Bitcoin at risk? The Quantum Internet is closer due to studies of a Brazilian woman

The implementation of a quantum internet may be closer due to the studies of a Brazilian woman.

This way, an unpublished study by northeastern Brazilian Samuraí Brito, it was possible to discover that the optical fibers that today support the internet will not account for quantum communication on a global scale.

New discovery of ‚forbidden light‘ science can revolutionize quantum computing and destroy Bitcoin?

The study of the Northeast was published in one of the most important magazines of the scientific world the „Physical Review Letters“ and paved the way for new studies that already part of the point of discovery of the Brazilian, that is, „forget about fiber optics“.

Besides it reveals the lack of structure of the current optical fibers to support a quantum internet the researcher proposes the first model of networks for the quantum internet and, through numerical simulations, proves that to create it we will need a different structure from the current one.

However, Brito, in search of a solution to make possible the new Internet standard suggests the creation of satellites distributors of quantum entanglement.

However, the proposal is still being based on another study.
Quantum Computing

Computing and the quantum internet are themes that divide the communication of developers and enthusiasts of cryptomoedas and blockchain.

While some believe that implementing a quantum computer could harm the security of Bitcoin’s blockchain, others argue that this is nothing more than senseless speculation.

About quantum computing, last year the former Bitcoin Core developer Peter Todd called Google’s feat of „quantum superiority“ – a computer that solved an equation that would take 10,000 years in just 3 minutes and 20 seconds – as „a primitive type of quantum computing that is far from breaking Bitcoin’s encryption“.

However, others, including Deloitte, are not so sure.

End of Bitcoin? Chinese successfully send data on ‚quantum internet

The accounting firm’s website states that current technology in quantum computing makes 25% of all Bitcoin in circulation vulnerable to attack. If enough coins were stolen, the market could potentially break, undermining confidence in cryptomime.

For Andreas Antonopoulos, the quantum supremacy announced by Google has no impact on Bitcoin, „Nothing really happens,“ he summarized.
Just in case

Last year, although many developers said that quantum computing would have no impact on Bitcoin, Ethereum and other cryptocaps, developers at the core of these cryptoactives stated that they are already preparing both BTC and Ether for this future scenario.

According to Pieter Wuille, BTC developer something around 64 thousand Bitcoins could be affected by the power of quantum computing that would have the potential to ‚discover‘ the private key of one user per user with a quantum attack and thus have access to the resources.

However, the power of quantum computing would not be able to ‚destroy‘ the blockchain or make any ‚attack‘ on it.

But to preserve not only the potential 64 thousand bitcoins but the whole network, the Bitcoin Core developers, according to Wullie already study a PQC security signature scheme. The same happens with Ethereum who, in turn, would be more affected, according to Justin Ðrake, by a ‚quantum attack‘.

The topic was even discussed at the Ethereal Ethereum Summit in 2019, when Ðrake presented the concept of Ethereum 3.0, in which, in partnership with the University of California, he developed a program called SNARGs that does not use SHA256 encryption but ‚combines‘ different types of encryption.

Development

Recently, in June, scientists in China were able to exchange an encryption key at a distance of 1,120 kilometers using quantum entanglement, exceeding the best previous attempt by 1,000 kilometers. Further advances in technology may mean that users can authorize transactions outside the Internet.

In terms of lost passwords, the technology would have the ability to go through more permutations than today’s best machines to find the unencrypted passwords or even reverse a hash.

What is Quantum Computing and how Bitcoin and cryptomaps are preparing for the future

In addition, recently a new type of superconductor, called β-B2Pd has been discovered and, according to the scientists responsible for its revelation, it can revolutionize the development of quantum computing.
