The possibility of achieving quantum communication using photons across interstellar distances is examined. For this, different factors are considered that could induce decoherence of photons, including the gravitational field of astrophysical bodies, the particle content in the interstellar medium, and the more local environment of the Solar System. The X-ray region of the spectrum is identified as the prime candidate to establish a quantum communication channel, although the optical and… 



Quantum coherence to interstellar distances

Quantum coherence could be sustained up to interstellar distances. It is shown that the photon mean free path in certain regions of the electromagnetic spectrum, such as within the radio or x-ray

Searching for Interstellar Quantum Communications

The modern search for extraterrestrial intelligence began with the seminal publications of Cocconi & Morrison and Schwartz & Townes, who proposed searching for narrowband signals in the radio

Quantum communications and quantum metrology in the spacetime of a rotating planet

This work studies how quantum systems that propagate in the spacetime of a rotating planet are affected by the curved background, and provides a comparison with the state of the art in parameter estimation obtained through classical means.

Long-distance teleportation of qubits at telecommunication wavelengths

Here is a long-distance experimental demonstration of probabilistic quantum teleportation, where qubits are carried by photons and teleported onto photons of 1.3 µm wavelength from one laboratory to another, separated by 55 m but connected by 2 km of standard telecommunications fibre.

Spacetime effects on satellite-based quantum communications

We investigate the consequences of space-time being curved on space-based quantum communication protocols. We analyze tasks that require either the exchange of single photons in a certain

Communications: Quantum teleportation across the Danube

This work describes the high-fidelity teleportation of photons over a distance of 600 metres across the River Danube in Vienna, with the optimal efficiency that can be achieved using linear optics.

Research Progress Of Quantum Repeaters

The quantum repeater can divide the long- distance communication distance into several segments, and then perform quantum key distribution in several segments respectively, to achieve long-distance information transmission.

Quantum teleportation of multiple degrees of freedom of a single photon

This work uses photon pairs entangled in both degrees of freedom (that is, hyper-entangled) as the quantum channel for teleportation, and develops a method to project and discriminate hyper-ENTangled Bell states by exploiting probabilistic quantum non-demolition measurement, which can be extended to more degrees offreedom.

A comprehensive design and performance analysis of low Earth orbit satellite quantum communication

Optical quantum communication utilizing satellite platforms has the potential to extend the reach of quantum key distribution (QKD) from terrestrial limits of ∼200 km to global scales. We have

Experimental quasi-single-photon transmission from satellite to earth.

A direct experimental demonstration of the satellite-ground transmission of a quasi-single-photon source and a SNR of better than 16:1 is obtained, which is sufficient for a secure quantum key distribution.
