Google’s quantum supremacy could mean it is able to perform in seconds what would take a powerful computer 10, years and potentially mean bitcoin, and the encryption that underpins it, could be broken. Qubits, or quantum bits, are the basic unit of quantum information which use the properties of a quantum system, such as the polarization of a photon or the spin of an electron, where as traditional computers store and process data as a series of ‘1’s and ‘0’s. National Review. Details of Google’s so-called «quantum supremacy,» meaning it can solve calculations impossible with traditional computers, were posted to a Nasa website before being deleted, it was claimed by the Financial Times , a business newspaper.
Bitcoin is Naturally Resistant to Quantum Computing
A document published— and later deleted —by NASA a few days ago revealed that we could soon be entering a new technological era: Google has achieved «quantum supremacy»—supposedly. Does that mean that we ehat say goodbye to that sweet cryptography that protects the integrity of Bitcoin and other digital wat Probably not. For starters, sources at Google told Fortune over the weekend that NASA took down the paper because it might have been published without the proper scientific peer review. A scientific publication needs to be evaluated and studied by a panel of experts before its ready for publication. So, it might not even actually be ready.
What to Read Next
In reality, these fears reflect more of an imagined doomsday scenario than a true statement about future events. There are two main reasons why bitcoiners should be skeptical about quantum computing threats to blockchain technology. They are either exaggerated or false. Satoshi Nakomoto knew about the possibility of stronger computer power being able to penetrate encryption, and that is why he built the protocol to withstand attacks. Before delving further into these points, it is important to have knowledge of how quantum computers work, and how they differ from traditional machines.
Quantum Computing versus Traditional Computing
Creating a quantum computer is a massive scientific and engineering challenge. The blockchain is the general ledger to say what happened to each bitcoin over time and where it went. Quantum computer image via Ocmputer. Proof that a phenomenon and the capability to extract power from it exist, but still far from directed use toward useful things. And this summer, the National Research Council NRC of Canada partnered with the University of Waterloo to launch a two-year research initiative for quantum-safe blockchain technology. The result of the hash is a bit integer. For one, blockchain transactions are secured with digital signatures based on elliptic curve cryptography ECC.
