This review aims at gathering the most relevant quantum multi-parameter estimation
methods that go beyond the direct use of the quantum Fisher information concept. We …

Large-scale quantum effects have always played an important role in the foundations of
quantum theory. With recent experimental progress and the aspiration for quantum …

We study the problem of learning the Hamiltonian of a many-body quantum system from
experimental data. We show that the rate of learning depends on the amount of control …

We consider a general model of unitary parameter estimation in the presence of Markovian
noise, where the parameter to be estimated is associated with the Hamiltonian part of the …

Quantum sensing is one of the arenas that exemplifies the superiority of quantum
technologies over their classical counterparts. Such superiority, however, can be diminished …

The Heisenberg limit [(HL), with estimation error scales as 1/n] and the standard quantum
limit (SQL,∝ 1/n) are two fundamental limits in estimating an unknown parameter in n copies …
