A controversial study published in 2018 by a team at Microsoft, in which researchers claimed to have found evidence that a subatomic particle could support the development of quantum computers more powerfully than conventional ones, was removed by the journal Nature.
The vehicle announced the event through a withdrawal note and the authors of the article apologized for the ‘insufficient scientific rigor’ presented, in addition to listing errors made, such as ‘unnecessary corrections’ of data without due clarity and incorrect labeling of data. a graph, a fact that made it misleading.
In any case, the technology giant confirms that it remains confident in its wider efforts to deliver results in the area, which is seen as a potentially revolutionary leap for humanity.
For example, if on traditional machines, the information unit (bit) can have a value of 1 or 0, the quantum equivalent can present both at the same time, allowing multiple calculations to be performed simultaneously.
To arrive at this scenario, specialists are committed to the construction of functional and commercially competitive devices – and the challenge doesn’t seem as close as some claims suggest.
Not everything is what it looks like
IBM, Google, Intel, D-Wave and IonQ are some of the companies that want to overcome the obstacles of quantum computing, and Microsoft, among them, decided to bet on the creation of qubits with properties of the Majorana quasi-particle, which is was first presented in the decade. from 1930 by the Italian physicist Ettore Majorana and found by Dutch scientists in 2012.
“It’s a much more exotic challenge than what’s happening with other approaches to quantum computing,” Charlie Marcus told BBC News, one of the project’s researchers, in 2018.
According to the company, the specificity of the element, neutral and at the same time its own anti-particle, would make the units less prone to error. However, subsequent analyzes were not favorable for the alleged performance.
Since its founding in 1869, the journal Nature has removed only 79 publications from its platform, eight of which were not until 2020. Microsoft then conquered its space – not very desirable, incidentally.
