Quantum Encryption is a dream that is rapidly coming true (University of Science and Technology China). At this level, it can make data secure and virtually impossible to hack. This will put the NSA back to the stone age where they belong. Crimes will have to be solved the old fashion way instead of hacking someone’s cell phone to figure out where their bank accounts are and did they pay their tax for the shoes they are wearing.
The Chinese satellite Micius has sent a quantum-encrypted dataset between China and Austria. The Chinese are leading the way to what may prove to be a global quantum internet. They launched Micius in August 2016, to experiment with quantum communications and encryption. Conventional communications satellites transmit information via radio or microwave signals. Micius uses quantum-entangled photons to effectively “teleport” information. This means SPEED that is almost instantaneous while quantum communications are extremely secure and will beat everything – yes even blockchain.
OK. That may sound like Star Trek and beam me up, Scotty! Well, what this amounts to two photons are inextricably linked, meaning if a user knows the state of one particle they can infer the state of the other, no matter how far apart they are. Last year, Micius beat the quantum entanglement distance record, sending a message over a distance of 746 miles.
It works in the same way as Schrödinger’s famous thought experiment, involving a cat in a quantum superposition of being simultaneously both alive and dead. It’s not until an observer peeks into the box and checks on the cat that the superposition collapses into one state or the other. Schrödinger highlighted the bizarre nature of quantum superpositions, in which a quantum system such as an atom or photon can exist as a combination of multiple states corresponding to different possible outcomes. The prevailing theory, called the Copenhagen interpretation, said that a quantum system remained in this superposition until it interacted with, or was observed by, the external world, at which time the superposition collapses into one or another of the possible definite states. The EPR (Einstein, Podolsky, and Rosen) in a 1935 experiment showed that a system with multiple particles separated by large distances could be in such a superposition.
Quantum superposition is a fundamental principle of quantum mechanics. It states that, much like waves in classical physics, any two (or more) quantum states can be added together (“superposed”) and the result will be another valid quantum state; and conversely, that every quantum state can be represented as a sum of two or more other distinct states. This also surfaces in the cyclical analysis that I have observed and call the Cycle Inversion.
Here, a message is sent as individual photons that are in quantum superposition states. That means in data terms, those photons represent both ones and zeroes at the same time. The message is coded and decoded through devices at each end. They essentially collapse each incoming photon into the required state, one or zero. If an unauthorized person even tries to intercept the message along the way, the very act of observing it will cause the superposition of each photon to collapse into a random state, garbling the message for the hacker and alerting the intended recipient to the breach.
This is going to change everything. It is interesting that China is ahead of the game. Seems to be spot on with our computer forecasts.
