Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

The laws of quantum mechanics allow to perform measurements whose precision
supersedes results predicted by classical parameter estimation theory. That is, the precision …

A method for the systematic construction of few-body damped harmonic oscillator networks
accurately reproducing the effect of general bosonic environments in open quantum systems …

We study quantum frequency estimation for N qubits subjected to independent Markovian
noise, via strategies based on time-continuous monitoring of the environment. Both physical …

We show how to recover complete positivity (and hence positivity) of the Redfield equation
via a coarse-grained averaging technique. We derive general bounds for the coarse …

Quantum metrology protocols are typically designed around the assumption that we have an
abundance of measurement data, but recent practical applications are increasingly driving …

Optical sensors based on quantum light need to work even in the presence of imperfections.
Here we discuss how to address the presence of noise by measuring multiple parameters at …

The quantum speed limit (QSL) sets a bound on the minimum time required for a quantum
system to evolve between two states. For open quantum systems this quantity depends on …

We present a flexible scheme to realize non-Markovian dynamics of an electronic spin qubit,
using a nitrogen-vacancy center in diamond where the inherent nitrogen spin serves as a …

We address the structure of the Liouvillian superoperator for a broad class of bosonic and
fermionic Markovian open systems interacting with stationary environments. We show that …
