GS1140 Problem Solving Theory
Module Three: Generating Solutions Using Futuring:
As we progress in our technological world where everyone is interested in the next iPhone or Samsung Galaxy, quantum computers are still moving forward. It seems that only computer "nerds" seem to care and understand this wonder. What if all of the theories, concepts, and everything else that makes up what quantum computers are and will be, is presented in a way that everyone can understand. The way that quantum computers can be divided is into three main areas: quantum physics, quantum bits or (qubits), and their future goals.
To better understand how quantum computers work, you need to start with what clearly defines a quantum computer: A quantum computer is a computer design which uses the principles of quantum physics to increase the computational power beyond what is attainable by a traditional computer. Quantum computers use two fundamental principles of quantum physics: superposition and entanglement. Quantum superposition is where the state of a physical system exists in all possible states at the same time. Then the physical system is only giving one state to the collection device. A good example of this is the famous Schrödinger's Cat, a thought experiment purposed by Erwin Schrödinger in 1935, where Schrödinger talks about having a cat in a closed box with a vial of poisonous acid with a hammer that will break the vial if any radioactivity is detected (Schrödinger, E., 1935). After a period and if the box stays completely sealed, you cannot one hundred percent know the current state of the cat; it is both alive and dead at the same time, until the box is opened and inspected. Only then would you know the current state of the cat. The next part of quantum physics that is used in quantum computers is quantum entanglement. “Quantum entanglement is when two particles act together in an entangled system. This means that they behave...
