The Current Status of The Quantum Software Stack

Programming a quantum computer involves several distinct approaches, from the common gate-based circuit model to specialized analog systems and hybrid workflows that combine quantum and classical power. Developers can write code using various tools, including low-level instruction sets for precise control, popular Python frameworks like Qiskit, and new quantum-specific languages such as Q#. These quantum programs are executed either on classical simulators for development or on real hardware made accessible through cloud platforms like IBM Quantum and AWS Braket. However, the field is still in its early stages, with major challenges remaining in creating effective tools for debugging and testing, which are fundamentally different from their classical counterparts.
