Using quantum-secured communication for data transfering

In summary, quantum entanglement is a way of transferring information using quantum states. It is possible to use it to send information between different computers, or even across continents.

Hello!
I am wondering if it is theoretically possible to allow a means of data transfer (or internet, etc.) by the idea of quantum entanglement. Correct me if I make any errors in understanding. But, by what I understand, in essence you could for instance run a computation on a quantum computer of sorts and in turn use a separate module to "clone" this computation, or literally a movement of entangled particles, and then allow the connecting "clone" to be on a "server" and this server could "clone" the computation or result and then send that result via current internet to another computer, or even by giving an instruction set to another quantum computer that allows it to create an entangled environment in which it is now cloning the same computation/calculation.

Here is a relevant piece on a similar idea:
Quantum entanglement, to Erwin Schroedinger the essential feature of quantum mechanics, has become a central resource in various quantum communication protocols including quantum cryptography and quantum teleportation. From a fundamental point of view what is exploited in these experiments is the very fact which led Schroedinger to his statement namely that in entangled states joint properties of the entangled systems may be well defined while the individual subsystems may carry no information at all. In entanglementbased quantum cryptography it leads to the most elegant possible solution of the classic key distribution problem. It implies that the key comes into existence at spatially distant location at the same time and does not need to be transported. A number recent developments include for example highly efficient, robust and stable sources of entangled photons with a broad bandwidth of desired features. Also, entanglement-based quantum cryptography is successfully joining other methods in the work towards demonstrating quantum key distribution networks. Along that line recently decoy-state quantum cryptography over a distance of 144 km between two Canary Islands was demonstrated successfully. Such experiments also open up the possibility of quantum communication on a really large scale using LEO satellites. Another important possible future branch of quantum communication involves quantum repeaters in order to cover larger distances with entangled states. Recently the connection of two fully independent lasers in an entanglement swapping experiment did demonstrate that the timing control of such systems on a femtosecond time scale is possible. A related development includes recent demonstrations of all-optical one-way quantum computation schemes with the extremely short cycle time of only 100 nanoseconds.

Is this way off or is something like this viable? Feel free to make corrections and discuss this in the comments.

Thank you!

The only way to "clone" a quantum state reliably would be to know exactly what that state is beforehand.
The no-cloning theorem shows it's not possible to clone an unknown quantum state without this extra info.

That being said, there are ways of transferring information using quantum entanglement.
Three ways that come to mind are:
Entanglement-based quantum key distribution
Quantum dense coding
Quantum Illumination

Thanks, I will definitely study these topics!
 

Related to Using quantum-secured communication for data transfering

1. What is quantum-secured communication?

Quantum-secured communication is a method of sending and receiving information that uses the principles of quantum mechanics to ensure the security and privacy of the data being transferred.

2. How does quantum-secured communication work?

Quantum-secured communication uses the properties of quantum particles, such as photons, to encode and transmit information. This method involves creating a shared key between the sender and receiver, which is then used to encrypt and decrypt the data being transferred.

3. What are the advantages of using quantum-secured communication?

One of the main advantages of quantum-secured communication is its high level of security. The use of quantum mechanics makes it virtually impossible for hackers to intercept and decode the information being transferred. Additionally, quantum-secured communication is also resistant to eavesdropping and other forms of cyber attacks.

4. Are there any drawbacks to using quantum-secured communication?

One potential drawback of quantum-secured communication is its reliance on advanced technology, which can be expensive and difficult to implement on a large scale. Additionally, the protocols for quantum-secured communication are still being developed and may not be fully standardized yet.

5. How is quantum-secured communication being used in real-world applications?

Quantum-secured communication is currently being used in various industries, including banking, government, and healthcare, to protect sensitive data from cyber threats. It is also being explored for use in satellite communication, where secure transmission of data is critical.
