Contractivity of the Hilbert--Schmidt Speed and Unitality--Divisibility-Based Witnesses in Finite-Dimensional Quantum Dynamics

Hossein Rangani Jahromi

We investigate the Hilbert--Schmidt speed as a witness of non-Markovianity in finite-dimensional quantum dynamics. For a differentiable one-parameter family of quantum states, the…

Relativistic quantum thermometry through a moving sensor

Hossein Rangani Jahromi, Samira Ebrahimi Asl Mamaghani, Rosario Lo Franco

Using a two-level moving probe, we address the temperature estimation of a static thermal bath modeled by a massless scalar field prepared in a thermal state. Different couplings o…

Memory effects in high-dimensional systems faithfully identified by Hilbert-Schmidt speed-based witness

Kobra Mahdavipour, Mahshid Khazaei Shadfar, Hossein Rangani Jahromi +2

A witness of non-Markovianity based on the Hilbert-Schmidt speed (HSS), a special type of quantum statistical speed, has been recently introduced for low-dimensional quantum system…

Remote sensing and faithful quantum teleportation through non-localized qubits

Hossein Rangani Jahromi

One of the most important applications of quantum physics is quantum teleportation, the possibility to transfer quantum states over arbitrary distances. In this paper, we address t…

Searching for exceptional points and inspecting non-contractivity of trace distance in (anti-)symmetric systems

Hossein Rangani Jahromi, Rosario Lo Franco

Non-Hermitian systems with parity-time () symmetry and anti- symmetry give rise to exceptional points (EPs) with intriguing properties related to, e.g.,…

Hilbert-Schmidt speed as an efficient tool in quantum metrology

Hossein Rangani Jahromi, Rosario Lo Franco

We investigate how the Hilbert-Schmidt speed (HSS), a special type of quantum statistical speed, can be exploited as a powerful and easily computable tool for quantum phase estimat…

Witnessing non-Markovian effects of quantum processes through Hilbert-Schmidt speed

Hossein Rangani Jahromi, Kobra Mahdavipour, Mahshid Khazaei Shadfar +1

Non-Markovian effects can speed up the dynamics of quantum systems while the limits of the evolution time can be derived by quantifiers of quantum statistical speed. We introduce a…
