D-Wave Quantum reported record Q1 2026 bookings of $33.4 million (up 2,000% YOY) and strong QCaaS revenue growth, but the stock fell 7% post-earnings due to revenue of $2.9 million (down 80% YOY) and widening losses. Despite weak top-line performance, the company maintains $588 million in cash and shows progress toward sustainable profitability through recurring revenue streams.

D-Wave Earnings Looked Weak, But Investors May Be Missing This

QSE launched QPA v2, an enterprise post-quantum cryptographic migration platform designed to help organizations transition to quantum-safe cryptography ahead of regulatory deadlines. The platform offers AI-enhanced assessment, inventory analysis, and real-time visibility into quantum readiness. This comes as NIST finalized post-quantum cryptography standards and the NSA's CNSA 2.0 framework requires quantum-safe implementations by 2027-2035.
