We study multiparameter sensing of two-dimensional (2D) and three-dimensional (3D) vector fields within the Bayesian framework for SU(2) quantum interferometry. We establish a method to determine the optimal quantum sensor, which establishes the fund

The theoretical understanding of quantum many-body systems often involves properties of energy eigenstates but these are difficult to probe experimentally. Yang et al. propose an experiment that supports preparation and measurement of single eigensta

We discuss quantum variational optimization of Ramsey interferometry with ensembles of N entangled atoms, and its application to atomic clocks based on a Bayesian approach to phase estimation. We identify best input states and generalized measurement

We discuss monitoring the time evolution of an analog quantum simulator via a quantum nondemolition (QND) coupling to an auxiliary “clock” qubit. The QND variable of interest is the “energy” of the quantum many-body system, represented by the

Quantum sensors are an established technology that has created new opportunities for precision sensing across the breadth of science. Using entanglement for quantum-enhancement will allow us to construct the next generation of sensors that can approa

In an ideal quantum measurement, the wave function of a quantum system collapses to an eigenstate of the measured observable, and the corresponding eigenvalue determines the measurement outcome. If the observable commutes with the system Hamiltonian,

We present a detailed description of the diagrammatic technique for a semianalytical description of large-scale quantum repeater networks devised recently by V. V. Kuzmin et al. [npj Quantum Inf. 5, 115 (2019)]. The technique takes into account all e
