Web(If there are 64 qubits and only 22 CNOTs, not every qubit can be entangled with every other). The memory consumption can also depend on the simulation algorithm used. The most common is to store the quantum state as a vector of complex single precision floating point numbers and transform them based off the matrix form of the gate. WebDec 27, 2024 · Representing a qubit. While a bit, or binary digit, can have a value either 0 0 or 1 1, a qubit can have a value that is either 0 0, 1 1 or a quantum superposition of 0 0 and 1 1. The state of a single qubit can be described by a two-dimensional column vector of unit norm, that is, the magnitude squared of its entries must sum to 1 1.
