Interesting Issue for Cryptography and quantum computing

[cesar.ma...@gmail.com]

I found and interesting article that talks about a big issue for computer security.

As we know, the basis for current encryption algorithms is that they while are not impossible to crack, they are 'practically' impossible to crack on the basis that a computer would take millions of years to do so.

However, now with the upcoming of quantum computing, what a normal binary computer would take millions of years to crack, a quantum computer could in a few minutes.

Apparently this is a big upcoming issue in security and an interesting topic, or so I found.

At the same time however, encryption algorithms created with quantum computers would create the most crypto secure algorithms at the same time (one of them being Quantum Key Distribution)   which is theoretically a completely secure method of key distribution, and relies on quantum entanglement to transmit information in quantum states, or qbits. 

No idea how this works, but I imagine that at some point every computer would need have quantum computing power? Or have a quantum chip used just for encryption and security measures? Similar to how we have encryption chips in computers now (I think this was mentioned in class).

I didn't research that deep into it to understand how it would work, but found it interesting especially for this class.

Here is a video on the subject of how quantum computers breaks encryption as we know it but also fixes the issue by using a new method of encryption.
