China activates its quantum weapon: Is this the first step to undermine Bitcoin's security and erase it from the map?

A group of Chinese researchers has managed to compromise a cryptographic key using a commercially available 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 advancements.

A recent experiment conducted in China could change this reality. The use of quantum computing to compromise protective keys reveals a concerning scenario: how long until even Bitcoin is reached?

What was surprising was not just the result, but the method: they used an accessible quantum computer called D-Wave Advantage, equipped with 5,760 qubits.

This computer achieved what a conventional one could never do in reasonable time: factor large numbers, the basis of RSA encryption, with the help of a procedure called quantum annealing. This method leverages phenomena such as entanglement and quantum superposition to optimize calculations and solve problems of enormous complexity.
