Quantum computers are very different from the ones we use today. They have the potential to solve problems that would take a long time, even impossible, using classical computers. The main difference is that quantum computers work on qubits (quantum bits) instead of bits. A bit can only be in one state at a time: 0 or 1. But qubits can be both 0 and 1 simultaneously, which means they can store more information than binary bits do. This allows them to perform operations faster than conventional computers because they donâ€™t need to go through all possible combinations of states before making a decision. A conventional computer is a computer that uses an electronic circuit to store and process data. The most common type of electronic circuits used in computers are transistors, which are tiny switches that can be on or off at any given time. A transistor is made up of three parts: the base, the emitter and the collector. The base controls whether or not current flows from the source to the collector. The decision of quantum computing is the ability to predict the outcome of a computation.

The most important aspect of this capability is that it can be used to solve problems that are not solvable by classical computers. Quantum computing has many applications in various fields such as medicine, finance, and defense. It also helps in creating new materials for energy production and storage, as well as providing security against cyber attacks. Quantum computers have already been designed with different types of qubits (quantum bits) which can be manipulated to perform specific tasks or calculations at very high speeds. Quantum bits (or qubits) are the smallest unit of information that can be stored in a computer. They are extremely small, but they can perform calculations incredibly quickly. For example, if you have one qubit and you want to find out whether it is 0 or 1, then you need to try every possible combination of 0s and 1s until one matches it. But with two qubits, there are four different possibilities for each bit: 00 , 01 , 10 , 11 . If we had three qubits instead of just two, we could do this calculation much more quickly because each time we tried a new possibility.
