Quantum Compilation
- Overview
Quantum compilation is the process of transforming quantum algorithms into a sequence of operations that a quantum computer can execute. It involves simplifying quantum circuits and finding the most efficient way to implement them.
Here are some aspects of quantum compilation:
- Circuit complexity: Quantum compilation reduces circuit complexity by repeatedly applying circuit transforms.
- Circuit representation: Quantum compilation finds the most suitable representation for a quantum circuit.
- Gate decomposition: Quantum compilation decomposes quantum gates in terms of the native gates of the quantum device.
- Operation adaptation: Quantum compilation adapts operations to the hardware's topology.
- Operation combination: Quantum compilation combines operations to reduce the circuit depth.
- Circuit depth: Quantum compilation aims to find circuits with the lowest depth.
- Number of gates: Quantum compilation aims to find circuits with the fewest number of gates.
Quantum compilation is important because quantum computers are all about speed. Quantum programs are written in a different way than programs for home computers, so they need different methods to compile.
Quantum compiling is a hybrid between the general-purpose compilers of computers, transforming high-level language to assembly language, and hardware synthesis by hardware description language, where functions are automatically synthesized into customized hardware.
