Quantum information transmitted without loss: so you can study black holes in detail

If we use a new approach in the quantum error correction code, then we get observations on the earlier

inaccessible wavelengths. This method could allow us to better study black holes, exoplanets, the solar system, and the surfaces of distant stars.

The method of interferometry is that it is necessarycombine light from different telescopes to create images of the object. Very long baseline radio interferometry (VLBI) is an approach used by astronomers in which signals from an astronomical radio source (black holes, quasars, pulsars, etc.) are combined to produce detailed images of their structure and activity.

But with this approach, there is a loss of information, noise. And the resulting light, as a rule, has a quantum nature. These are all limitations that interfere with observations.

The idea of ​​the authors of the new work is to move from microwaves to optical frequencies. These methods are equally applicable to infrared radiation.

The key to overcoming these limitations isuse of quantum communication methods. All coherent light waves must be used to transfer optical information between two quantum states. As a result, according to the authors, it will be possible to transmit information without loss and noise.
