QVM

The Quantum Virtual Machine (QVM) is a classical simulator for Quil programs. It provides a high-performance, featureful implementation of the Quantum Abstract Machine (QAM), designed to model various characteristics of real quantum hardware.

The QVM is available as a library for integration into other projects and as a standalone application. The application can be run as a command-line binary or as a server, enabling remote access and integration with client libraries like the Python SDK.

Key features and capabilities include:

• Executing Quil programs.
• Inspecting quantum state amplitudes.
• Simulating quantum measurements and state collapse.
• High performance through optimized implementations, including optional assembly intrinsics (e.g., AVX2).
• Flexible memory management options for simulating larger numbers of qubits.
• Docker images for easy deployment and CI integration.

It serves as a crucial tool for developing and testing Quil programs before deployment on quantum hardware.
