Quantum Computing

I’ve been really getting into the world of Quantum computing. It looks like the Information Age is TRULY in its infancy. Quantum computing which scientist are now predicting will be available by around 2020 will be one of many systems that change everything about the human species. It is an exciting time to be alive for certain:

What is ridiculous about these systems is that they will be so powerfull that they will be able to break AES, DES, 3DES and other cryptological methods that are based on “difficult math” such as factoring prime numbers. Once quantum computers get going, Internet encryption will be irrelevant. That means credit card, bank and any thing with classical encryption will no longer be safe because quantum computers will be sniff out all the encrypted traffic (this is already doable) and then crack the encrypted data with something like a quantum L0ptCrack.

Quantum Key Distributions (part 1)

The NIST has an page that talks about Quantum Key Distribution:

Quantum encryption systems use lasers to generate individual pulses of light called photons. Each photon is sent in one of two modes, either vertical/horizontal, or plus 45 degrees/minus 45 degrees. Within each mode, one orientation represents the digital value 0, and the other represents the digital value 1. To visualize how this works, imagine that each photon is a tiny envelope moving perpendicular to the ground (vertical=1), parallel to the ground (horizontal=0), tilted at 45 degrees to the right (plus 45 degrees =1) or tilted 45 degrees to the left (minus 45 degrees=0). NIST 

Its almost scary how much has been done in relatively so little time in the “Information Age” and its only just the beginning.  

The possibilities are unimaginable.  I thought it was a bit extreme when I read an Author C. Clarke sci-fi novel called, Light of Other Days in which people can send messages directly from brain to brain (some sort of brain to brain Internet) via a device that sends messages on a subatomic level.  Now it doesn’t sound so strange anymore (well, ok, its still strange but it seem possible now).

Here are some mind blowing articles about quantum entanglement:

Quantum Teleportation of data (actually it’s the instantaneous transfer of quantum states, but teleportation sounds cooler)
      The thing is that it has already being done:

Quantum Entanglement as an explanation for so called psychic phenomenon:
      Highly controversial as parapsychology is the “leprosy” of
      science.  Just a hypothesis but interesting:
