Fault-tolerant noise guessing decoding of quantum random codes

This work addresses the open question of implementing fault-tolerant QRLCs with feasible computational overhead. We present a new decoder for quantum random linear codes (QRLCs) capable of dealing with imperfect decoding operations. A first approach, introduced by Cruz et al., only considered channel errors, and perfect gates at the decoder. Here, we analyze the fault-tolerant characteristics of QRLCs with a ne...

Efficient entanglement purification based on noise guessing decoding

In this paper, we propose a novel bipartite entanglement purification protocol built upon hashing and upon the guessing random additive noise decoding (GRAND) approach recently devised for classical error correction codes. Our protocol offers substantial advantages over existing hashing protocols, requiring fewer qubits for purification, achieving higher fidelities, and delivering better yields with reduced com...

Migration in the ABCD assessment tool after community-based pulmonary rehabilit...

Objectives: The ABCD assessment tool (ABCD) proposed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) is often used to guide treatment in chronic obstructive pulmonary disease (COPD). However, treatment remains focused on pulmonary pharmacology, despite being known that this will have minimal effects on meaningful aspects of people’s daily life such as symptoms. Pulmonary rehabilitation (PR)...

The feasibility of using gas mixture to stun seabream (Sparus aurata) before sl...

Current European Union regulation explicitly states that farmed fish should be spared any avoidable pain, distress or suffering at the time of slaughter. It has been shown that fish suffer when they are killed in an ice slurry, the most common method of killing farmed fish in the Mediterranean. Thus, it is necessary to find a method of slaughtering Mediterranean fish that is, (1) efficient in inducing unconscio...

Managing the herdbook of an endangered Portuguese swine population: the Malhado...

Malhado de Alcobaça breed is the 3rd Portuguese native swine breed and represents a population from the centre west of Portugal and was officially recognised in 2003. The herdbook has information of more than 11,000 animals (1985-2020) and the last animals have more than 10 known generations on their pedigree. It´s a very endangered breed with only 211 breeding sows, 12 boars and 9 active breeders. Since 2014 a...

Temperature distribution of a Fast-Field Cycling Nuclear Magnetic Resonance rel...

The temperature distribution of a Fast Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) electromagnet plays an important role in the operation of this type of apparatus. The designed electromagnet presents a reduced volume and is iron and copper based, fulfilling the technical requirements for the magnetic field. With this solution, it is possible to increase the overall performance in comparison with forme...

Desenvolvimento como liberdade:uma aplicação dos conceitos de Amartya Sen à edu...

Desenvolver uma sociedade significa transformá-la. Com base em críticas a modelos prescritivos tradicionais de desenvolvimento que subestimavam sua dimensão humana Amartya Sen, em desenvolvimento como liberdade (2000), discute o desenvolvimento integrando os aspectos econômicos, sociais e políticos. De acordo com os conceitos de Sen, o desenvolvimento é um processo de expansão das liberdades reais que as pessoa...

Fast-Field Cycling Nuclear Magnetic Resonance relaxometer's electromagnet with ...

In this article a Fast Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) electromagnet with low power consumption (less than 200 W), high field homogeneity and reduced volume is projected and described. The electromagnet is iron and copper based, possessing a high permeability and allowing for good magnetic field homogeneity in the operating range of 0 to 0.33 T. With this solution, it is possible to increas...

Measuring the efficiency of an industrial condition monitoring service

The mode how industrial physical assets are maintained is very importante to assure high equipment availability. I tis importante to find a metric or a key indicator that will point out the effectiveness of such function. Once condition based maintenance is widely assumed to be one of the most importante maintenance strategies, it is fundamental to observe how assets are being monitored. The purpose of this pap...
