  • Are We Computing Quantum in the Wrong Base? with Ivan Deutsch

    Are We Computing Quantum in the Wrong Base? with Ivan Deutsch
    Apr 27 2026
    Are We Computing Quantum in the Wrong Base? with Ivan DeutschIvan Deutsch is Distinguished Regents' Professor of Physics and Astronomy at the University of New Mexico and the founding director of CQuIC, the Center for Quantum Information and Control. Along with his longtime collaborator Poul Jessen, Ivan helped lay the theoretical foundations for neutral-atom quantum computing in the 1990s: trapping individual atoms in optical lattices, cooling them to near absolute zero, and shuttling them in parallel to perform quantum logic. The companies commercializing those ideas today — QuEra, Pasqal, Atom Computing, Infleqtion, and the newly announced Aurora out of Caltech — are building on architectural concepts that trace directly to his group's early papers. His 9,600+ citations across quantum information, atomic physics, and quantum control place him among the most-cited theorists in the field.The reason to talk to Ivan now is that he has been making a quietly heterodox argument: every one of those commercial platforms encodes information in two energy levels of an atom that has ten or sixteen, and Ivan thinks the field should be asking whether that's the right choice — not for information density, which is only a logarithmic gain, but for fault tolerance. This conversation goes deep on qudits, spin cat codes, and the co-design philosophy that has shaped Ivan's career at the interface between theory and experiment, ions and neutral atoms, and academia and industry. If you are following neutral-atom hardware, fault-tolerant quantum error correction, or the emergence of regional quantum ecosystems, this episode is essential.What You'll LearnWhy neutral atoms were the "underdog cousins" of trapped ions — and the precise trade-off at the heart of a 30-year rivalry: ions are great and terrible because they're charged; neutral atoms are great and terrible because they're neutralWhat the original neutral-atom quantum computing paper actually got right: the parallel atom-movement architecture now central to QuEra, Atom Computing, and Infleqtion's roadmaps was already there — even if the Rydberg blockade's full power wasn't appreciated until laterWhat qudits are and why fault tolerance, not information density, is the compelling argument: the information gain from base-2 to base-10 is only logarithmic, but co-designing error-correcting codes with the physical structure of the hardware may be transformativeHow spin cat codes work: using the extra energy levels inside a single atom for error redundancy, directly analogous to bosonic cat codes in microwave cavities, with fault-tolerant thresholds that may surpass standard qubit surface codesWhy biased error correction matters: real physical errors in neutral atoms aren't arbitrary, and codes designed around the dominant error channels — including leakage and erasure — can dramatically outperform worst-case generic schemesHow leakage becomes an asset: when population escapes the qubit subspace into other levels, detecting that escape converts it from an unknown error into an erasure error, which is far easier to correctWhy working at interfaces is where the creative work happens: Ivan's career has been built at the boundary between theory and experiment, between ion-trap and neutral-atom communities, and now between research and industryHow New Mexico became a quantum hub: the founding of QNM-I, the partnership with Colorado, and the Elevate Quantum Tech Hub — turning decades of national-lab and university strength into an actual industrial ecosystemResources & LinksGuest LinksIvan Deutsch — CQuIC Faculty Page — Research profile and publication list at the Center for Quantum Information and Control at UNMGoogle Scholar Profile — 9,600+ citations across quantum information, atomic physics, quantum optics, and quantum controlNSF Q-SEnSE Research Profile — Ivan's role in the NSF quantum sensing and engineering centerKey PapersQuantum optimal control of ten-level nuclear spin qudits in Sr-87 (LANL/CQuIC) — The theoretical demonstration of arbitrary SU(10) maps in strontium-87 with average fidelity ~0.9992; the core technical result behind the qudit computing program discussed in the episodeSpin-cat code paper (ResearchGate) — The fault-tolerant encoding proposal that embeds a qubit in a large-spin qudit, analogous to bosonic cat codes; fault-tolerant thresholds that surpass standard qubit-based encodingsTalks & ContextIMSI Talk — "Neutral Atom Quantum Computing with Nuclear Spin Qudits" — Ivan's accessible lecture-format talk on the full qudit computing research program; a good companion to the episodeQuanta Magazine Q&A with Ivan Deutsch (2015) — Still the most accessible public articulation of his philosophy on qudits and computationEcosystemQuantum New Mexico Institute Launch (Jan 2024) — The founding of the joint UNM/Sandia/LANL institute Ivan establishedUNM/QNM-I Ecosystem Update (Feb 2026) — The current state of the New Mexico ...

