We connect two recent advances in the stochastic analysis of nonequilibrium systems: the
(loose) uncertainty principle for the currents, which states that statistical errors are bounded …

We analyze the effects of quantum correlations, such as entanglement and discord, on the
efficiency of phase estimation by studying four quantum circuits that can be readily …

Simulating quantum features of quantum systems is an important path to approaching
quantum technologies and understanding the physical world. This paper inspects the …

We investigate the performance of quantum Fisher information (QFI) under the Unruh-
Hawking effect, where one of the observers (eg, Rob) is uniformly accelerated with respect …

Quantum-enhanced metrology infers an unknown quantity with accuracy beyond the
standard quantum limit (SQL). Feedback-based metrological techniques are promising for …

In this paper we analyze the problem of “apparent” superluminal signalling and
retrocausation that can appear for particle detector models when considering noncompactly …

The inequality, with L being the grand orbital quantum number, and its conjugate relation for

Entanglement in fermion many-body systems is studied using a generalized definition of
separability based on partitions of the set of observables, rather than on particle tensor …

We consider a cryptographically motivated framework for quantum metrology in the
presence of a malicious adversary. We begin by devising an estimation strategy for a …

We devise powerful algorithms based on differential evolution for adaptive many-particle
quantum metrology. Our new approach delivers adaptive quantum metrology policies for …
