Quantum sensing is the use of quantum systems and quantum effects (superposition, entanglement, quantum interference) to measure physical quantities such as magnetic fields, electric fields, gravity, temperature, rotation, and time with sensitivity or resolution beyond classical limits.
Why it matters. Quantum sensing is arguably the most commercially mature branch of quantum technology. Atomic clocks (used in GPS satellites and telecommunications) are already deployed at scale. Quantum magnetometers, gravimeters, and accelerometers are entering the market for applications in navigation, medical imaging, geological surveying, and defense. Unlike quantum computing, which requires error correction to reach its full potential, many quantum sensing applications can deliver value with today's technology. The control requirements for quantum sensors (precise pulse timing, low noise, fast readout, and high synchronisation) overlap significantly with the requirements for quantum computing.
How it connects. The Qblox Cluster's control capabilities are directly applicable to quantum sensing experiments. Precise pulse sequencing (Q1 Sequence Processor), high-resolution time-tagging (QTM), low-noise signal generation (QCM, QCM-RF II), and deterministic synchronization (SYNQ) provide the tools needed for high-performance quantum sensing across multiple modalities.
