Benchmarking suite using Catch2

Quantum++ includes a benchmarking suite built using Catch2.

---

Configuring the system

Quantum++ is required to build and run the benchmarks. If it is not installed, the benchmarks can be built by first configuring the main project from this directory using

cmake -S .. -B build/qpp
cmake -B build -DCMAKE_PREFIX_PATH=build/qpp

If Quantum++ is installed on your system, replace the commands above with

cmake -B build

---

Building and running the benchmarks

Once the system is configured, build all benchmarks by executing from this directory

cmake --build build --parallel 8

This will compile all benchmark executables into ./build/benchmarks. To run a specific benchmark, e.g., qft_bench, execute

./build/benchmarks/qft_bench

For help and additional options, run any benchmark with the --help flag.

Note: Quantum++ CMake configuration options do not propagate to the benchmarks. They must be defined independently if they are needed.
