Active quantum error correction is a central ingredient to achieve robust quantum
processors. In this paper we investigate the potential of quantum machine learning for …

Gottesman-Kitaev-Preskill (GKP) codes encode a qubit in displaced phase-space combs of
a continuous-variable (CV) quantum system and are useful for correcting a variety of high …

We identify the large-N scaling of the metrological quantum gain offered by over-squeezed
spin states that are accessible by one-axis twisting, as a function of the preparation time. We …

In an ensemble of two-level atoms that can be described in terms of a collective spin,
entangled states can be used to enhance the sensitivity of interferometric precision …

We derive general evolution equations describing the ensemble-average quantum
dynamics generated by disordered Hamiltonians. The disorder average affects the …

The most precise measurement of a physical parameter (such as the strength of a field, a
force, or time) is very often obtained by mapping it to a phase that can be determined using …

Understanding the distribution of quantum entanglement over many parties is a fundamental
challenge of quantum physics and is of practical relevance for several applications in the …

Quantum information processing (QIP) based on high-dimensional quantum systems
provides unique advantages and new potentials where high-dimensional quantum …

Pure dephasing and spontaneous emission are two non-unitary processes of atoms or spins
interacting with fluctuating electromagnetic (EM) modes. Collective spontaneous emission …
