White House Orders Push Quantum Buildout and Encryption Defenses

The White House issued two executive orders on Monday that move in parallel: one to speed up U.S. development of large-scale quantum computers, and another to protect federal systems from the encryption-breaking threat such machines could eventually pose.

The development matters for crypto because Bitcoin, Ethereum and other blockchains rely on cryptographic systems that researchers and industry participants are already studying in the context of future quantum risk. The issue is not that a near-term break was announced, but that governments, technology companies and blockchain communities are preparing for a world in which today’s encryption may need stronger defenses.

One order directs an effort called QC-ADDS to produce a large-scale quantum computer, with the goal of delivering at least one machine to a Department of Energy facility and, where possible, making it available to the scientific community. It also instructs the Pentagon to prioritize next-generation quantum sensor projects and field them by September 30, 2028.

The second order focuses on defensive preparation. It warns that adversaries may collect encrypted data now and decrypt it later if quantum computers become capable enough, a risk often described as “harvest now, decrypt later.” To address that, federal agencies are required to migrate sensitive systems to post-quantum cryptography for key establishment by the end of 2030 and for digital signatures by the end of 2031.

CoinDesk noted that quantum computing has become a recurring topic in crypto after researchers said breaking the elliptic curve cryptography used by Bitcoin and Ethereum could require fewer physical qubits than previously estimated. Google has set a 2029 internal target to migrate its infrastructure to post-quantum cryptography, while Ethereum has set a similar target and other blockchains, including Bitcoin, have been assessing their own defenses.
