5 Quantum Computing Stocks Set for Huge Price Upside in 2H 2026

Zacks identifies five pure-play quantum computing stocks—D-Wave (QBTS), Rigetti (RGTI), IonQ (IONQ), Quantum Computing Inc. (QUBT), and Quantinuum (QNT)—that have not participated in Wall Street's rally year to date but have significant upside potential in H2 2026. A key catalyst is the Trump administration's June 22 executive orders shifting U.S. quantum policy toward commercialization, technology deployment, and national security applications rather than basic research.

Why it matters: D-Wave (QBTS) is highlighted with a Zacks Rank #2 (Buy), advancing its annealing platform and gate-model computing via its Quantum Circuits acquisition, targeting ~175 physical qubits by end of 2028 and a $20M system order boosting bookings.
