Minimum decoherence cat-like states in Gaussian noisy channels
We address the evolution of cat-like states in general Gaussian noisy channels, by considering superpositions of coherent and squeezed coherent states coupled to an arbitrarily squeezed bath. The phase space dynamics is solved and decoherence is studied, keeping track of the purity of the evolving state. The influence of the choice of the state and channel parameters on purity is discussed and ...
متن کاملOptimized teleportation in Gaussian noisy channels
We address continuous variable quantum teleportation in Gaussian quantum noisy channels, either thermal or squeezed-thermal. We first study the propagation of twin-beam and evaluate a threshold for its separability. We find that the threshold for purely thermal channels is always larger than for squeezed-thermal ones. On the other hand, we show that squeezing the channel improves teleportation ...
متن کاملThe Forced Harmonic Oscillator, Decoherence, and Schrödinger Cat States
The harmonic oscillator is a very significant problem in quantum mechanics, because it is one of the very few, relatively non-trivial problems that has an exact analytic solution. In addition to this, the harmonic oscillator solution and algebraic formalism has applications throughout modern physics (e.g. many particle systems, QED, quantum field theory, approximations of real systems such as m...
متن کاملOptimal Communication of States of Dynamical Systems over Gaussian Channels with Noisy Feedback: The Scalar Case
We consider the problem of communicating the state of a dynamical system via a Shannon Gaussian channel. The receiver, which acts as both a decoder and estimator, observes the noisy measurement of the channel output and makes an optimal estimate of the state of the dynamical system in the minimum mean square sense. Noisy feedback from the receiver to the transmitter is present. The transmitter ...
متن کاملOn the Reliability of Gaussian Channels with Noisy Feedback
We derive bounds on the reliability of the additive white Gaussian noise channel Y = X +Z with output fed back to the transmitter over independent additive white Gaussian noise channel Ỹ = Y + Z̃ . These bounds appear to be new even for transmission at zero rate. As a corollary, it is shown that linear feedback coding schemes of finite-dimensional constellation, such as the celebrated Schalkwijk...
