Networked quantum sensing
T. J. Proctor, P. A. Knott, J. A. Dunningham
We introduce a general model for a network of quantum sensors, and we use this model to consider the question: when do correlations (quantum or classical) between quantum sensors e…
Correspondence: Enhancing a phase measurement by sequentially probing a solid state system
P. A. Knott, W. J. Munro, J. A. Dunningham
In a recent paper, Liu et al. [Nat. Commun. 6:6726 (2015)] claim to perform the first room temperature entanglement-enhanced phase measurement in a solid-state system. We argue her…
Practical quantum metrology with large precision gains in the low photon number regime
P. A. Knott, T. J. Proctor, A. J. Hayes +2
Quantum metrology exploits quantum correlations to make precise measurements with limited particle numbers. By utilizing inter- and intra- mode correlations in an optical interfero…
Attaining sub-classical metrology in lossy systems with entangled coherent states
P. A. Knott, W. J. Munro, J. A. Dunningham
Quantum mechanics allows entanglement enhanced measurements to be performed, but loss remains an obstacle in constructing realistic quantum metrology schemes. However, recent work…
Quantum metrology with rotating matter waves in different geometries
J. A. Dunningham, J. J. Cooper, D. W. Hallwood
A promising practical application of entanglement is metrology, where quantum states can be used to make measurements beyond the shot noise limit. Here we consider how metrology sc…
Robust quantum enhanced phase estimation in a multimode interferometer
J. J. Cooper, D. W. Hallwood, J. A. Dunningham +1
By exploiting the correlation properties of ultracold atoms in a multi-mode interferometer, we show how quantum enhanced measurement precision can be achieved with strong robustnes…
