Generating optimal states for a homodyne Bell test
Sonja Daffer, Peter L. Knight
We present a protocol that produces a conditionally prepared state that can be used for a Bell test based on homodyne detection. Based on the results of Munro [PRA 1999], the state…
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…
