The Nasdaq Composite (IXIC) yesterday tapped its longest win streak in nearly five years.

Yesterday was World Quantum Day, a day dedicated to raising awareness of the physics that powers the quantum computers of tomorrow.

Nvidia's new Ising AI accelerates the speed at which quantum computer outputs get debugged. Nvidia wants a piece of the $11 billion quantum market.

Quantum computing stocks are staging another broad rally on Wednesday morning, with all three major pure-play names climbing for the second consecutive session.

D-Wave Quantum (QBTS) valuation reflects early revenue traction, but overstates scalability and long-term economics given current annealing limitations and rising operating costs. Quantum Computing Inc. (QUBT) trades near cash value, embedding low expectations despite multiple pathways toward scalable photonics manufacturing and broader end-market optionality. Both companies target similar end-state quantum opportunities, but valuation gap heavily favors near-term traction over comparable long-term potential.

Nvidia's Ising line promises to aid certain functions necessary to this type of advanced computing. The Ising models are all open source.

Speaking to Yahoo Finance at the Semafor World Economy Summit, Baratz said: "If I was Nvidia, I'd be shaking in my boots," framing quantum as the next wave of compute power that could eventually undercut traditional AI accelerators.

World Quantum Day, celebrated every year on April 14, is a global initiative to raise awareness about quantum science and its impact on technology, industry and everyday life.

Quantum computing stocks are surging in midday trading on Tuesday, with the sector's three most-watched pure-plays all posting double-digit gains.

D-Wave Quantum enters 2026 with surging bookings, major deals and a strategic acquisition as it accelerates quantum capabilities and expands its market reach.
