QSandbox: The Agile Quantum Software Sandbox

QSandbox is an agile software sandbox specifically designed for Quantum Software research and development. QSandbox agility goes beyond the System Under Development within the sandbox. QSandbox agility is itself modifiable since its high-level modules are varied at will by Quantum Software developers. QSandbox has a series of unique features suitable for agile development. It uses high-level abstraction meaningful modules, instead of low-level quantum gates of conventional simulators. It has instantly synchronized dual views—high-level quantum circuit and density matrix. It has uniform quantum and classical representation, implying the innovative idea of quantum circuits for classical software.
