Quantum computing goes beyond hardware, according to Dr. Muhammad Usman, the head of quantum software at Data61, a division of Australia’s CSIRO. Usman emphasizes the significance of quantum algorithms and software in addition to hardware development.
Data61, established in 2016, boasts a diverse team of over 1,000 staff, including 300 PhD students from various countries. Usman, who completed his PhD in quantum computing at Purdue University, is leading efforts to advance quantum algorithms and software at CSIRO.
Despite the lack of operational large-scale quantum computers, interest in quantum algorithms is high. Usman’s team is collaborating with the Queensland government to develop quantum algorithms for optimizing traffic and athlete movement at the 2032 Brisbane Olympics.
While quantum computers have made significant progress in recent years, with companies like IBM and Google advancing the technology, current quantum processors still face challenges such as errors. Usman’s team is actively working on error correction schemes to enhance both hardware and software development.
Quantum computing operates on the principles of quantum mechanics, offering qubits that can represent 0, 1, or a combination of both. This unique property, known as superposition, allows for a vast computational space that classical systems lack.

Usman’s team is engaged in various quantum software projects, including enhancing artificial intelligence, optimizing traffic flow, and supporting climate science research. Quantum artificial intelligence, with its entangled neural networks, offers robustness and security advantages over classical systems.
Despite the current absence of large-scale quantum computers, Usman stresses the importance of developing quantum software and algorithms in parallel with hardware advancements. He anticipates the emergence of quantum computers capable of tasks beyond classical computing in the near future.
Usman highlights the necessity of quantum software to unlock the full potential of quantum processors. Just as hardware alone is insufficient without an operating system, quantum computers require sophisticated algorithms and software to perform meaningful tasks.
Looking ahead, Usman remains optimistic about the future of quantum computing, emphasizing the need for continued innovation in both hardware and software development. As the field progresses, the integration of advanced algorithms will be crucial for harnessing the power of quantum processors.
