![[Recap] Top 5 blog articles of 2021](https://6285392.fs1.hubspotusercontent-na1.net/hub/6285392/hubfs/blog/Blog%20covers/ALIRO%20%5BRecap%5D%20Top%205%20blog%20articles%20of%202021.png?length=1200&name=ALIRO%20%5BRecap%5D%20Top%205%20blog%20articles%20of%202021.png)
2021 was an exciting year for quantum networks. In January 2021, we launched the Aliro blog to provide a go-to source for news, analysis, and educational content focused specifically on quantum networks. We could not have predicted all the progress that was made in the past year. To help our readers keep track of everything, we launched a newsletter, the Quantum Connect, which summarizes the key news in quantum networking each month. If you're interested in staying up to date with quantum networking news, you can sign up using the form in the footer of this page.
Now, here were the top 5 posts from the Aliro Blog in 2021:
1. Quantum entanglement communication
The first building block in understanding how quantum networks work: quantum entanglement. In this introductory post, learn the first basic concepts that will help you understand how quantum networks use entanglement to communicate. For a deeper introduction, read our post on how bell states are used in quantum networks.
2. What are quantum repeaters?
Quantum repeaters are the key technology for unlocking long-distance quantum communication. This post covered how quantum repeaters work, breaking down their function into three generations of improving technology.
3. 5 quantum networking companies to watch in 2021
The commercial quantum networking industry is rapidly emerging, as described by Accenture's recent report. We were not disappointed by any of the companies on this list. Look back to see what we were watching for in 2021 and keep an eye out for 2022 outlooks.
4. Quantum teleportation: transferring qubits on a quantum network
The fundamental service of quantum networks is distributing entanglement. The next step is quantum teleportation. Teleportation is the layer between entanglement and higher layer applications, like distributed quantum computing. Learn more about how teleportation actually works.
5. What is a quantum network?
What can quantum networks actually be used for? In this post, we highlight some of the fundamental building blocks of quantum networks and introduce three key application areas: secure communication, quantum sensing, and distributed quantum computing.
It was an exciting year for quantum networking technology. Keep an eye out for our 2022 outlook in the new year!
