Abstract

The dream of a space-based, nighunhackable quantum Internet may now be closer to reality, thanks to new experiments with Chinese and Europeansatellites. Quantum physics makes possible a strange phenomenon known as entanglement. Essentially, two or more particles such as photons that get linked or "entangled" can, in theory, influence each other simultaneously no matter how far apart they are. Entanglement is essential to the workings of quantum computers, the networks that would connect them, and the most sophisticated kinds of quantum cryptography-a theoretically unhackable means of information exchange.

QUANTUM ENTANGLEMENT OF CONCENTRIC UNIVERSES IN DYNAMICAL SYSTEMS

Adi Al A’assam

Quantum entanglement is a group of particles that interact indirectly with other particles that are close or distant in space. As for qualitative entanglement, it is social and cosmic phenomena that are close or distant in space and also interact indirectly with similar phenomena. Our interpretation is that cosmic events are mostly coordinated in advance, similar to movie scenes, and that the universe exists within other concentric universes. Descition Quantum entanglement is that a particle rotates clockwise so that it is physically linked, no matter how far apart, to another particle that rotates counterclockwise, meaning that the total spin is zero. Einstein and his ilk went to the impossibility of such quantum behavior and described it as a ghostly action from a distance, but they differed. Rather, they proved that the interpretations of quantum mechanics are realistic and that the effect between particles separated by enormous astronomical distances occurs instantaneously, such that the speed of light cannot explain it. This was captured by researchers from the University of Glasgow in the year. The first image of quantum entanglement is known as entanglement, and it is hoped that such entanglement will contribute to advancing communications and computing. On our part, we can add that entanglement is to make two similar things have a kind of difference, but there is a strong connection between them. Particles are usually identical, but the difference is in the opposite rotation of each of them, and the connection is in these opposite particles. We have found similarity in the attraction between things, each of which has mass and attracts the other, and this is the connection. The law of gravity is subject to a mathematical law, and it is the one who lacks something that does not give it. If there is nothing on Earth similar to what is on the moon, then there cannot be an attraction between them. We can call it gravitational entanglement. There is an equivalent entanglement represented by the equivalence of energy and mass E=mc^2.

Transmission of Entangled Photons over a High-Loss Free-Space Channel

Rupert Ursin, B. Bhawal

Entanglement is an essential phenomenon of quantum mechanics. Two entangled particles, photons for example, will individually yield random results upon being measured, but these results will always be perfectly correlated, no matter how far the two particles are separated from each other. Entanglement has been proven to be at the heart of a wide range of fundamental quantum effects and it drives exciting practical applications, such as quantum cryptography, quantum teleportation and quantum computing [1], which would be impossible in a world limited to classical physics. A team of researchers from the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna and the University of Vienna, led by Anton Zeilinger, has now reported the successful transmission of entangled photon pairs between two Canary Islands, bridging a distance of 144 km and a two-photon attenuation of almost ten million to one. The result, published in Nature Physics [2], is so far the most convincing demonstration to perform experiments with entangled photons in space.

LOOKING AT THE QUANTUM INTERNET

Paolo Di Sia

The future of the Internet and of computer communication goes through modern physics. Using the new properties of quantum mechanics, various research laboratories around the world are building prototypes of “quantum networks”, a new way that uses some quantum physics principles to deliver information packets. In the near future our data will be able to travel on the Internet at very high speed, also greater than the speed of light, thanks to the quantum network. Independent research groups have already been able to demonstrate the entanglement of photons on fiber optic networks in China and Canada. The result can be considered as the first step for the realization of quantum telematic networks on a metropolitan scale and the connection at large distances of future computers based on quantum physics. But the quantum computer will be  such a   powerful system that can  even damage the security of our systems and networks as we know them today, as well as to personal privacy, already threatened  by current network rules.

Unhackable Quantum Internet: A Revolutionary Innovation of the 21st Century.

Dr. A.SHAJI GEORGE, A.S.HOVAN GEORGE, Digvijay Pandey

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.

On Quantum Entanglement

Bertrand Wong

Quantum entanglement, a term coined by Erwin Schrodinger in 1935, is a mechanical phenomenon at the quantum level wherein the quantum states of two (or more) particles have to be described with reference to each other though these particles may be spatially separated. This phenomenon leads to paradox and has puzzled us for a long time. The behaviour of entangled particles is apparently inexplicable, incomprehensible and like magic at work. Locality has been a reliable and fruitful principle which has guided us to the triumphs of twentieth century physics. But the consequences of the local laws in quantum theory could seem “spooky” and nonlocal, with some theorists questioning locality itself. Could two subatomic particles on opposite sides of the universe be really instantaneously connected? Is any theory which predicts such a connection essentially flawed or incomplete? Are the results of experiments which demonstrate such a connection being misinterpreted? These questions challenge our most basic concepts of spatial distance and time. Modern physics is in the process of dismantling the space all around us and the universe will never be the same. Quantum entanglement involves the utilisation of cutting edge technology and will bring great benefits to society. This paper traces the development of quantum entanglement and presents some possible explanations for the strange behaviour of entangled particles.

Quantum Entanglement-Based Physical Simulation Algorithm

Jincheng Zhang

Quantum entanglement, a bizarre phenomenon where two or more particles become linked in such a way that they share the same fate no matter how far apart they are, has captivated physicists and philosophers alike. Harnessing this quantum connection offers a potentially revolutionary approach to physical simulation, surpassing the limitations of classical computational methods. This paper proposes a novel physical simulation algorithm predicated on the principles of quantum entanglement, aiming to achieve unprecedented accuracy in simulating complex quantum systems. We outline the core mechanism, detail the theoretical foundations, and explore the potential implications of this approach. The core claim centers around the design of a quantum entanglement-based algorithm capable of revealing subtle physical laws and offering a fundamentally deeper understanding of quantum phenomena.
