that memory effects are negligib…
Nonlocality of Two-Mode Squeezing with Internal Noise
Sonja Daffer, Krzysztof Wodkiewicz, John K. McIver
We examine the quantum states produced through parametric amplification with internal quantum noise. The internal diffusion arises by coupling both modes of light to a reservoir fo…
Quantum Markov Channels for Qubits
Sonja Daffer, Krzysztof Wodkiewicz, John K. McIver
We examine stochastic maps in the context of quantum optics. Making use of the master equation, the damping basis, and the Bloch picture we calculate a non-unital, completely posit…
