Robust certification of high-dimensional quantum devices

Javier Fernández, Albert Rico, David Viedma +6

Certifying quantum behavior from classically accessible data is essential for secure communication and scalable quantum technologies. While powerful certification methods such as B…

Entangling a quantum system to disentangle its parts

Albert Rico, Jofre Abellanet-Vidal, Naga Bhavya Teja Kothakonda +2

In quantum systems, correlations are subject to monogamy relations between the whole and its parts. In particular, entanglement between two sets of particles constrains the entangl…

Bounding the entanglement of a state from its spectrum

Jofre Abellanet-Vidal, Guillem Müller-Rigat, Albert Rico +1

We introduce a framework to upper bound the entanglement content of a bipartite quantum state from its spectrum alone. Using linear maps and their inverses, we derive rigorous cons…

Absolutely maximally entangled pure states of multipartite quantum systems

Grzegorz Rajchel-Mieldzioć, Rafał Bistroń, Albert Rico +2

Absolutely maximally entangled (AME) pure states of a system composed of parties are distinguished by the property that for any splitting at least one partial trace is maximall…

Channel nonlocality under decoherence

Albert Rico, Moisés Bermejo Morán, Fereshte Shahbeigi +1

The implementation of realistic quantum devices requires a solid understanding of the nonlocal resources present in quantum channels, and the effects of decoherence on them. Here w…

Certifying nonlocal properties of noisy quantum operations

Albert Rico, Moisés Bermejo Morán, Fereshte Shahbeigi +1

Certifying quantum properties from the probability distributions they induce is an important task for several purposes. While this framework has been largely explored and used for…

Discrete dynamics in the set of quantum measurements

Albert Rico, Karol Życzkowski

A quantum measurement, often referred to as positive operator-valued measurement (POVM), is a set of positive operators summing to identity, $\sum_jP_j=\mathbb{1}…

Entanglement detection with trace polynomials

Albert Rico, Felix Huber

We provide a systematic method for nonlinear entanglement detection based on trace polynomial inequalities. In particular, this allows to employ multi-partite witnesses for the det…
