Quantum computing has shifted from theoretical promise to practical deployment as AT&T, one of the largest telecommunications companies in the United States, began integrating advanced quantum processors into its core business operations. This development comes at a time when Bitcoin‘s price dropped toward $63,000, heightening concerns over the vulnerability of current blockchain encryption.
Quantum breakthrough accelerates real-world tasks
AT&T recently expanded its contract with D-Wave Quantum Inc., a Canadian company specializing in quantum computing hardware and software. The collaboration allowed AT&T to apply quantum annealing technology to its complex network optimization algorithms, drastically improving computational speed.
Tasks that previously took one hour to solve can now be completed in just 15 seconds, showcasing a leap in operational efficiency. Following the announcement, shares of D-Wave Quantum (QBTS) surged above $18.10 in premarket trading.

Bitcoin slide and quantum threat reignite security debate
While quantum technology advanced, Bitcoin experienced a sharp decline, nearing the $63,000 level. This price drop triggered approximately $100 million in forced liquidations across trading platforms. Multiple factors contributed to the decline, including a fall in South Korea’s KOSPI index, heavy selling in the global semiconductor sector, and investor caution ahead of the upcoming U.S. Federal Reserve meeting.
The recent price movement has also reignited worries about the future security of blockchain systems. Eddy Zervigon, CEO of Quantum Xchange, described cryptocurrencies as a “canary in the coal mine” regarding quantum risks, emphasizing that blockchain networks, due to their decentralized architecture, could become early targets of quantum attacks.
Cryptocurrencies, because of their decentralized nature, could be seen as the first “canary in the coal mine” when quantum threats challenge legacy encryption.
Timeline to quantum impact narrows
Research and industry updates indicate the timeline for quantum computers capable of breaking blockchain encryption may be shortening. Google scientists have reduced their estimate of the resources needed to crack Bitcoin’s underlying cryptography by a factor of 20, now believing fewer than 500,000 physical qubits could be sufficient.
At the same time, the U.S. Department of Energy expects a powerful quantum computer could emerge within the next three years. Industry leaders such as IBM and Microsoft have announced preparations for the launch of cryptographically relevant quantum systems by 2029, intensifying the urgency for blockchain communities to adapt.

| Milestone | Institution | Target / Estimate |
|---|---|---|
| Processors integrated in business | AT&T / D-Wave | 15 sec task completion |
| Physical qubits needed to crack Bitcoin | <500,000 | |
| Powerful quantum computer expected | US Department of Energy | Within 3 years |
| Cryptographically relevant systems | IBM, Microsoft | By 2029 |
Amid this backdrop, analysts question whether the Bitcoin ecosystem will be able to implement cryptographic upgrades quickly enough to protect against emerging quantum risks.
AT&T’s integration of quantum solutions has shown that the quantum era is now part of real-world business. For blockchain networks such as Bitcoin, the urgent challenge is to reach consensus on encryption upgrades before the arrival of quantum-capable computers.
