# What is quantum superposition and quantum entanglement (no wikipedia answers pls)?

quantum superposition is an expression that defines an events final outcome as the combination of all possible outcomes. take schrodinger’s cat, there is a cat in a box and you know that the cat is there but you do not know if it is alive or dead; there is a poison gas that kills the cat the instant that the box is opened, so when you open the box all you will see is a dead cat; however, while the box is closed, the cat is neither alive nor dead, it is both. that is quantum superposition, the event is defined by all the possible outcomes put together quantum entanglement is the state of sub-atomic particles to come in pairs that complement each other so that if you know the state of one of the particles in the pair then you know the state of the other without actually observing the state of the other particle. say a system of particles decays into two electrons, where one has an up spin and the other has a down spin; if you measure the spin of one of the electrons to be up, then you kn
