7 Shocking Facts about Google’s “Quantum Money”: Can Blockchain and Crypto Be Obsolete?

Jakarta, Pintu News – The latest research from Google Quantum AI has caught the attention of the tech and crypto world. They introduced an updated old concept: “Quantum Money”, digital money that cannot be counterfeited because it is protected by the laws of quantum physics. If successful, this technology could replace blockchain, the main foundation of cryptocurrencies like Bitcoin and Ethereum .

Here are 7 key points from this research that are being discussed and gaining widespread attention from the global crypto community:

1. No Longer Blockchain, Digital Money Can Be Secured Through Physics

Google’s research with the University of Texas and the Czech Academy of Sciences proposes a new system called “Anonymous Quantum Tokens”.

According to researcher Dar Gilboa of Google Quantum AI, this digital money is not stored on a ledger like blockchain, but takes the form of a unique quantum object. Source: Decrypt, 2025.

This means that transactions no longer need a global verification system like Bitcoin (BTC), but are instead based on the physical properties of the token itself. This makes it more efficient and energy-efficient.

2. “No-Cloning Theorem”: This Token is Impossible to Counterfeit

Quantum money uses a physics principle called the no-cloning theorem, which states that it is impossible to make a perfect copy of an unknown quantum state.

Unlike digital data that can be copied indefinitely, quantum tokens can only be created and owned once. This is seen as a breakthrough in digital security.

Gilboa explains, “If you have Rp16,719 ($1 equivalent) in quantum form, it is impossible to double it.”

3. A Serious Threat to Old Crypto Like Bitcoin and Ethereum

Some experts warn that legacy cryptos like Bitcoin (BTC) and Ethereum (ETH), which use the ECDSA cryptographic system, are not prepared for the quantum threat.

According to a report by Mysten Labs (2025), blockchains like Solana and Near are more resilient to quantum attacks because they use the EdDSA scheme.

In other words, if quantum computers are advanced enough, the security keys of billions of crypto assets could get compromised.

4. Not Decentralized: Still Need an Authorized Publisher

While promising, Google’s quantum money still relies on centralized parties like banks to issue tokens. According to Gilboa, the system is not trying to compete with crypto entirely as it lacks the decentralized aspect that Bitcoin (BTC) or other altcoins have.

However, this quantum technology has a unique mechanism to prevent publishers from abusing their power, one of which is through a “swap test” that users can use.

5. No Ledger, No Double-Spend

Blockchain was created to prevent “double spending” without a central authority. Quantum money offers a more direct solution.

Since quantum tokens cannot be copied or used twice, transactions are easier to verify without the need for a public ledger.

This makes the process much lighter than proof-of-work crypto systems that require a lot of energy.

6. Unusable, but Potentially Explosive in the Future

According to Gilboa, the quantum money system is still entirely theoretical. It would require large-scale, stable quantum computers, as well as a quantum communications infrastructure that is not currently available.

However, researchers still think the potential of this technology is very high. If successful, it could spur new interest beyond blockchain and conventional cryptocurrencies.

7. Challenging Crypto Solutions: Innovations that Scientists Hunt for

Quantum money shows that blockchain is not the only solution for financial digitization.

According to Gilboa, “It’s a crazy tool that can be used for amazing things. The risk is high, but the reward is also high.”

The concept has received great attention from scientists and the crypto community because it expands the innovation horizon of digital financial technology.

Conclusion

Quantum money is not a direct competitor to cryptos like Bitcoin (BTC), but rather a very different alternative. If proven viable, it could replace the role of blockchain in terms of security and authentication, but still with trust in a central authority.

For now, blockchain and crypto are still the main systems of choice and attention, but the future could well move into the realm of quantum physics.
