Quantum Computing
Quantum Computing has been an interesting subject to me for quite a few years. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states.
Although the idea of quantum computing has been hypothetical for quite a while, the actual development is just in its infancy. Quantum computing could theoretically work problems that standard computers can't solve.
Quantum simulation could change the way problems are solved. Using quantum simulations can help to explain the expectations and behaviors of atoms. One of the things that must be overcome is pulse shaping. The ability to make sure the bandwidth doesn't increase past the bandwidth channel. If it does then distortion will occur.
In trying to comprehend the idea of Superposition, Erwin Shrodinger proposed what is known as the Schrodinger's Cat thought experiment, back in 1935. He came up with the concept as what most people consider to be a paradox.
A cat is both alive and dead at the same time because of a state known as quantum superposition. The possibility of this comes from a random subatomic event that may or may not occur. It's been used many times in attempts to explain and teach quantum mechanics.
A cat is placed in a box or chamber. Inside is also a small bit of radioactive substance that could or could not have an atom decay within an hour. There are equal probabilities that it would decay or it would not decay. If it does decay then a hammer is released and it smashes a flask of acid and kills the cat. If it doesn't decay then the cat continues to live. Superposition indicates that as long as the cat is not observed, it is both alive and dead at the same time. Once it is observed the state is defined.
Schrodinger's statement is "When does a quantum system stop existing as a superposition of states and become one or the other?"
These new concepts and the way we use them would change the form of computing forever. A fascinating subject that time and effort are worth investing in.
