Main highlights
- Quantica Tech has announced the development of Quantic Bitcoin (BTCQ), a new cryptocurrency designed to be secure against future attacks from advanced quantum computers.
- This project connects classical and quantum systems using quantum interoperability protocols
- The announcement comes amid major investments from major technology companies such as IBM and Google.
On October 6th, Portuguese quantum computing company Quantica Tech announced the development of Quantic Bitcoin (BTCQ). It is a quantum interoperability protocol for connecting traditional blockchain networks to next-generation computing frameworks.
What is Quantic Bitcoin?
According to the official press release, the BTCQ concept originates from Quantica Tech's proprietary quantum interoperability protocol, which opens the door to communication between classical blockchains and quantum processing systems.
This hybrid architecture allows the network to integrate the benefits of quantum computing for complex tasks such as transaction validation and smart contract execution while maintaining backward compatibility with existing infrastructure.
In the project, Quantum algorithms take inspiration from quantum principles such as superposition and entanglement to process results more efficiently than traditional systems.
Technically speaking, BTCQ operates in a multi-layered structure. Its base layer maintains Bitcoin's proof-of-work consensus mechanism. However, weak cryptographic signatures are replaced with quantum-resistant alternative signatures based on NIST-approved post-quantum standards.
This provides Scholl's algorithm attack that threatens the security of traditional blockchains. During this transition period, networks use emulators to run quantum algorithms on classical hardware. This eliminates the need for access to a quantum computer during preparation for full integration.
“At the basis of Quantic Bitcoin is Quantic Algorithmization, a new philosophy of algorithm design inspired by quantum models. To demonstrate this approach, Quantic Tech successfully applied it to predict the outcome of the latest US presidential election using real-time public data streams. This experiment accurately predicted both the Electoral College and popular vote results and was officially pre-registered with the notary public body,” the company said in an official press release. release.
This ecosystem also uses fractional units called photons, quarks, and bosons that enable microtransactions.
According to an official statement, the company is planning a Simple Agreement for Future Tokens (SAFT) in the second half of 2025. This will give early investors access to deferred rights in BTCQ.
“The company is also considering pre-selling fractional units known as Quantic Bitcoin. Photons, quarks, and bosons mirror Bitcoin's Satoshi, and complementary projects such as Quantica Coin, USDT-Q, and Q-Solana are also in the works, all currently in the maturity stage. ” states the press release.
Ironically, this revelation comes amid growing concerns that advances in quantum computers could compromise the cryptographic security that currently protects cryptocurrencies such as Bitcoin.
Quantum-resistant cryptocurrencies become a new trend
The announcement comes as quantum-secure digital assets gradually become more popular. This new trend was accelerated by the 2025 standardization of post-quantum cryptographic algorithms by NIST.
The Quantum Resistant Ledger (QRL) transitioned to Proof-of-Stake in early 2025 by using XMSS signatures for comprehensive post-quantization protection. After this upgrade, the market capitalization reached $150 million.
Similarly, Algorand integrated Falcon Signature in May 2025. Algorand soared decentralized finance adoption to $2 billion in TVL while protecting blockchain history from possible quantum retroactivity attacks.
Other companies are also building quantum-secure blockchains. For example, Cellframe is launching a new secure node, and QANplatform is collaborating with IBM on a cybersecurity system that combines blockchain and artificial intelligence.
However, this also led to the tension of “harvest now, decrypt later” attacks. This is when hackers steal currently encrypted data and unlock it later when quantum computers become powerful enough.
Many large companies are deeply involved in the race to integrate quantum computing and blockchain. IBM has a program called “Quantum Safe'' that adds quantum-proof security to its powerful computers.
The company is also working with banks such as JPMorgan to develop a new ultra-secure financial record-keeping system. IBM also plans to build a giant quantum computer with 16,000 qubits, the core unit of quantum power.
Similarly, Google has developed a new quantum chip called “Willow” that is better at correcting its own errors. Through its cloud services, Google is enabling other companies to test quantum-secure cryptocurrency ideas. Parent company Alphabet has a $1 billion investment fund focused on projects connecting blockchain and quantum technologies.
