US Government Takes Equity in Rigetti, Quantum Memory Breakthrough Achieved

• The U.S. government will acquire an equity stake in Rigetti Computing via up to $100 million in CHIPS Act funding, setting a precedent for direct investment in quantum firms. This complements the White House's $2.2 billion pledge for 2028 fault-tolerant computing and Microsoft's accelerated post-quantum cryptography (PQC) transition by 2029.

• Researchers at the University of Calgary have achieved the first coherent link between a chip-integrated quantum dot and solid-state quantum memory, a critical step for scalable quantum networks. This system utilizes InAsP/InP nanowire quantum dots and erbium-doped fiber for deterministic photon storage.

• Flatiron Institute research surprisingly indicates a classical approximation can perform comparably to the quantum approximate optimization algorithm (QAOA) for spin glass optimization. This challenges the notion of universal quantum advantage, opening doors for effective hybrid quantum-classical solutions.
