Building a quantum internet is a key ambition for many countries around the world as such a breakthrough will give them competitive advantage in a promising disruptive technology, and opens a new world of innovations and unlimited possibilities. Recently the US Department of Energy published the first blueprint of its kind, laying out a step-by-step strategy to make the quantum internet dream come true. A quantum internet would be able to transmit large volumes of data across immense distances at a rate that exceeds the speed of light. Academics, researchers, and IT professionals will need to create devices for the infrastructure of quantum internet including: quantum routers, repeaters, gateways, hubs, and other quantum tools. A whole new industry will be born based on the idea of a quantum internet existing in parallel with the current ecosystem of companies the authors have in a regular internet.
Quantum cryptography uses physics to develop a cryptosystem completely secure against being compromised without knowledge of the sender or the receiver of the messages. Regular, non-quantum encryption can work in a variety of ways, but, generally, a message is scrambled and can only be unscrambled using a secret key. Cracking the private key in a modern cryptosystem would generally require figuring out the factors of a number that is the product of two insanely huge prime numbers. The numbers are chosen to be so large that, with the given processing power of computers. But, in practice, quantum cryptography comes with its own load of weaknesses. It was recognized in 2010, for instance, that a hacker could blind a detector with a strong pulse, rendering it unable to see the secret-keeping photons.

Quantum cryptography uses physics to develop a cryptosystem completely secure against being compromised, without the sender or the receiver of messages being known. The word quantum itself refers to the most fundamental behavior of the smallest particles of matter and energy. Quantum cryptography is different from traditional cryptographic systems in that it relies more on physics, rather than mathematics, as a key aspect of its security model. Essentially, quantum cryptography is based on the usage of individual particles/waves of light (photon) and their intrinsic quantum properties to develop an unbreakable cryptosystem (because it is impossible to measure the quantum state of any system without disturbing that system). Regular, non-quantum encryption can work in a variety of ways but generally a message is scrambled and can only be unscrambled using a secret key. The trick is to make sure that whomever you’re trying to hide your communication from doesn’t get their hands on your secret key.
The concept of the quantum internet shall be to profoundly improve Internet technology by allowing quantum communication between any two points on Earth. Quantum technology, as well as research, will open up the door to all types of new possibilities and opportunities. Some of those possibilities include the speed of communications, Although the first implementations of small-scale quantum networks are anticipated in the foreseeable future, scaling those networks presents enormous challenges for fields such as physics, computer science as well as engineering. This has important implications for a wide variety of fields from weather forecasting to healthcare research as well as the development of Artificial Intelligence, not to mention that the previously known effect on cybersecurity and the ability to break existing encryption methods. At this moment, we are convinced that the quantum Internet will have the ability to do incredible things, considerably faster than the traditional Internet. The great advantage of quantum communication is that it is much more secure than everything else. The internet could look ahead to a bright future with the new quantum technology hacking proof exchange of information as well as superfast data processing is going to become possible. Such a significant breakthrough will provide them with a competitive edge in a hopeful technology and opens a new universe of innovations and unlimited opportunities. In this paper, we offer an overview of the benefits anticipated on the Quantum Internet. In this paper, the author presents the fundamental ideas of quantum physics and describes the concepts of quantum repeaters, and the mechanism of a quantum Internet. Particular attention is given not just to the technical problems implicated, but additionally to the potential impact on society. The purpose of this paper is to provide a straightforward understanding of the Quantum Internet as well as how it developed, and the advantages of Quantum Internet.
The application of internet has spiked up in the present-day scenario, as the exchange of information made between two parties happens in public environment. Hence privacy of information plays an important role in our day to day life. There have been incredible developments made in the field of cryptography resulting in modern cryptography at its zenith. Quantum computers are one among them creating fear into security agencies across the world. Solving the complex mathematical calculations is uncomplicated using quantum computers which results in breaking the keys of modern cryptography, which cannot be broken using classical computers. The concept of quantum physics, into the cryptographic world has resulted in the advancement of quantum cryptography. This technique utilizes the idea of key generation by photons, and communicates between peer entities by secured channel. Quantum cryptography adapts quantum mechanical principles like Heisenberg Uncertainty principle and photon polarization principle to provide secure communication between two parties. This article focuses on generation of a secret shared key, later converted into Quantum bits (Qbits) and transmitted to the receiver securely.
