Researchers have reduced the quantum computing power needed to crack RSA encryption tenfold to approximately 100,000 qubits, down from earlier estimates of millions, by using a new qubit arrangement scheme called qLDPC code. While quantum computers capable of breaking common encryption could be built within the decade, experts caution that practical implementation faces significant engineering challenges in connecting distant qubits.
