Classical shadows enable us to learn many properties of a quantum state ρ with very few measurements. However, near-term and early fault-tolerant quantum computers will only be able to prepare noisy quantum states ρ and it is thus a considerable ch

We investigate the physics of photonic band structures of the moiré patterns that emerged when overlapping two unidimensional photonic crystal slabs with mismatched periods. The band structure of our system is a result of the interplay between intra

The quantum marginal problem interrogates the existence of a global pure quantum state with some given marginals. Here, the authors reformulate it as an optimisation problem, and specifically as the existence of a two-party separable state with addit

Many problems in information theory can be reduced to optimizations over matrices, where the rank of the matrices is constrained. We establish a link between rank-constrained optimization and the theory of quantum entanglement. More precisely, we pro

From the literature, the managements for nephropulmonary fistula were variable. We would like to present our case and review the literature for the best method of care.The common features were 1) infected kidney; 2) ipsilateral lower lobe pneumonia o

Quantum steering is a recently defined form of quantum correlation which lies at the heart of quantum mechanics. In contrast to other types of quantum correlations, quantum steering is inherently asymmetric, which implies that it could manifest in on

Temperature estimation of interacting quantum many-body systems is both a challenging task and topic of interest in quantum metrology, given that critical behavior at phase transitions can boost the metrological sensitivity. Here we study non-invasiv

Entanglement in bipartite systems has been applied for the generation of secure random numbers, which are playing an important role in cryptography or scientific numerical simulations. Here, we propose to use multipartite entanglement distributed bet

Quantum theory allows for different classes of correlations, such as entanglement, steerability or Bell-nonlocality. Experimental demonstrations of the preparation of quantum states within specific classes and their subsequent interconversion have be
