QCE20 Workshop on
Practical Quantum Sensing (PQS) from a Photonic and Atomic Physics Perspective




Quantum sensing has recently moved from the laboratory into a more applied and practical domain. In particular, sensors that minimize classical noise sources to the point where photonic statistics and back action dominate the measurement signal to noise are becoming more common. This workshop will outline the methods, techniques, and fundamental physics behind quantum sensing from a photonics and AMO physics point of view, with special attention paid to the path to building quantum sensors that genuinely outperform classical devices from a signal to noise and resource cost point of view.

Call for Papers

The workshop consists of three sessions. Submissions are sought for the following research topics.

  • Building the best possible sensor, first

Often, in order to build a useful quantum sensor, the best possible classical sensor configuration must be built first.  Only then can its performance be surpassed through the use of quantum effects. Key aspects to discuss include minimizing classical noise sources in sensors – reaching the standard quantum limit – and minimizing loss in all sensor configurations.

  • Optimization of sensing modalities and data analysis

Combining the physics of quantum sensing with powerful post processing techniques brings great potential. Machine learning can be used to tune optimal design of a sensing apparatus, while similar techniques can be used to uncover patterns in the data and effectively discover highly efficient demodulation formats previously invisible to the end user. Quantum computing can also play a role in improving the efficiency of quantum sensors through the application of quantum optimization in post processing.

  • Harnessing quantum effects in quantum sensors

Squeezed states of light, atomic systems, and microwave fields can all serve to provide quantum-enhanced signal transduction pathways. Additional discrete quantum effects such as energy-time entanglement will also play a large role in improving sensors in the near term. Frequency combs can be used to reduce timing uncertainty in ultrafast dynamics measurements to below the Fourier limit. This session seeks input on a wide range of quantum sensing modalities, from atomic, molecular, and optical devices to superconducting circuits.
