Sure, pure research is needed, I think everybody would agree with that statement...but how much of the pure research gets funded through taxpayers money is a real issue. And how do we select what is worth funding or what is not. Hopefully neither @pixeies or @lionlair are not suggesting that every scientist researches whatever he/she feels like it? (I end up paying for it)...Kris

Pure research is needed to create new abilities. When research is dependent upon the final product - then much of what we know would have never been discovered. When forced under product needs, only products along that line are developed or nothing at all since the concept never sees the light of day. Martin

To @pixies: Why would say it is a pity to justify the research? Do you really expect taxpayers to pay for research which serves no practical applications at some point? Kris

Now I understand why in so many sic-fi movies the computers were made of crystals (Superman and Star Gate, for examples.) Joking aside, quantum entanglement hold so much more potential than just encrypt communications. It is a pity to see physicists have to justify their research with a practical applications.

Think about it this simple way: if you have some bits of your key entangled with the data you need secured, then the hacker with the different key will just get a different (meaningless) data without being able to tell that

I could not understand how this new quantum memory technology will make the future networks SECURE. Most of the other technologies the hackers will go one step ahead to break the security of even these networks. Can somebody enlighten me on this?

Solid state shrinkage is the reduction of size for a material that already is solid. Railway tracks get smaller when it's cold. http://www.healthproductreviewers.com/lifecell-skin-cream-review.html

I guess Heisenberg's uncertainty principle is disproven? If not, how can a quantum memory work? It seems like the mere act of reading a quantum memory value would also cause the value to change.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
