Quantum Computer: How close are we?
As I have mentioned in my previous articles, the RSA and DES will instantly become obsolete if the time has come that Quantum Computers have been fully developed and therefore all fully secured and reliable communication systems like securing the data being entered in an Accounting Software has only one encryption method to rely on and that is of course the Quantum Cryptography. But let us think of today and how close are we into making this dream a reality.So, I googled “Quantum Computer News” and I have managed to read only the top listed site Science Daily . It was obvious that the website contains the most number of updates related to current developments on Quantum Computers and is enough to satisfy my thirst.Of course this is only my opinion, upon reading the latest news, I think that the current situation is much like the situation wherein Allan Turing(the person who was credited to be the first person to have invented the digital computer) is in the process of designing the first digital computer and that was probably in the late 30’s to mid 40’s and obviously during the 2nd World War.So my conclusion is there is so much work to do but we are absolutely going to be there in the not so distant future. Another question again appeared on my mind and that is “Can we harness the enormous power of this Quantum Computer to make a self-aware Accounting Software?”. So probably I’ll tell you what I think in my future articles.
Quantum Cryptography depends entirely on polarization of the photon and photons was the main cause of the pole-shifting of our planet which caused the almost wiping out of our civilization as mentioned in the movie “2012″. I hate photons!
Is it Allan Turing not the US Military? As far as I can remember, our textbook in college(late 80’s) says the ENIAC was the first Digital Computer assembled by the US military after the 2nd World War. I can only remember Allan Turing as the father of Artificial Intelligence.
The book that I am reading confirms that Alan Turing was credited to have invented the first programmable machine or the modern computer. But that book was published in the late 90’s. So probably you are not updated…Alan Turing’s invention was probably recognized in the late 90’s.
Cheers for the fantastic article - I had fun reading it! I always love looking at your blog.
The data entered and processed in Accounting Software and other related activities where data and information should be protected and concealed from the prying eyes of thiefs, scammers, criminals, corrupt regimes will be at risk the moment this Quantum Computer will be developed and be sold in the market just like how current pc’s, Accounting Software are being sold. If you have noticed, secured communications has somehow prevented corrupt governments in the far east and africa from killing families and whole villages.
How powerful really is this Quantum Computer? Can it really be able to decrypt the RSA and DES in just 1 second? A task that can be accomplished by 100 million networked 1GHz PC’s in 5 times the age of the Universe? I doubt it very much.
@Accounting Software Opinion: That is the main motivitation behind all these buzz about Quantum Computers. It is expected that Quantum Computers could easily decrypt the RSA and DES making these 2 reliable encryption systems obsolete. And probably it will. That can only be proven if the Quantum Computer has already been developed.
Pls stop mentioning DES. DES(Data Encryption Standard) was invented by some IBM Computer Scientists during the time when most of the world’s best Mathematicians, Computer Scientists and Cryptologists are on a tight race in finding the solution to the Key Distribution System. DES is not a breakthrough…it was the RSA that made a huge impact and solved the Key Distribution System making our communication systems highly secured and protecting Accounting Software data reliably. DES is just a variant of the Enigma cypher and still relies on a key that has to be sent to the recipient to decrypt the message.
The DES is still widely used today together with the RSA. RSA is used to decrypt the key used to decrypt the data encrypted with DES. Why is this so? If the whole message or data is encrypted with RSA, the decryption process is very slow if the message is let’s 100 pages or 1mb of Accounting Software data. That is why DES is used because it is a lot faster to decrypt the message. DES is just as strong as the RSA but it did not solved the key distribution system.
There is a huge possibility that Quantum Computers can instantly decrypt the RSA. The Multi Universe approach of Quantum Theory says that at sub-atomic level, the behavior does not obeys the Laws of Physics as we know it…photons are supposed to travel in straight lines but they don’t..they appear to travel in all direction at the same time which could be explained by saying the universe around each photons tend to split infinitely and the photons enters each one of these universes at the same time. And because of quantum theory, lots of useful devices were invented the most popular of them all is the cd player and vcd/dvd/blue-ray players. The distribution of Accounting Software would not have so convenient with cd’s right?
Wow, this is the first I got to read about this Quantum Theory thing. As a child, I used to watch a lot to cartoons and several movies who’s theme is about parallel universe and also had watched Twilight Zone. The writer of those shows I watched must have been inspired by this Quantum Theory.
