Quantum Communications Sent Through Regular Telecom Networks for the First Time
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists successfully transmitted quantum communications across 150 miles of existing commercial telecom infrastructure in Germany, proving that secure quantum networks can be implemented without rebuilding current systems.
📈 One key stat: The quantum key distribution system achieved 110 bits per second in a star-shaped network over 150 miles, doubling the previous distance record for practical quantum communications without cryogenic cooling.
💬 One key quote: “This demonstration indicates that advanced quantum communications protocols that exploit the coherence of light can be made to work over existing telecom infrastructure—a massive savings in time and money that would also enable small-scale experimentation in quantum computing to flourish.”
1️⃣ The big picture: German scientists have achieved a major breakthrough in quantum communications by successfully transmitting quantum data across 150 miles using existing commercial fiber optic lines. This demonstration, published in Nature, marks the first time quantum communications have been sent through multiple telecom data centers in a real-world setting. The researchers used a coherence-based twin-field quantum key distribution system that doesn’t require specialized equipment like cryogenic cooling. This practical approach could dramatically accelerate the implementation of quantum networks without requiring completely new infrastructure, making quantum communications more accessible and cost-effective.
2️⃣ Why is this good news: This advancement significantly reduces the barriers to implementing quantum communications by proving we can use existing telecom infrastructure rather than building entirely new systems. The technology achieved a repeater-like efficiency that doubled the distance for practical quantum key distribution without specialized cooling equipment. The approach creates immense cost savings for governments and companies looking to establish quantum networks. For the broader public, this means more secure communications could arrive sooner and be more widely available, while researchers can now conduct small-scale quantum experiments more affordably.
3️⃣ What’s next: Companies like IBM, which recently announced $150 billion in quantum computing investments, can now potentially integrate with existing telecom infrastructure. More practical applications of quantum key distribution can be tested in various real-world settings at lower costs. Researchers will likely focus on further improving data transmission speeds beyond the current 110 bits per second while maintaining or extending the communication distance.
