Quantum computing stocks are surging in midday trading on Tuesday, with the sector’s three most-watched pure-plays all posting double-digit gains. IonQ (NYSE:IONQ | IONQ Price Prediction) stock is up 18% today, D-Wave Quantum (NYSE:QBTS) stock has climbed 15%, and Rigetti Computing (NASDAQ:RGTI) stock gained 12%. The coordinated move is reigniting the quantum super-cycle debate that dominated headlines late last year.
The rally arrives against a sobering year-to-date backdrop. IONQ stock is still down 22% year-to-date, QBTS is down 35%, and RGTI has shed 23% since January. Today’s move looks like a sharp snapback within a broader downtrend, which means the question of staying power matters as much as the headline numbers.
IonQ’s Cambridge Partnership and Defense Speculation Drive the Lead
IonQ is the clear leader in today’s session, with IONQ stock trading at $35, up from $29.76 at yesterday’s close. The primary catalyst is a new innovation center agreement with the University of Cambridge, which adds institutional credibility to IonQ’s growing global footprint. Ongoing speculation around IonQ’s potential role in national defense and AI-driven quantum infrastructure is amplifying the move.
The fundamentals give the bulls something real to work with. IonQ posted Q4 2025 revenue of $61.89 million, a 429% year-over-year increase that beat estimates of $40.26 million by a wide margin. Full-year 2025 revenue reached $130.02 million, and management guided for $225 million to $245 million in 2026 revenue.
A $60 million QuantumBasel contract over four years and a world-record 99.99% two-qubit gate fidelity milestone round out the recent catalyst stack. That said, significant options activity and retail debate over dilution and cash burn are adding volatility to the move.
Sentiment composite data shows IonQ carrying a bullish score of 64.27 with medium confidence, supported by a social media score of 68 and a news score of 60.53. Analyst consensus sits at a price target of $65.29 with 10 buy ratings and 3 hold ratings.
D-Wave’s Dual-Platform Bet Attracts Institutional Eyes
D-Wave Quantum stock is trading at $17, up from $14.65, as investors revisit the company’s dual-platform roadmap combining annealing and gate-model quantum computing. The acquisition of Quantum Circuits Inc. gave D-Wave a gate-model capability it previously lacked, broadening its competitive positioning against pure gate-model rivals. A €10 million Advantage2 contract in Italy and a $20 million system purchase by Florida Atlantic University have reinforced the commercial pipeline narrative.
The bookings story is the most compelling near-term data point. D-Wave reported Q4 bookings of $13.4 million, up 471% sequentially, and Q1 2026 year-to-date bookings exceeded $32.8 million. The company holds $635.35 million in cash, which gives it meaningful runway.
However, D-Wave Quantum’s Q4 2025 revenue came in at just $2.75 million, missing estimates by 28%, so the gap between bookings momentum and recognized revenue is one investors should watch closely.
Rigetti’s Hardware Deployments Put It Back on the Radar
Rigetti Computing stock is up to $17 from $15.13, driven by a combination of hardware deployment news and retail momentum. An $8.4 million C-DAC order for a 108-qubit system slated for H2 2026 deployment and $5.7 million in Novera system orders with Q1 2026 shipments represent tangible commercial progress. A Novera QPU delivery to a Japanese research organization is expected this month, adding an imminent catalyst.
Rigetti’s revenue picture is more challenging than its peers. Full-year 2025 revenue was $7.09 million, down 34% year-over-year, and Q4 2025 revenue of $1.87 million missed estimates by 22%. The company does carry $589.83 million in cash and investments and a $35 million Quanta Computer private placement that signals some institutional confidence.
Reddit sentiment for RGTI stock registered a bullish score of 68 in early April, consistent with the retail enthusiasm powering today’s move.
Sector Rotation or Super-Cycle Restart?
The synchronized move across all three names points to sector rotation rather than company-specific news alone. Readers who want deeper background on how these three companies compare on fundamentals can reference a prior comparison of these three quantum computing stocks that examined their relative positioning in detail. The macro setup, including renewed interest in AI infrastructure and defense-adjacent technology spending, is providing a tailwind that lifts all three simultaneously.
No matter how you slice it, the year-to-date losses across IONQ, QBTS, and RGTI stocks mean today’s buyers are stepping into stocks that remain well below their recent highs. Watch for whether today’s gains hold into the close, and whether IonQ’s conference activity or any follow-on contract announcements extend the momentum through the week.
