However, with a quantum computer, using 3 qubits, we can represent all 8 of these solutions at the same time. There are debates as to what it means exactly, but here’s the way I think about it. Data in a quantum computer is represented as a series of qubits. Qubits are in some superposition of a 0 state and 1 state. You can think of them as a two-vector of complex numbers such that the sum of the squares of the two complex numbers sums to 1. Often we write out the quantum state of a qubit using "ket" notation, as a|0> + b|1>.
