[[Why Quantum]] You can represent classical bits as 2D vectors. Quantum operators running on a simulator are operated by matrix operations. By doing matrix operations we can simulate nature and quantum. ### Operations on a Classical Bit of Info: 1. Identity 2. Negation 3. Const 0 4. Const 1 Irreversible, if you know the result, you don't know the input. ### Quantum Computers use only reversible operations Tensor Products are used Order of conducting the Tensor Product is important (it's not commutative, not associative) ![[Pasted image 20220127085812.png]] Classical bit vectors so far are just special cases of qubit vectors
