Description

Problem Statement

Currently, only the analog simulation has a statevector backend through the MCWF setting.

Proposed Solution

I would like to add a statevector based circuit simulator particularly for smaller circuits and to give an entry point for GPU acceleration. This should be done in a proper, scalable way such as by tensorizing the statevector and only applying gates to the required indices, rather than making large matrices etc.

Research direction

Start by locating and reading the existing analog statevector backend implemented through the MCWF setting. Define the circuit simulator’s scope and completion criteria before implementation: it should support smaller circuits, apply gates through a scalable tensorized statevector approach, and provide an entry point for GPU acceleration.
