U.S. Commerce Department Grants $300M to Quantum Firms; Ethereum and Bitcoin Target Post-Quantum Upgrades

The U.S. Department of Commerce is awarding up to $100 million each to Rigetti, D-Wave, and Quantinuum under the CHIPS Act, taking minority equity stakes in return to support fault-tolerant quantum computing research. Meanwhile, Ethereum has set a December 2029 deadline for achieving quantum resistance across its execution, consensus, and data layers. Bitcoin developers are also advancing BIP-360 and BIP-361 proposals for post-quantum signature migration, with industry consensus suggesting a viable path must be established before 2029.
