PsiQuantum’s Chicago project has moved into a more visible construction phase as the company pursues a one million-qubit system. That target is central to its plan for a commercially useful machine.
Some market participants believe fast progress in quantum computing could eventually challenge the cryptographic systems that protect Bitcoin wallets and transactions. Others say the threat remains distant and manageable.
PsiQuantum Advances Million-Qubit Quantum Computing Project
PsiQuantum co-founder Peter Shadbolt said construction is now underway at the company’s Chicago site. In a post on X, he shared that about 500 tons of steel had been erected in six days to support the planned system.
The company had earlier said it raised $1 billion for the project. It is also working with Nvidia on infrastructure designed to support fault-tolerant systems, which are considered essential for useful quantum computing at scale.
The facility is designed to host one million qubits, a level many researchers view as a major milestone in quantum computing. PsiQuantum said this scale could support practical applications and help power next-generation AI systems.
At the same time, the announcement has revived concerns over whether future quantum computing systems could weaken Bitcoin’s cryptography. The debate remains unsettled, with researchers, developers, and crypto executives offering different timelines.
PsiQuantum Pushes Toward Large-Scale Quantum Computing
PsiQuantum is positioning itself as one of the leading companies in the race to commercialize quantum computing. Its latest facility is intended to move the technology beyond laboratory testing and into real-world use.
The company says one million qubits could deliver processing power far beyond conventional machines. That leap could make quantum computing useful in areas where classical systems face limits, including chemistry, materials science, and advanced modeling.
Why One Million Qubits Matters
Researchers have long argued that scale is one of the biggest barriers in quantum computing. Small experimental systems can demonstrate scientific progress, but they are not enough for broad commercial use.
A machine with one million qubits would mark a major step toward practical deployment. It could also improve error handling, which remains one of the hardest technical problems in quantum computing today.
Bitcoin Security Concerns Return
The latest progress in quantum computing has again raised questions about Bitcoin’s long-term security. Some members of the crypto community warn that future quantum machines may eventually derive private keys from public keys, putting certain wallet types at risk.
These concerns are strongest around older wallets and unspent transaction output addresses that have exposed public keys. Many of these coins date back to Bitcoin’s early years and are seen as more vulnerable in a quantum attack scenario.
Experts Remain Divided on the Timeline
Not everyone agrees that the risk is near. Some Bitcoin advocates believe it will not pose a practical threat for many years.
Blockstream CEO Adam Back has argued that such systems are unlikely to endanger Bitcoin in the near term. That view contrasts with more cautious voices calling for early preparation as it continues to improve.
Bitcoin Developers Consider Possible Responses
Developers have started discussing whether Bitcoin should prepare for quantum-era threats before they become urgent. One possible path is a future hard fork that would move the network toward stronger protection methods.
That process would be complex. It would likely require broad agreement across the Bitcoin ecosystem. For now, the discussion remains at an early stage, but the pace of its research is keeping the issue active.
Estimates on Bitcoin Vulnerability Differ
The number of qubits required to crack the current encryption schemes is also a matter of ongoing debate. Estimates are now coming down as the methods and devices used to arrive at them are getting better.
A scientific preprint has recently proposed that it may take 100,000 qubits to crack 2048-bit encryption schemes. Bitcoin has 256-bit encryption.
Current Exposure May Be Limited
Research from CoinShares estimated that about 10,230 Bitcoin are both quantum-vulnerable and stored in addresses with publicly visible cryptographic keys.
That amount is meaningful, but not necessarily market-breaking. CoinShares argued that even a selloff of that size would resemble a routine trade in Bitcoin’s broader market structure.
PsiQuantum Says It Has No Plan to Target Bitcoin
PsiQuantum has also tried to address some of the concern directly. In July, co-founder Terry Rudolph said the company has no intention of using its technology to derive private keys from public keys.
He said such activity would be difficult to conceal inside a company with hundreds of employees. His comments were aimed at easing fears that the firms are actively building tools to target crypto networks.
Conclusion
PsiQuantum’s new facility marks another major step for quantum computing as the sector pushes toward practical use at scale. The one million-qubit goal reflects how quickly the industry is moving from theory toward infrastructure.
At the same time, the announcement has reopened an important debate for Bitcoin and the wider crypto market. It may not pose an immediate threat, but its steady progress is forcing developers and investors to think more seriously about long-term security.
Appendix Glossary of key terms
Qubits: These are the basic building blocks of quantum computing that allow for the existence of more than one state simultaneously.
Fault tolerance: This is the ability of quantum computing to continue working even in the presence of error.
Cryptography: This is the way in which information, transactions, and communications in the digital world are made secure using mathematics.
Bitcoin wallets: These are the digital tools that allow users to store the information necessary for spending of their Bitcoin assets.
UTXO: This stands for unspent transaction output, which is the Bitcoin that is unspent but has been received.
Public key: This is the cryptographic code that is publicly available and is necessary for the receipt of digital assets.
Private key: This is the cryptographic code necessary for the spending of digital assets.
Frequently Asked Questions About Quantum Computing
1- What is quantum computing?
A new, advanced form of computing that uses quantum bits, or qubits, to process information.
2- Why is PsiQuantum’s project important?
PsiQuantum’s goal is to build a one-million-qubit system, which is considered an important step toward practical quantum computing.
3- Which Bitcoin wallets are at greatest risk?
Those with exposed public keys, particularly older UTXO addresses, are considered the most at risk of the quantum attack that may occur in the future.
4- Are developers already working on defenses?
The conversation currently being had in the Bitcoin tech community suggests that post-quantum solutions are indeed being considered, although no one knows when.
