Google has set a clear goal: it wants to roll out post-quantum cryptography across its products by 2029.
This is a big step, because it shows how seriously the company is taking the rise of quantum computing. Google says advances in hardware, better error correction, and faster progress overall mean today’s encryption may not stay safe forever.
In simple terms, the locks we use today to protect data—like passwords, digital signatures, and secure connections—could eventually be broken by powerful quantum machines. That’s why Google says the shift to “quantum-safe” security needs to start now, not later.
The 2029 deadline is important because it’s one of the first firm timelines from a major tech company. It also sends a message to the rest of the industry: prepare early.
This concern isn’t just limited to big tech—it’s also growing in crypto.
The Ethereum Foundation is already working on making Ethereum resistant to quantum attacks at the protocol level, with a similar target timeline around 2029.
Other networks are taking different approaches. Solana has introduced quantum-resistant vaults that use advanced signature methods, though users need to move their funds into special wallets to use them.
Meanwhile, the Bitcoin community is still divided. Some experts, like Adam Back, believe the threat is still far away. Others, including Ethan Heilman, support proposals like BIP-360 to start preparing now.
Overall, the direction is clear. Quantum computing is no longer a distant idea—it’s a growing reality. And companies like Google are trying to stay ahead of the risk by upgrading security before it becomes a real problem.
