Black holes as bosonic Gaussian channels

  title={Black holes as bosonic Gaussian channels},

We identify the quantum channels corresponding to the interaction of a Gaussian quantum state with an already formed Schwarzschild black hole. Using recent advances in the classification of one-mode bosonic Gaussian channels we find that (with one exception) the black hole Gaussian channels lie in the non-entanglement breaking subset of the lossy channels C(loss), amplifying channels C(amp) and classical-noise channels B2. We show that the channel parameters depend on the black hole mass and…

We investigate the transmission of both classical and quantum information between two arbitrary observers in globally hyperbolic spacetimes using a quantum field as a communication channel. The field
Classical capacity of phase-sensitive Gaussian quantum channels
The analytical study of the solution of the optimization problem giving the Gaussian capacity of the single-mode fiducial Gaussian quantum channel shows that the dependence of theGaussian capacity on the environment noise squeezing is not monotonic.

We explore the multiparticle transition probabilities in Gaussian unitaries effected by a twomode Bogoliubov bosonic transformation on the mode annihilation and creation operators. We show that the
Capacities of Quantum Amplifier Channels
The capacities of quantum-limited amplifier channels are established for one of the most general communication tasks, characterized by the trade-off between classical communication, quantum communication, and entanglement generation or consumption and it is found that the capacities significantly outperform communication rates achieved with a naive time-sharing strategy.

This thesis studies the ultimate rate of reliably transmitting information, stored in quantum systems, through a noisy evolution, and considers communication over optical links, upon which future inter-city quantum communication networks will be built.
Upper bounds on secret-key agreement over lossy thermal bosonic channels
A recent advance in the theory of the teleportation simulation of single-mode phase-insensitive Gaussian channels is extended such that it now applies to the relative entropy of entanglement measure, and tighter upper bounds are found on the non-asymptotic secret-key-agreement capacity of the lossy thermal bosonic channel than were previously known.
Entanglement concentration for two-mode Gaussian states in non-inertial frames
Entanglement creation and concentration by means of a beam splitter (BS) is analysed for a generic two-mode bipartite Gaussian state in a relativistic framework. The total correlations, the purity

Quantum capacities of bosonic channels.
The quantum capacity for a class of Gaussian channels, including channels describing optical fibers with photon losses, is calculated by proving that Gaussian encodings are optimal by proved that Gaussians are optimal.
Optimal unitary dilation for bosonic Gaussian channels
The minimal number of quantum Gaussian environmental modes required to provide a unitary dilation of a multimode bosonic Gaussian channel is analyzed for both pure and mixed environments and a new quantity reflecting ''noisiness'' of bosonicGaussian channels is introduced.

The fate of classical information incident on a quantum black hole has been the subject of an ongoing controversy in theoretical physics, because a calculation within the framework of semi-classical
One-mode bosonic Gaussian channels: a full weak-degradability classification
It is shown that apart from the class of channels which are unitarily equivalent to the channels with additive classical noise, these maps can be characterized in terms of weak- and/or anti-degradability.
Black holes are almost optimal quantum cloners
If black holes were able to clone quantum states, a number of paradoxes in black hole physics would disappear. However, the linearity of quantum mechanics forbids exact cloning of quantum states.
Gaussian quantum information
This review focuses on continuous-variable quantum information processes that rely on any combination of Gaussian states, Gaussian operations, and Gaussian measurements, including quantum communication, quantum cryptography, quantum computation, quantum teleportation, and quantum state and channel discrimination.
Evaluating capacities of bosonic Gaussian channels

We show that, in order to preserve the equivalence principle until late times in unitarily evaporating black holes, the thermodynamic entropy of a black hole must be primarily entropy of entanglement
