Quantum Delta NL(QDNL) says that the Internet must be superseded by quantum technology within 20 years.
In the next ten years, quantum computers are expected to get to the point where they may crack the cryptographic protocols that now protect private information, banks, and governments. Dutch researchers and industry leaders have begun developing a new kind of internet that is intended to withstand even the most advanced eavesdroppers in light of this threat.
In 2023, the Quantum Communication Infrastructure Nederland (QCINed) program was introduced as part of the national endeavor to develop this defense. QCINed’s objective is to include quantum key distribution (QKD) into the nation’s current fibre network, establishing a barrier that would make any attempt at eavesdropping instantly noticeable.
A Novel Defense for Electronic Communications
Currently used digital encryption relies on intricate mathematical problems that, if sufficiently large, can be solved by a classical computer. A previously secure key becomes public when quantum techniques, like Shor’s algorithm, factor such problems in polynomial time. According to the Dutch government, current precautions are basically “child’s play” in the context of a quantum machine in the future.
Quantum Key Distribution (QKD) is the suggested remedy; it is a method that creates a shared secret key using individual photons. According to the basic idea, any communication interception results in a noticeable inaccuracy in the data stream because quantum particles are perturbed when measured. The parties involved in communication delete the key and try again if the mistake rate exceeds a certain threshold. In real life, this guarantees that a possible spy will be detected before they can read the communication.

Construction of the Quantum Backbone
QCINed establishes its first operational testbed between Utrecht and Amsterdam. In order to achieve a scalable quantum-enabled network, it is essential to show that quantum and classical channels can coexist on the same physical infrastructure. This experiment shows how QKD can be integrated with the common optical fibre used for internet traffic.
The Hague is connected to Amsterdam by a second line in the show. The purpose of this corridor is to provide the ministries of justice and foreign affairs with complete confidence in exchanging secret material. This collaboration between academia and government creates a model for safe government communications throughout Europe by exposing the network to laws and actual traffic.
The Dutch project is part of the Digital Europe-funded European Quantum Communication Infrastructure (EuroQCI) program, which funds national projects to construct a continental quantum internet. QCINed received €10 million from the European Commission and the Dutch Ministry of Economic Affairs over 30 months.
It is coordinated nationally by Quantum Delta NL (QDNL). It brings together top technological companies, academic institutions, and government agencies to speed up the development of hardware, software, and quantum sensing.

From laboratories to the city
To promote the experimentation of quantum-secure protocols by startups, companies, and research institutions, an open test network has been established in Eindhoven. Being a centre of technology, Eindhoven allows developers to quickly iterate on hardware and software, expanding the possibilities of QKD. This testbed is critical for demonstrating novel error-correction and key-management techniques that will be necessary as the network grows beyond a small number of initial locations.
QCINed is interacting with partners in Brussels, Berlin, and the capitals of southern Europe in addition to the Netherlands. A continental quantum backbone connecting national networks is the ultimate goal, forming a network of safe channels that can transport private information across borders without risk of compromise. Regional testbeds are the first step in this incremental plan, which involves improving the technology before extending into a pan-European grid. The evolution of the classical internet, which began as a collection of specialised research networks before evolving into a worldwide public utility, is reflected in this staged method.

Gazing Straight Ahead
Governments, businesses that manage a lot of sensitive data, and institutions are the direct benefits of QCINed. The technology is anticipated to eventually reach regular consumers by reducing the entrance barrier for quantum-secure communications. Secure voting systems, tamper-proof supply chains, and real-time, privacy-preserving data analytics are just a few of the new businesses that the quantum internet will create as it develops.
The development of QCINed is a significant step towards a time when digital communication can resist the strength of quantum computers. The theoretical promise of quantum cryptography is being turned into a workable, deployable technology by Dutch researchers by incorporating QKD into already-existing fibre networks. Because of the program’s collaborative model, which brings together government, business, and academia, the final solutions are guaranteed to be both technically sound and economically feasible.
If the test networks are successful, the Dutch initiative, which has the support of substantial European investment, might make the dream of a continent-wide quantum internet one that protects everything from financial transactions to national security, a reality within the next ten years.
