President Donald Trump signed two quantum executive orders on Monday, accelerating federal adoption of post-quantum cryptography and advancing quantum computing. The cryptography order sets a 2031 deadline for federal systems to transition to quantum-resistant digital signatures, earlier than the previous 2035 target. A companion order aims to build a powerful quantum computer within five years. These moves revive concerns about quantum threats to Bitcoin and cryptocurrencies, which rely on elliptic-curve signatures that quantum computers running Shor's algorithm could break. The 'harvest now, decrypt later' strategy poses risks to crypto holdings with exposed public keys. However, experts note that practical quantum attacks remain distant; Google's Willow chip has only 105 qubits, far from the estimated 1.9 billion needed to break Bitcoin's key within a block window. NIST has already finalized post-quantum standards, and Bitcoin developers have proposed migration plans. Markets showed little reaction, with Bitcoin trading near $64,200. The orders directly bind federal agencies, not decentralized networks, but the U.S. government holds a Strategic Bitcoin Reserve established in March 2025.

Key facts

• Trump signs two quantum EOs: one for post-quantum crypto migration by 2031, another for quantum computing.
• Federal systems must adopt quantum-resistant key establishment by end of 2030, digital signatures by 2031.
• Quantum computers could break Bitcoin's ECDSA signatures via Shor's algorithm, threatening exposed keys.
• NIST finalized three post-quantum standards in August 2024; Bitcoin migration plans exist but are not urgent.
• Google's Willow chip has 105 qubits vs. estimated 1.9 billion needed to break Bitcoin's block window.
• Bitcoin trades near $64,200; U.S. Strategic Bitcoin Reserve established March 2025.
