Q-Acceleration

Abstract

Currently only statevector is supported in gpu branch. This proposal adds support unitary and density matrix simulator as master branch does for statevector.

Description

UnitaryMatrix and DensityMatrix extends QubitVector in master branch.
On the other hand, QubitVectorThrust behaves as QubitVector with thrust library that use GPUs if they exist. As UnitaryMatrix and DensityMatrix, UnitaryMatrixThrust and DensityMatrixThrust can be implemented by extending QubitVector.

Required skills:

• C++
• Python (Optional)

References

• Installation Guide
• Note: PR491 may be necessary to enable Thrust with OpenMP.

First step

1. Follow the Installation Guide to setup development environment.
2. Run the following commands

mkdir build/
cd build/
cmake -D AER_THRUST_BACKEND=OMP ..
make
ls Release/

3. Run standalone simulator

• create test.json, and

            ]
        }
    ]
}

• Run the simulator, and confirm statevector_fake_gpu method is used.

$ Release/qasm_simulator test.json | grep statevector
            "method": "statevector_fake_gpu",
