Field-Deployable Hybrid Gravimetry: Projecting Absolute Accuracy Across a Remote 24km Survey via Daily Quantum Calibration
Nathan Shettell, Kai Sheng Lee, Fong En Oon +3
Absolute gravimeters deliver drift-free, high-precision measurements but are typically bulky and difficult to deploy, whereas relative gravimeters are lightweight and mobile but in…
Entropic Efficiency of Bayesian Inference Protocols
Nathan Shettell, Alexia Auffèves
Inference is a versatile tool that underlies scientific discovery, machine learning, and everyday decision-making: it describes how an agent updates a probability distribution as p…
Exclusive Control of Quantum Memory Erasure
Mir Alimuddin, Nathan Shettell, Raja Yehia +2
Erasing memory is a fundamental operational task in quantum information processing, governed by Landauer's principle, which links information loss to thermodynamic work. We introdu…
Geophysical survey based on Hybrid Gravimetry using Relative Measurements and an Atomic Gravimeter as an Absolute Reference
Nathan Shettell, Kai Sheng Lee, Fong En Oon +4
Gravimetry is a versatile metrological approach in geophysics to accurately map subterranean mass and density anomalies. There is a broad diversification regarding the working prin…
Emulating an Atomic Gyroscope with Multiple Accelerometers
Nathan Shettell, Rainer Dumke
The main advantage of an atomic accelerometer when compared to a classical accelerometer is negligible bias drift, allowing for stable long-term measurements, which opens the poten…
Bounding the Minimum Time of a Quantum Measurement
Nathan Shettell, Federico Centrone, Luis Pedro García-Pintos
Measurements take a singular role in quantum theory. While they are often idealized as an instantaneous process, this is in conflict with all other physical processes in nature. In…
Private network parameter estimation with quantum sensors
Nathan Shettell, Majid Hassani, Damian Markham
Networks of quantum sensors are a central application of burgeoning quantum networks. A key question for the use of such networks will be their security, particularly against malic…
Quantum Information Techniques for Quantum Metrology
Nathan Shettell
Quantum metrology is an auspicious discipline of quantum information which is currently witnessing a surge of experimental breakthroughs and theoretical developments. The main goal…
Quantum Metrology with Delegated Tasks
Nathan Shettell, Damian Markham
A quantum metrology scheme can be decomposed into three quantum tasks: state preparation, parameter encoding and measurements. Consequently, it is imperative to have access to the…
Practical Limits of Error Correction for Quantum Metrology
Nathan Shettell, William J. Munro, Damian Markham +1
Noise is the greatest obstacle in quantum metrology that limits it achievable precision and sensitivity. There are many techniques to mitigate the effect of noise, but this can nev…
Cryptographic approach to Quantum Metrology
Nathan Shettell, Elham Kashefi, Damian Markham
We consider a cryptographically motivated framework for quantum metrology in the presence of a malicious adversary. We begin by devising an estimation strategy for a (potentially)…
Graph States as a Resource for Quantum Metrology
Nathan Shettell, Damian Markham
By using highly entangled states, quantum metrology guarantees precision impossible with classical measurements. Unfortunately such states can be very susceptible to noise, and it…
Robust quantum metrology with explicit symmetric states
Yingkai Ouyang, Nathan Shettell, Damian Markham
Quantum metrology is a promising practical use case for quantum technologies, where physical quantities can be measured with unprecedented precision. In lieu of quantum error corre…
