We describe the most general form of the Alicki–Fannes–Winter method for obtaining
uniform continuity bounds for characteristics of composite quantum systems and consider …

We study how useful random states are for quantum metrology, ie, whether they surpass the
classical limits imposed on precision in the canonical phase sensing scenario. First, we …

We present several inequalities related to the Robertson-Schrödinger uncertainty relation. In
all these inequalities, we consider a decomposition of the density matrix into a mixture of …

We address the discontinuities of the quantum Fisher information (QFI) that may arise when
the parameter of interest takes values that change the rank of the quantum statistical model …

This work compares the performance of single-and two-qubit probes for estimating several
phase rotations simultaneously under the action of different noisy channels. We compute the …

We analyze the problem of estimating a scalar parameter g that controls the Hamiltonian of a
quantum system subject to Markovian noise. Specifically, we place bounds on the growth …

In this paper, we address the problem of quantum teleportation in single and two-qubit
scenarios based on the Heisenberg XYZ two-qubit chain model under the influence of …

We address multiparameter quantum estimation for one-dimensional discrete-time quantum
walks and its applications to quantum metrology. We use the quantum walker as a probe for …

We treat privacy in a network of quantum sensors where accessible information is limited to
specific functions of the network parameters, and all other information remains private. We …

Detection of very weak forces and precise measurement of time are two of the many
applications of quantum metrology to science and technology. To sense an unknown …
