Researchers reach milestone in quantum standardization

Researchers at the University of Waterloo have developed a method that could pave the way to establishing universal standards for measuring the performance of quantum computers.

The new method, called cycle benchmarking, allows researchers to assess the potential of scalability and to compare one quantum platform against another.

“This finding could go a long way toward establishing standards for performance and strengthen the effort to build a large-scale, practical quantum ,” said Joel Wallman, an assistant professor at Waterloo’s Faculty of Mathematics and Institute for Quantum Computing. “A consistent method for characterizing and correcting the errors in provides standardization for the way a is assessed, allowing progress in different architectures to be fairly compared.”

Computer Scientists Expand the Frontier of Verifiable Knowledge

The universe of problems that a computer can check has grown. The researchers’ secret ingredient? Quantum entanglement.

By interrogating entangled quantum computers, a person can verify the answers to enormously complicated problems.

Imagine someone came along and told you that they had an oracle, and that this oracle could reveal the deep secrets of the universe. While you might be intrigued, you’d have a hard time trusting it. You’d want some way to verify that what the oracle told you was true.

This is the crux of one of the central problems in computer science. Some problems are too hard to solve in any reasonable amount of time. But their solutions are easy to check. Given that, computer scientists want to know: How complicated can a problem be while still having a solution that can be verified?

Turns out, the answer is: Almost unimaginably complicated.

Computação quântica é a nova maratona da civilização

Você acorda cedo. A persiana do quarto percebe automaticamente que se levantou, permite a entrada da luz solar, informa temperatura e previsão climática, ajudando-o a escolher a roupa do dia. Você vai até a cozinha, onde seu café da manhã já está prontinho te esperando.

Seu carro elétrico autônomo escolhe o caminho mais eficiente e o leva até o aeroporto enquanto você discute com o celular detalhes da apresentação que fará em Londres no final da tarde. Como seu voo será em um avião supersônico, é possível chegar em qualquer lugar do mundo em três horas.

Toshiba says its device tests for 13 cancer types with 99% accuracy from a single drop of blood

Toshiba Corp. has developed technology to detect 13 types of cancer from a single drop of blood with 99 percent accuracy, the company announced Monday.

Toshiba developed the diagnosis method together with the National Cancer Center Research Institute and Tokyo Medical University, and hopes to commercialize it in “several years” after starting a trial next year.

The method could be used to treat cancer in its early stage, it said. Leer Más

Criatividade será 3ª habilidade mais importante para o mercado de trabalho futuro

Em 2015, a criatividade era considerada como a 10ª habilidade mais importante para o mercado de trabalho. Desde então, ela galgou posições e hoje é considerada o terceiro skill principal para quem busca se tornar um profissional bem-sucedido.

Esta mudança foi um dos temas abordados durante o Fórum Econômico de Davos de 2018. Durante o encontro global, ficou claro que as artes se tornaram hoje parte fundamental da chamada quarta revolução industrial. A criatividade foi indicada como uma das três principais habilidades necessárias para o profissional do futuro, ao lado da capacidade de resolver problemas complexos e do pensamento crítico.

Scientists Used IBM’s Quantum Computer to Reverse Time, Possibly Breaking a Law of Physics


The universe is getting messy. Like a glass shattering to pieces or a single wave crashing onto the shore, the universe’s messiness can only move in one direction – toward more chaos and disorder. But scientists think that, at least for a single electron or the simplest quantum computer, they may be able to turn back time, and restore order to chaos. This doesn’t mean we’ll be visiting with dinosaurs or Napoleon any time soon, but for physicists, the idea that time can run backward at all is still a pretty big deal.

Normally, the universe’s trend toward disorder is a fundamental law: the second law of thermodynamics.
