How far away is a quantum computer capable of breaking crypto cryptography?

[lingriiddd]

No publicly known quantum computer currently has the number of stable, error-corrected qubits required to run Shor's algorithm against the key sizes used in cryptocurrency. Current estimates from quantum computing researchers suggest a cryptographically relevant quantum computer capable of breaking elliptic curve cryptography would require millions of physical qubits with very low error rates, a capability that leading quantum hardware teams have not yet demonstrated and that most researchers place at least a decade away under current trajectories. However, the timeline has significant uncertainty in both directions, and the standard security recommendation is to begin migrating to quantum-resistant cryptography now rather than waiting until the threat is imminent, because the migration process for global blockchain infrastructure will take years and cannot be completed quickly once a credible threat emerges.

Quantum computers need millions of stable qubits and currently have a few thousand, we have some time but not unlimited

[Patapim]

Quantum discussions in crypto getting more serious lately

[CoffeeZombie]

We still have time… probably

Crypto security might look completely different in 10 years.

Interesting how the industry is already preparing for post-quantum tech.

Most people ignore this topic until it suddenly matters .

Millions of qubits needed sounds far away but tech moves fast.

Future of blockchain security gonna be fascinating honestly.

Feels weird knowing current encryption won’t last forever.

One day “quantum resistant” could become standard everywhere.

Crypto evolving together with technology as always

Not an immediate threat but definitely not science fiction anymore.

The real challenge is upgrading everything in time.

Markets panic fast but infrastructure upgrades move slow

[GummyBear]

Kinda crazy how early Bitcoin was built for a different era.

Quantum computing really sounds like a final boss for cybersecurity
