Quantum technologies present a transformative frontier for oncology, promising significant advancements in diagnostics, treatment precision, and drug discovery. The clinical realization of this potential is fundamentally reliant on mastering quantum control-the precise manipulation of quantum systems. This perspective details how quantum control is integral across emerging quantum oncology applications, potentially enhancing quantum imaging and quantum sensing by boosting signal sensitivity, improving clarity (e.g., fivefold Signal to Noise Ratio increase), and enabling subcellular visualization. In quantum omics, it could facilitate precise single-cell analysis and drive quantum machine learning for advanced biomarker discovery and validation. For treatment, such precise manipulation could optimise radiation targeting in quantum radiotherapy, could enable real-time tracking for precise quantum surgery, guide targeted delivery in quantum chemotherapy via controlled nanoparticle release, and could enhance the design and precision of quantum immunotherapy and personalised therapies. Overcoming challenges such as coherence and scalability is necessary, but advancements in quantum control are paramount for translating these capabilities into clinical benefits, ultimately improving cancer diagnosis and patient outcomes.
