Relief came Wednesday evening when the Wall Street Journal reported that several quantum companies including IonQ Inc. (NYSE:IONQ), Rigetti Computing, Inc. (NASDAQ:RGTI) and D-Wave Quantum, Inc. (NYSE:QBTS) are in discussions with the U.S. government that could see Washington become a shareholder in exchange for financial support. 

Funding awards are expected to start at $10 million each. Other firms, such as Quantum Computing Inc. (NASDAQ:QUBT) and Atom Computing, are reportedly considering similar arrangements.

Quantum stocks ran up on Thursday following the report, but they had a lot of ground to make up from the dive earlier in the week. 

SEALSQ – LAES 

SEALSQ Corp. (NASDAQ:LAES) unveiled its Quantum Shield QS7001, the first secure chip to embed NIST-standardized post-quantum cryptography algorithms directly at the hardware level.

SEALSQ also surpassed and sustained a $1 billion market cap and confirmed that its stock will begin trading on the Nasdaq Global Select Market on Oct. 27.

On Tuesday, IonQ claimed it achieved 99.99% two-qubit gate fidelity, highlighting the achievement as a new global benchmark in computational accuracy and scalability.
