Unitary circuits subject to repeated projective measurements can undergo an entanglement
phase transition (EPT) as a function of the measurement rate. This transition is generally …

Quantum sensors outperform their classical counterparts in their estimation precision, given
the same amount of resources. So far, quantum-enhanced sensitivity has been achieved by …

The conventional formulation of quantum sensing is based on the assumption that the probe
is reset to its initial state after each measurement. In a very distinct approach, one can also …

The time evolution of spin chains has been extensively studied for transferring quantum
states between different registers of a quantum computer. Nonetheless, in most of these …

Measurement is one of the key concepts which discriminates classical and quantum physics.
Unlike classical systems, a measurement on a quantum system typically alters it drastically …

In this work, we study optimal transfer of quantum states via spin chains. We develop the
protocol for structural restoring of multi-quantum coherence matrices of multi-qubit quantum …

Suppose a quantum system starts to evolve under a Hamiltonian from some initial state.
When, for the first time, will an observable attain a preassigned value? To answer this …

The main power of quantum sensors is achieved when the probe is composed of several
particles. In this situation, quantum features such as entanglement contribute in enhancing …

Measuring the temperature of a quantum system is an essential task in almost all aspects of
quantum technologies. Theoretically, an optimal strategy for thermometry often requires …

In this work, we study transfer of coherence matrices along spin-1/2 chains of various length.
Unlike higher order coherence matrices, zero-order coherence matrix can be perfectly …
