Fascinating! Quantum entanglement file transfer could change how we think about and handle data transfer. Will it be possible to transfer files over vast distances instantly?

Unfortunately, it's not that simple. While entangled particles can instantly affect each other, transferring files still requires a physical medium or signal to connect the two points (like optical fibers, for instance).

The theory and technology are still up for debate and research. Although totally possible, we may have to wait decades until we see real-life use cases.

This sounds a lot like Star Trek's 'subspace' communication. Is there a chance it may become a reality soon?

What kind of risks does this pose to data privacy, if packets are literally becoming entangled quantum-wise? Isn't there a risk of data being copied/intercepted?

It is worth mentioning the no-cloning theorem. Since data cannot be cloned in a quantum state without disturbing the original, it adds a layer of security by default.

@DataScienceGuru: Valid question. Entangled particles share properties in a probabilistic sense; thus, data is not literally copied, making interception more difficult. However, since it's a nascent field, researchers have yet to find out what vulnerabilities could emerge.
