| "ProjectQ allows a user to write a quantum program in a high-level language. For example, one can apply quantum operations on n-qubits, e.g., `QFT`, and the compiler will decompose this operations into two qubit and single qubit gates. See the [compiler_tutorial](https://github.com/ProjectQ-Framework/ProjectQ/tree/develop/examples) for an introduction.\n", | ||

| "After decomposing a quantum program into two qubit and single qubit gates which a quantum computer supports, we have to take the physical layout of these qubits into account. Two qubit gates are only possible if the qubits are next to each other. For example the qubits could be arranged in a linear chain or a two dimensional grid and only nearest neighbour qubits can perform a two qubit gate. ProjectQ uses **mappers** which move the positions of the qubits close to each other using `Swap` operations in order that we can execute a two qubit gate.\n", |
