Why You Can’t Debug a Running Quantum Computer Program

Quantum computing developers face unique debugging challenges, requiring thorough pre-testing as programs cannot be debugged while running. Quantum hardware is expensive and slow due to noise requiring error correction, making simulators essential for testing programs up to 30 qubits, though testing larger programs remains an open question. Quantum computing suits problems with limited input/output but complex computation that would take classical computers prohibitively long to solve.
