Shor’s algorithm can use a fairly fault tolerant Quantum Computer to ease through breaking RSA Protocols.
Quantum Computing is moving at a fast pace. We are probably at the vacuum tube stage of classical computers (analogy to Quantum Computers), but what they did not have back in the day, we have now – exponentially large bandwidth for information reception and transmission.
This will definitely accelerate the process, and though the popular opinion is to see a fairly functional Quantum computer by the 2030’s, I think this might occur by 2025, at-least on the cloud. Some free systems are already available with IBM’s cloud services today.
Quantum computers will surely change the way that we look at Cryptography and cyber security. Today, we consider Blockchain to be one of the most robust, secure and cost effective ways to store sensitive data. As we move into an era where data is becoming an entirely different asset class, it’s value has risen exponentially in the past.
Most experts have suggested methods to add a quantum layer on top of the current blockchain structure by creating a layer of quantum cryptography over a traditional blockchain. One of the popular means is to use a random series of photon transmitters and generators to send and receive photons in upto four states at a time. At the time of reception and transmission, the messages are compared to the primer and a trust is established. The compared message is basically the key to the primer, allowing a secure connection to be established to create a blockchain node or copy. Though this computationally flawless, we can speculate breaches after a connection is established or malicious middleware to skip the quantum protocol all together leaving the blockchain exposed to a quantum network attack.
However, we think it’s fundamentally necessary to change blockchain as a whole by creating a new type of structure of blockchain, that is enabled by quantum entanglement. These entangled particles can be used to represent the basis of continuity or the “Next Block” hashing in the traditional blockchain. Quantum entanglement is not bound by time or space, that means it is possible to not only separate entangled particles over space, you can also, given enough time, entangle particles across the past or future.
While it is child’s play for a fairly powerful quantum computer to break a traditional blockchain protocol, with Quantum Entanglement, if a malicious user / bot tries to observe or access information tied to one quantum particle, then it’s pair linkage is instantly destroyed, causing the entire copy of the block to become lost in time or space, the information becomes abstract in entropy with no value associated to it. So hey, there is a way to counter Quantum computers using Quantum Physics.
As we dive deeper intoIBM‘s quantum computing advances, we atErebor Cyberneticshope to prototype a feasible version of the same. Thank you IBM for providing the QISKit for free!You can download it hereand develop primitive algorithms to run on IBM-Q.
I’ve spent most of my weekend playing around with IBM-Q and I think we have barely even scratched the surface of the boons and banes that Quantum Physics and Quantum Computing can bestow upon our species over time. It’s truly an amazing time to be alive.
Here’s to the future of computing!
