Frequentist Parameter Estimation with Supervised Learning
Samuel P. Nolan, Luca Pezzè, Augusto Smerzi
Recently there has been a great deal of interest surrounding the calibration of quantum sensors using machine learning techniques. In this work, we explore the use of regression to…
A machine learning approach to Bayesian parameter estimation
Samuel P. Nolan, Augusto Smerzi, Luca Pezzè
Bayesian estimation is a powerful theoretical paradigm for the operation of quantum sensors. However, the Bayesian method for statistical inference generally suffers from demanding…
High Precision, Quantum-Enhanced Gravimetry with a Bose-Einstein Condensate
Stuart S. Szigeti, Samuel P. Nolan, John D. Close +1
We show that the inherently large interatomic interactions of a Bose-Einstein condensate (BEC) can enhance the sensitivity of a high precision cold-atom gravimeter beyond the shot-…
Generating Macroscopic Superpositions with Interacting Bose-Einstein Condensates: Multi-Mode Speed-Ups and Speed Limits
Samuel P. Nolan, Simon A. Haine
We theoretically investigate the effect of multi-mode dynamics on the creation of macroscopic superposition states (spin-cat states) in Bose-Einstein condensates via one-axis twist…
Robustifying Twist-and-Turn Entanglement with Interaction-Based Readout
Safoura S. Mirkhalaf, Samuel P. Nolan, Simon A. Haine
The use of multi-particle entangled states has the potential to drastically increase the sensitivity of atom interferometers and atomic clocks. The Twist-and-Turn (TNT) Hamiltonian…
Optimal and Robust Quantum Metrology Using Interaction-Based Readouts
Samuel P. Nolan, Stuart S. Szigeti, Simon A. Haine
Useful quantum metrology requires nonclassical states with a high particle number and (close to) the optimal exploitation of the state's quantum correlations. Unfortunately, the si…
Quantum Fisher Information as a Predictor of Decoherence in the Preparation of Spin-Cat States for Quantum Metrology
Samuel P. Nolan, Simon A. Haine
In its simplest form, decoherence occurs when a quantum state is entangled with a second state, but the results of measurements made on the second state are not accessible. As the…
Quantum Enhanced Measurement of Rotations with a Spin-1 Bose-Einstein Condensate in a Ring Trap
Samuel P. Nolan, Jacopo Sabbatini, Michael W. J. Bromley +2
We present a model of a spin-squeezed rotation sensor utilising the Sagnac effect in a spin-1 Bose-Einstein condensate in a ring trap. The two input states for the interferometer a…
