IBM scientists entangled 120 qubits in a single coherent “cat state,” a record-breaking feat in quantum computing.

If quantum computers capable of breaking Bitcoin’s algorithm were around today, the network’s security could already be compromised without anyone realizing it.

Bitcoin relies on several algorithms to secure the coin from theft. Prominent among these is the Elliptic Curve Digital Signature Algorithm (ECDSA). An ECDSA employs asymmetric encryption to generate ...
