Hello. Our current computers use bits, so they use the binary numeral system. But I heard that the future quantum computers will use qubits instead of simple bits. Since in the word "qubit" there is the word "bi" I first thought that this meant that quantum computers would use binary (base 2). But then I heard that qubits had three possible states: 0, 1, or a superposition of 0 and 1. So I then thought that this must mean that they will use ternary (base 3). But then I saw that one qubit can hold as much information as two bits. So I thought that this maybe mean that they will use quaternary (base 4). So which numeral system will the future quantum computers use: binary, ternary or quaternary? Thanks in advance for your answers.
