Object detection and rangefinding with quantum states using simple detection
Richard J. Murchie, Jonathan D. Pritchard, John Jeffers
In a noisy environment with weak single levels, quantum illumination can outperform classical illumination in determining the presence and range of a target object even in the limi…
Demonstration of quantum-enhanced rangefinding robust against classical jamming
Mateusz P. Mrozowski, Richard J. Murchie, John Jeffers +1
In this paper we demonstrate operation of a quantum-enhanced lidar based on a continuously pumped photon pair source combined with simple detection in regimes with over 5 orders of…
Quantum illumination with multiplexed photodetection
Hao Yang, Nigam Samantaray, John Jeffers
The advantages of using quantum states of light for object detection are often highlighted in schemes that use simultaneous and optimal measurements. Here, we describe a theoretica…
Single-emitter quantum key distribution over 175 km of fiber with optimised finite key rates
Christopher L. Morrison, Roberto G. Pousa, Francesco Graffitti +8
Quantum key distribution with solid-state single-photon emitters is gaining traction due to their rapidly improving performance and compatibility with future quantum network archit…
Measurement disturbance tradeoffs in three-qubit unsupervised quantum classification
Hector Spencer-Wood, Sarah Croke, John Jeffers
We consider measurement disturbance tradeoffs in quantum machine learning protocols which seek to learn about quantum data. We study the simplest example of a binary classification…
Quantum retrodiction: foundations and controversies
Stephen M. Barnett, John Jeffers, David T. Pegg
Prediction is the making of statements, usually probabilistic, about future events based on current information. Retrodiction is the making of statements about past events based on…
