China activates its quantum weapon: Is this the first step to undermine Bitcoin's security and wipe it off the map? A group of Chinese researchers has managed to breach a cryptographic key using a commercial quantum computer. Although Bitcoin remains safe for now, the study reveals that the cryptocurrency ecosystem is closer than ever to a real threat driven by quantum advancement. The security of cryptocurrencies has always relied on complex encryption algorithms that, in theory, would take millions of years to decipher. However, a recent experiment carried out in China could change this reality. The use of quantum computing to breach protective keys reveals a concerning scenario: how long until even Bitcoin is reached? The finding was led by Wang Chao, a professor at Shanghai University, and published in the Chinese Journal of Computers. His team managed to decipher a 90-bit RSA key, a technology still present in various digital security systems. What was surprising was not only the result, but the method: they used an accessible quantum computer called D-Wave Advantage, equipped with 5,760 qubits.$FUN
