What is the Quantum Internet of Things?
Picture a world where the technology we have today is inconsequential, a world where the internet is revolutionized and communication is invincible, a world where quantum internet reigns supreme. Sounds like a scene out of a sci-fi movie, right? Well, this reality is not too far away from unfolding. The emergence of quantum computing and the race towards building a quantum internet promises an extraordinary future. In this post, we’ll explore the possibilities of the quantum internet, its potential applications, and the advancements made towards its realization.
The Quantum Internet of Things
Quantum internet or QI is a hypothetical extension of the modern internet that would use quantum computing to deliver unprecedented levels of security and speed, enabling applications that are currently impossible. The current internet relies on a system of continuous transmission of information, traveling on cables, satellite beams, and radio waves. As a result, data can be subject to interception and leading to data breaches, making it vulnerable to cyberattacks.
In contrast, the QI addresses these issues by taking advantage of quantum mechanics to encode and transmit data, making the transmission of secure communication possible. It employs an innovative approach of exchanging qubits – the basic unit of quantum information – between two quantum devices. The qubit’s basic states, a 0, a 1, or a combination of both, can be manipulated, used for information processing, and used for transmitting information.
The capability of qubits allows for the creation of unhackable data transmission, which is an essential feature of the quantum internet. Through quantum cryptography, quantum keys can be generated and exchanged securely between devices without interference from third parties. By using quantum encryption, data can be protected in a way that would be impossible to obtain the keys that would allow decrypting the information.
Breaking Down the Advancements Made Towards Quantum Internet
Several countries worldwide are actively investing in developing the infrastructure for the quantum internet. In 2019, Chinese scientists demonstrated a quantum key distribution through a satellite, establishing two ground stations separated by 1,120 km.
The demonstration was a big step towards a global quantum network, connecting space-based and ground-based quantum devices. Until then, researchers had been limited to testing transmission over much shorter distances due to the absorption and falling of photons in the atmosphere.
The US government also plans to develop an unhackable quantum internet, investing over $700 million in research for quantum computing over the next five years. In November 2020, the Department of Energy’s Argonne National Laboratory launched its Quantum Information Science (QIS) research initiative, which aims to develop quantum networking testbeds, quantum algorithms, and hardware. They also intend to partner with academia, industry, and other national laboratories to accelerate the development of quantum technology, including quantum networking.
Europe is also leading the race, with investments in quantum technology reaching over $1 billion by 2020. Fourteen EU countries banded together to fund a Quantum Flagship program, working towards building a commercial quantum computer, and a quantum internet by 2030.
What Are the Potential Applications of Quantum Internet?
The QI has the potential to revolutionize several industries due to its unique capabilities. Let’s explore some of the applications of the quantum internet:
1. Quantum Cryptography
The quantum internet can make communication between devices invincible to hacking. Quantum cryptography can be used to create unconditionally secure communication links, which could be useful in transmitting private messages, banking transactions, and government secrets.
2. Medical Research
Quantum computers’ processing power can simulate intricate biological systems that a classical computer would be unable to model. By doing so, they could enable medical researchers to better understand complex diseases and create new drugs by modeling the efficacy of different molecules.
3. Self-Driving Cars
This technology could revolutionize self-driving cars as quantum sensors could detect obstacles faster and more efficiently, leading to faster response times. This would translate into safer journeys and fewer accidents on the road, saving countless lives.
4. Environmental Monitoring
The QI has tremendous potential in environmental monitoring. Quantum sensors can be used to detect even the slightest changes in environmental factors like temperature, pressure, and electromagnetic fields that could be used to predict natural disasters like earthquakes, volcanic explosions, and other environmental factors.
5. Financial Trading
Quantum computers can process vast amounts of data in a fraction of the time it takes conventional computers. In financial trading, this means faster and more efficient decision-making, leading to more profitable returns on investment.
Conclusion
The quantum internet promises to herald a new era of innovation, with unimaginable possibilities. Its potential applications range from healthcare to finance, with infinite possibilities. We’re beginning to see strides being made towards its realization, with countries investing hefty sums to ensure they’re at the forefront of this remarkable development. Consequently, the future may be quantum-powered, with the internet of things being the gateway to a more connected, secure, and faster world. It may still be some years before we see the quantum internet becoming widely accessible, but the advancements being made leave us with much to anticipate.
