quantum-mechanical phenomena, such as superposition andentanglement, to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses qubits (quantum bits), which can be in superpositionsof states.

There exist quantum algorithms, such as Simon's algorithm, which run faster than any possible probabilistic classical algorithm.[8] Given sufficient computational resources, however, a classical computer could be made to simulate any quantum algorithm; quantum computation does not violate the Church–Turing thesis.[9]A quantum computer is a computation device that makes direct use ofquantum-mechanical phenomena, such as superposition andentanglement, to perform operations on data.[1] Quantum computers are different from digital computers based on transistors.

...What are we made of???
Throughout the years the Quantum Mechanic model has evolved many times. This evolution has taken place after every major discovery in Quantum Mechanics. The current Quantum mechanic model is by far the most accurate example of an atom and how it works. Currently the model depicts a proton (or more than one depending on the atom) and neutron in the nucleus and a an electron rotating around the nucleus in an energy level, or an...

...Paper on Quantum Cryptography
1.Introduction
"Quantum cryptography is the only approach to privacy ever proposed that allows two parties to communicate with provably perfect secrecy under the nose of an eavesdropper endowed with unlimited computational power and whose technology is limited by nothing but the fundamental laws of nature."
The word quantum refers to the most fundamental behaviour of the smallest...

...The Impossibility of Quantum Teleportation due to Heisenberg’s Principle of Uncertainty
The classical concept of teleportation is simple in theory, but much harder in practice. Imagine two boxes; namely Box A and Box B. The aim is simply to get the contents of Box A into Box B. This is done by gathering all the information of the contents of Box A and sending it to Box B, where the information may be used to recreate it. In theory this is quite simple, ignoring the low...

Quantum entanglement is ubiquitous, appears everywhere in the microscopic world
(See, e.g., Durt, 2004; Brooks, 2005) and under some circumstances manifests itself
Macroscopically (Arnesen, et al, 2001; Ghost et al, 2003 & Julsgaard et al, 2001). Indeed, it

...The Quantum Mechanical Model of the Atom
Energy Is Quantized
After Max Planck determined that energy is released and absorbed by atoms in certain fixed amounts known as quanta, Albert Einstein took his work a step further, determining that radiant energy is also quantized—he called the discrete energy packets photons. Einstein’s theory was that electromagnetic radiation (light, for example) has characteristics of both a wave and a stream of particles.
The Bohr Model of...

...future is the thing that takes a lot of our time and efforts being computer oriented.
We have to imagine, try to figure out what the future will bring us.
We are supposed to lead our generation in looking for new and life enhancing technologies to make man's life easier and more enjoyable.
