Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

Quantum sensing has become a broad field. It is generally related with the idea of using
quantum resources to boost the performance of a number of practical tasks, including the …

Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

In quantum mechanics, a fundamental law prevents quantum communications to
simultaneously achieve high rates and long distances. This limitation is well known for point …

Quantum metrology holds the promise of an early practical application of quantum
technologies, in which measurements of physical quantities can be made with much greater …

Quantum resource theories have been widely studied to systematically characterize the
nonclassicality of quantum systems. Most resource theories focus on quantum states and …

We show that entangled measurements provide an exponential advantage in sample
complexity for Pauli channel estimation, which is both a fundamental problem and a …

Quantum process tomography is a critical capability for building quantum computers,
enabling quantum networks, and understanding quantum sensors. Like quantum state …
