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…
Strong coupling and active cooling in a finite temperature hybrid atom-cavity system
Lindsey F. Keary, Jonathan D. Pritchard
For a standard two-level atom coupled to the quantized field of a resonant cavity, finite temperature effects lead to thermal occupation of the cavity modes that obfuscates measure…
Gaussian State-Based Quantum Illumination with Simple Photodetection
Hao Yang, Wojciech Roga, Jonathan D. Pritchard +1
Proofs of the quantum advantage available in imaging or detecting objects under quantum illumination can rely on optimal measurements without specifying what they are. We use the c…
Entanglement of neutral-atom qubits with long ground-Rydberg coherence times
C. J. Picken, R. Legaie, K. McDonnell +1
We report results of a ground-state entanglement protocol for a pair of Cs atoms separated by 6~m, combining the Rydberg blockade mechanism with a two-photon Raman transitions t…
Hybrid Atom--Photon Quantum Gate in a Superconducting Microwave Resonator
J. D. Pritchard, J. A. Isaacs, M. A. Beck +2
We propose a novel hybrid quantum gate between an atom and a microwave photon in a superconducting coplanar waveguide cavity by exploiting the strong resonant microwave coupling be…