  • Quantum Chemistry's Classical Limits with Garnet Chan

    Quantum Chemistry's Classical Limits with Garnet Chan
    Apr 20 2026
    Your host, Sebastian Hassinger, is joined on this episode by Garnet Chan, the Bren Professor of Chemistry at Caltech, a member of the National Academy of Sciences, and among the most cited computational chemists in the world (34,000+ Google Scholar citations). Garnet is neither a quantum computing booster nor a dismissive skeptic. He's a theorist who works at the exact boundary between what classical algorithms can and cannot do — and who keeps finding that boundary further out than the quantum computing community has claimed. The FeMo-cofactor has been a flagship quantum computing use case for nearly a decade: a catalytic core of the enzyme that fixes atmospheric nitrogen into ammonia, and a molecule widely described as "beyond classical reach." Chan's January 2026 paper challenges that framing directly. This conversation explains what was actually solved, what wasn't, and what it would genuinely take for quantum computers to contribute to the chemistry of nitrogen fixation. This episode is for researchers, engineers, and informed observers who want an honest, technically grounded view of where quantum computers genuinely help in chemistry — and where classical methods are more capable than the field has admitted. What You'll LearnWhy the FeMo-cofactor became one of the quantum computing community's favorite benchmark — and why the framing around energy savings from nitrogen fixation is less accurate than it soundsWhat "chemical accuracy" (~1 kcal/mol) actually means as a precision target, and why hitting it classically undermines a decade of quantum resource estimatesWhy real chemical systems are only "slightly entangled" — and what that means for the general argument that quantum computers are the natural tool for quantum chemistryThe difference between a problem being hard and a problem being exponentially hard — and why that distinction matters enormously for quantum advantage claimsWhere the genuine classical wall might be: bridging 15 orders of magnitude in timescale to simulate an enzyme's full catalytic mechanism — and whether quantum computers have anything to say about thatWhy Chan wrote a public blog post explaining his own paper — and what that reveals about the state of discourse in quantum chemistry and the quantum computing industryThe broader impact of quantum information science on chemistry — beyond hardware, the conceptual tools of quantum information have genuinely reshaped how chemists think about many-body statesWhat Chan is actually working toward: a full computational understanding of the nitrogenase reaction mechanism, using machine learning to bridge timescales classically — a decade-long journey he finds genuinely excitingResources & LinksThe Central Paper & CommentaryZhai et al.

  • Quantum Open Source with Will Zeng and Ziyaad Bhorat

    Quantum Open Source with Will Zeng and Ziyaad Bhorat
    Apr 17 2026
    Quantum Open Source with Will Zeng and Ziyaad BhoratIn this special live-streamed discussion, Will Zeng, co-founder of the Unitary Foundation, and Ziyaad Bhorat, VP at the Mozilla Foundation, join host Sebastian Hassinger to unpack their co-authored white paper, The Open Foundation Quantum Technology Needs. The paper argues that open source quantum software is structurally underfunded — too applied for academic grants, too public-good for venture capital — and that philanthropic organizations need to step in before the window closes.This conversation arrives at a pivotal moment. Google recently published a paper showing Shor's algorithm could break ECDLP-256 with roughly 500,000 physical qubits — a 20x improvement over prior estimates — while Oratomic launched claiming 10,000 reconfigurable atomic qubits may be sufficient for cryptographically relevant computation. The timelines are compressing. The question is whether the software ecosystem can keep pace with the hardware.The video of our conversation can be viewed on YouTube.What you'll learnWhy open source quantum software falls into a structural funding gap between academic grants and venture capital — and what that means for the field's trajectoryHow Mozilla Foundation evaluates emerging technology fields for philanthropic intervention, and what specifically convinced them quantum was ripe for engagementWhat Google's 20x efficiency gain for Shor's algorithm and the Oratomic launch mean for Q-Day timelines and post-quantum migration urgencyWhy the "quantum Linux" analogy is useful but incomplete — and what the real risk is (fragmentation, not monopoly)How Unitary Foundation's microgrant program ($4,000, six months) has become a faster on-ramp to quantum careers than traditional academic pathwaysWhat PyMatching, PyZX, and other microgrant-funded projects reveal about the scalability of small open source investmentsWhy open source benchmarking through Metriq Gym matters — and why vendor-driven benchmarks can't fill this roleHow the Qiskit team reductions at IBM illustrate the fragility of corporate-backed open source in quantumWhat specific policy asks the quantum open source community has for the NQI reauthorizationThe von Neumann vs. ENIAC lesson: why openness wins over secrecy in building transformative computing platformsResources & linksThe Open Foundation Quantum Technology Needs — The white paper by Zeng, Castanon, and Bhorat (March 2026) that anchors this conversationUnitary Foundation — 501(c)(3) non-profit building, governing, and sustaining open source quantum software since 2018 Mozilla Foundation — Non-profit championing open source and internet health, supporting Unitary Foundation's quantum workMitiq — Open source toolkit for quantum error mitigationMetriq — Community-driven quantum benchmarking platform Metriq Gym — Open source benchmarking suite for quantum computers Unitary Compiler Collection (UCC) — Quantum circuit compilation toolsQuTiP — Quantum Toolbox in Python, stewarded by Unitary FoundationPyMatching — Open source decoder for quantum error correction, originally funded by a UF microgrant PyZX — ZX-calculus library for quantum circuit optimization, also originating from UF support Unitary Hack — Annual bug bounty hackathon connecting open source quantum projects with global contributors CSIS Commission on U.S. Quantum Leadership — Warning on quantum decryption surprise referenced in the white paperWill Zeng — President and co-founder of Unitary Foundation; Partner at Quantonation; DPhil in Quantum Information, University of OxfordZiyaad Bhorat — VP of Imagination and Strategic Growth, Mozilla Foundation; PhD in Political Science, UCLAKey quotes"Do we want a future where quantum computers are developed by secret government contractors with specialized PhDs who have top secret security clearances? Or do we want a future where quantum computers are built in the private sector, competing to provide economic value to everyone around the world?" — Will Zeng"Do not be afraid to experiment. We're doing ourselves a disservice to be slow, especially in a space that really warrants experimentation." — Ziyaad Bhorat, on his message to philanthropic colleagues"There's billions of people on the planet who want to do exciting and interesting things. Building quantum technology is one of those. If you have enough motivation, you just need to provide some on-ramps." — Will Zeng"We should put forward an affirmative vision of what that future should look like and drive towards it — because otherwise it will be built in secret." — Ziyaad Bhorat"The US spends 30, 35 billion on potato chips every year. There's a lot of room to grow." — Will Zeng, on the scale of quantum investment relative to what's neededRelated episodesEp 19: Quantum Error Mitigation using Mitiq with Misty Wahl — Deep dive into Mitiq, one of Unitary Foundation's flagship open source projects discussed in this ...
