“…Moreover, the conclusions drawn from this study will be fundamental in alternative areas of quantum communications outside of the quantum Internet, such as space quantum communications or free space optical communications. [34][35][36][37][38][39][40][41] The outline of the paper is as follows: In Section 2, the bridge between entanglement and QFT is introduced; Section 3 describes the main three applications of entanglement present in the quantum Internet expressed via QFT, while in Section 4 all applications described in the previous sections are implemented on a 5-qubit IBM Q platform. [31] Finally, the conclusions are presented in Section 5.…”

In this study, the bridge between quantum fourier transform (QFT) and the most important effect inside quantum physics-entanglement-is presented. Moreover, all the applications of entanglement are impregnated by this equivalence, which concludes in the first spectral approach to the quantum Internet of the literature, which will allow the development of configurations that are more immune to noise as well as fault-tolerant. Several protocols used in the quantum Internet are implemented on a 5-qubit international business machine quantum (IBM Q) platform, experimentally verifying the aforementioned equivalence.

This article presents the QuantSaT-PT project, an effort to create the first Portuguese nanosatellite for space to ground quantum communication. Focused on the Attitude Determination and Control System, it describes the different elements that allow for the attainment of diverse accuracy levels required for separate mission stages. Given the harsh pointing precision necessary for establishing a quantum downlink, the implementation of this module presents a major challenge in the Cubesat field. Furthermore, the introduced architecture aims to reduce system cost by replacing the state-of-the-art star tracker with ground beacon detection.

The use of CubeSats promises several advantages within a low economical budget margin for different missions. Nowadays, data transfer through optical channels (lasercom) is considered a potential technology for satellite wireless communications, providing several advantages in terms of data transfer rate with lower energy consumption. However, a main drawback is the location of the Optical Ground Station (OGS). Therefore, an artificial vision algorithm for the processing of images captured by the camera of a CubeSat is proposed in this work, in order to carry out the identification and recognition of an OGS by means of a beacon signal, to aid the Pointing, Acquisition and Tracking (PAT) onboard subsystem for the communication’s stage.
