Shares of several quantum computing companies, including IonQ, Inc. ( IONQ ) , Quantum Computing Inc. ( QUBT ) and Rigetti Computing, Inc. ( RGTI ) , are trading higher Monday as excitement builds around the quantum computing sector. Here’s what you need to know.

What To Know: IonQ ( IONQ ) shares are up by more than 25% at the time of writing. The company recently showcased its ion trap technology, which forms the foundation of IonQ's ( IONQ ) quantum computers.  IonQ also discussed go-to-market partnerships and commercial momentum in the quantum space at Q2B24 last week.

IonQ ( IONQ ) has also secured notable contracts, such as a $54.5 million deal with the U.S. Air Force Research Lab and partnerships with the South Korean government and Zapata Computing in recent months. This visibility potentially boosts investor confidence in the quantum sector as a whole, increasing interest across the industry.

Quantum Computing ( QUBT ) shares are up by more than 60% on Monday. The company recently announced its second purchase order for its thin film lithium niobate (TFLN) photonic chip foundry from the University of Texas at Austin.

The collaboration supports advanced research into chip-scale acoustic and cross-domain microsystems using Quantum Computing’s scalable TFLN processes, highlighting the technology's potential in next-generation photonics, signal processing and quantum applications. Fulfillment of the purchase order is expected in the first quarter of 2025.
