I remember a time in my life where many of these things may as well have been science fiction. And now they are an everyday part of life. In the near future, quantum computers will be too.

Every few months I update what I call the Quantum 8 — my personal ranking of the eight best quantum stocks available in the market right now. In this episode I walk through the full list, explain why the rankings changed, and break down the technical progress, revenue growth, roadmap strength, and market setup behind each company.  This update includes a new photonics name in Xanadu, a reshuffling of major players like Quantum Emotion, Rigetti, D-Wave, IBM, Google, Infleqtion, and IonQ, and a fresh look at how public market performance lines up with real technical milestones. I also explain why I think software, sensing, photonics, superconducting, neutral atom, and post-quantum security all matter in the bigger picture of the quantum revolution.  Covered in this video: Xanadu joins the Quantum 8 after going public and posting strong revenue growth Quantum Emotion’s quantum randomness and TSM-related progress Rigetti’s 108-qubit system and superconducting outlook D-Wave’s revenue surge, missile defense work, and annealing moat IBM’s march toward fault-tolerant quantum computing Google’s growing quantum ambitions, including neutral atom interest Infleqtion’s commercial traction in sensing, timing, and space IonQ’s acquisitions, roadmap, revenue expansion, and why it takes the top spot  Visit thequantumbull.com/invest to track the historical Quantum 8 rankings and follow along with how the list evolves over time.  00:00 – Intro: What Is the Quantum 8? 01:00 – #8 Xanadu and the Photonics Case 04:24 – #7 Quantum Emotion and True Randomness 08:09 – #6 Rigetti’s 108-Qubit System 12:10 – #5 D-Wave’s Revenue Growth and Annealing Edge 17:42 – #4 IBM and the 2029 Fault-Tolerant Goal 20:45 – #3 Google’s Quantum Push and Neutral Atom Interest 24:28 – #2 Infleqtion’s Commercial Momentum 28:34 – #1 IonQ Takes the Top Spot 33:36 – Final Thoughts on the Quantum 8

Rigetti vs IQM: Superconducting Quantum Showdown In today’s episode, we compare two major superconducting quantum computing players: Rigetti (USA) and IQM (Finland). We break down their technology, financials, roadmaps, and positioning to answer one key question: Who is actually leading in superconducting quantum computing right now? Key topics: • What superconducting quantum computing is and how it works • Strengths: fast gate speeds, scalable manufacturing • Weaknesses: extreme cooling, short coherence times, noise challenges  • Rigetti (RGTI) • Chiplet architecture strategy • 100+ qubit roadmap delays into 2026 • $100M UK expansion + system sales • Strong partnerships (Nvidia, USAF, IBM) • IQM (Private / Europe) • 150-qubit systems and growing • 30+ systems built, 19 sold • ~$35M revenue and $100M+ bookings • Roadmap to 1000+ qubits by early 2030s • Key insight: • IQM may currently lead in scale and commercialization • Rigetti remains a high-upside U.S. proxy tied to the broader ecosystem This is a critical comparison as superconducting remains one of the dominant modalities alongside players like IBM and Google.

Q-Day Timeline Just Got Shorter Today’s episode covers one of the most important shifts in quantum computing history — the rapid acceleration toward “Q-Day,” the moment quantum computers can break modern encryption. Key developments: • Google Quantum AI Paper (March 2026) • Suggests elliptic curve cryptography could be broken with less than 500,000 qubits • Attack timelines measured in minutes, not days • Introduced zero-knowledge proof disclosure instead of revealing full methods • Shrinking Timeline Trend • 2025: ~1,000,000 qubits (Google estimate) • Early 2026: less than 100,000 qubits (new architecture) • Now: ~500,000 qubits for crypto attacks • Clear pattern: more power from fewer qubits • Caltech / John Preskill Breakthrough • New architecture could enable useful quantum computing with 10,000–20,000 qubits • Error correction reduced dramatically (~1000 → ~5 qubits per logical qubit) • Major Implications • Quantum threat to Bitcoin, Ethereum, and global encryption • Governments now coordinating research disclosure • Beginning of a post-quantum cybersecurity transition • Core Thesis The biggest shift is not hardware — it’s algorithmic efficiency + error correction. Quantum computers don’t need millions of qubits anymore. This is a turning point moment for quantum computing, cybersecurity, and global infrastructure.
