When we think of the Internet today, we might think that everything is perfect; but the reality is that the classical Internet has problems such as low security, limited speed and vulnerability to cyber attacks. Now imagine having an Internet that works based on quantum laws; something called the Quantum Internet.
Internet based on entanglement
In the quantum Internet, data is transmitted not as bits of 0 and 1, but as qubits. A phenomenon called quantum entanglement causes two particles to reflect each other’s state instantaneously, even thousands of kilometers apart. This means that there is no way to eavesdrop or manipulate data.
Key advantages of the quantum Internet
Absolute security: Any attempt to infiltrate the data causes a change in the quantum state and will be immediately detectable.
High speed: The ability to transmit data without the limitations common in fiber optics or radio waves.
Connecting quantum supercomputers: It is possible to build a global network of quantum computers that will be more powerful than all of today’s classical supercomputers combined.
Global projects
China has launched a satellite called Micius that can transmit quantum keys across continents.
The European Union has also launched a large-scale project to create a quantum internet test network in several countries.
In the United States, national laboratories and universities are working on building quantum infrastructure.
Many experts believe that the quantum internet will be the same revolution that the classical internet created in the 1990s.
