Non-local mass superpositions and optical clock interferometry in atomic ensemble quantum networks
Charles Fromonteil, Denis V. Vasilyev, Torsten V. Zache +5
Quantum networks are emerging as powerful platforms for sensing, communication, and fundamental tests of physics. We propose a programmable quantum sensing network based on entangl…
Optimal Multiparameter Metrology: The Quantum Compass Solution
Denis V. Vasilyev, Athreya Shankar, Raphael Kaubruegger +1
We study optimal quantum sensing of multiple physical parameters using repeated measurements. In this scenario, the Fisher information framework sets the fundamental limits on sens…
Optimal and Variational Multi-Parameter Quantum Metrology and Vector Field Sensing
Raphael Kaubruegger, Athreya Shankar, Denis V. Vasilyev +1
We study multi-parameter sensing of 2D and 3D vector fields within the Bayesian framework for quantum interferometry. We establish a method to determine the optimal quantum…
Optimal metrology with programmable quantum sensors
Christian D. Marciniak, Thomas Feldker, Ivan Pogorelov +7
Quantum sensors are an established technology that has created new opportunities for precision sensing across the breadth of science. Using entanglement for quantum-enhancement wil…
Quantum Variational Optimization of Ramsey Interferometry and Atomic Clocks
Raphael Kaubruegger, Denis V. Vasilyev, Marius Schulte +2
We discuss quantum variational optimization of Ramsey interferometry with ensembles of entangled atoms, and its application to atomic clocks based on a Bayesian approach to pha…
Diagrammatic technique for simulation of large-scale quantum repeater networks with dissipating quantum memories
Viacheslav V. Kuzmin, Denis V. Vasilyev
We present a detailed description of the diagrammatic technique, recently devised in [V. V. Kuzmin et.al., npj Quantum Information 5, 115 (2019)], for semi-analytical description o…
