Quantum future

[tw]

It appears Intel is finally hitting the brick wall of silicon based, CMOS transistors. Same problem will be happening for other IC manufacturers.

Innovation is about constantly advancing a technology until it must be obsoleted by a fundamentally new technology. Bipolar was obsoleted by CMOS. CMOS might be replaced by transistors based upon quantum physics.

Same is true of communication. Currently, encryption is based upon factoring technologies. RSM is the benchmark is so many secure transmission. IOW your message is secure because you can prove to the other guy who you are AND you 'hope' your communications are not compromised. Same principles found in Identify Theft protection.

Your communication is secure only if you can prove who you are and DETECT compromised communications. Quantum encryption promised to provide this signifcant advantage.

Currently operating are six nodes in a quantum based system between Harvard, Boston U, and BBN (considered the founders of internet hardware). This demonstraton uses quantum encryption on photons. Unlike conventional encryption, this secure communication should be able to detect if another has accessed (or tried to access) a communication.

Quantum physics was so mysterious that early scientists doubted while continuing work on the science. Even Einstien remained in disbelief. And yet quantum physics may be the next generation of computer and communication science.

Recently demonstrated in both Europe and N America was teleportation - in its simplest form. Again, quantum physics.
