Hi I was just wondering if someone could explain superposition in QM? Is it to get the probability of finding a particle in a certain state of a wavefunction that would have both positive and negative probabilities?

The concept of superposition in quantum mechanics refers to the principle that a physical system can exist in multiple states simultaneously. This means that a particle can be in more than one location or have more than one energy state at the same time.
In classical mechanics, a physical system can only exist in one state at a time. However, in quantum mechanics, a system can exist in a superposition of states, meaning it can have multiple properties at once.
Observation in quantum mechanics plays a crucial role in determining the state of a system. When a measurement is made, the system collapses into one of its possible states, and the other potential states are no longer present.
An example of superposition in everyday life is the double-slit experiment, where a particle can pass through both slits simultaneously, creating an interference pattern. This demonstrates the concept of a particle existing in multiple positions at once.
Superposition is a fundamental principle of quantum mechanics that allows for the potential of exponentially more computational power in quantum computers. Quantum bits, or qubits, can exist in a superposition of 0 and 1, allowing for the manipulation of multiple states at once and solving complex problems much faster than classical computers.
