IONQ shares rose 12.27% after hours to $45.74 after announcing a quantum error correction breakthrough. RGTI, QBTS, and QUBT also gained. The technology aims to reduce errors in quantum computing. IONQ tested it on circuits simulating 408 logical qubits, adding minimal execution time.

Quantum computing stocks IonQ, Rigetti, D-Wave, and Quantum Computing have seen significant gains over two years, with insiders selling $895.1M more than they bought. Insiders' selling may be for tax or diversification reasons, but the lack of buying could signal caution. Their high P/S ratios suggest potential overvaluation.

Quantum Computing Inc. (QUBT) shares rose 9.16% in a week, driven by bullish options activity and a new three-year partnership with Hamad Bin Khalifa University in Qatar. The deal involves providing cloud access to its Dirac-3 quantum computing system and installing hardware in Qatar. Analysts rate the stock a Moderate Buy with potential upside, according to TipRanks.

President Trump signed two orders to accelerate U.S. quantum tech development and enhance cybersecurity. The first aims for a functional quantum computer by 2028, while the second mandates quantum-resistant encryption by 2031. IBM, IONQ, and QUBT stocks rose 4-6% after-hours. The Department of Commerce also allocated $2 billion for commercial quantum development.

IonQ's stock rose 9% after announcing quantum optimization progress with NVIDIA, Oak Ridge National Laboratory, and the University of Tennessee. D-Wave, Rigetti, and Quantum Computing Inc. also gained 8%, 7%, and 5% respectively, in sympathy. The Defiance Quantum ETF increased 2%. IonQ's advance is within a broader losing month. NVIDIA's involvement validates IonQ's hybrid quantum-classical approach.

Quantum Computing Inc. (QUBT) signed a 3-year agreement with Hamad Bin Khalifa University in Qatar to collaborate on quantum computing, sensing, and communications, including access to its Dirac 3 system. The deal positions QUBT in building Qatar's quantum hub, potentially boosting its investment narrative. However, the company faces risks such as modest revenue, material losses, and rising expenses. Analysts project significant revenue growth and earnings improvement by 2029, with a potential 1

Quantum computing stocks fell midday Wednesday as Federal Reserve rate-hike odds increased.
