Chinese researchers have "reportedly" cracked "military-grade encryption" using a quantum computer, marking a significant threat to global security?

The D-Wave system used in this breach targets Substitution-Permutation Network (SPN) algorithms commonly found in sectors like military and finance.

While no specific passcodes were cracked, this breakthrough suggests that quantum computing is rapidly advancing beyond traditional encryption defenses.

The breakthrough hinges on the quantum annealing algorithm, leveraging quantum tunneling effects. Unlike traditional algorithms, which explore every possible solution path, this method allows quantum systems to 'tunnel' through computational barriers to reach solutions faster. Researchers also integrated classical algorithms like Schnorr and Babai for a hybrid approach to cracking encryption.

Does this development present a potential leap in quantum computing applications, particularly in cryptography? As quantum hardware evolves, encryption methods may need urgent reconsideration to protect sensitive information?

It is now urgent that Google , Microsoft and Apple and other major western technology companies to act in switching to quantum hardened encryption but to ensure is still strong in standard computers.
