Current Position & Biography
Mark Zhandry is an associate professor of computer science at Stanford University, a role corroborated by Stanford’s faculty directory. His personal biography also lists a part-time visiting faculty researcher appointment at Google Quantum AI. He works on cryptography and quantum computing. His published office is CoDa W210; Stanford’s campus map locates CoDa in Stanford, California. The United States field reflects this professional university base, not nationality or personal residence. His earlier roles at Princeton University and NTT Research are historical appointments rather than his current primary affiliation.
Notable Contributions
Zhandry authored Quantum Lightning Never Strikes the Same State Twice. The paper studies quantum states that remain resistant to duplication even when an adversary generates the state. It explores possible applications including decentralized cryptocurrency without a blockchain and random strings accompanied by evidence of entropy. Its construction relies on an assumed form of multi-collision resistance for polynomial systems. These are research proposals and conditional security results, not evidence that a practical cryptocurrency with these properties has been deployed.
Why Katharos.ai Is Following Them
Katharos.ai is following how quantum information changes the assumptions behind digital scarcity and verification. A proposed payment mechanism can be conceptually different from a conventional blockchain while still requiring careful scrutiny of its physical requirements and adversarial model. The useful question is not simply whether a design is described as quantum, but precisely what must be built and trusted for its security argument to apply.
Areas to Follow
Areas to follow include independent analysis of construction assumptions, the gap between abstract quantum operations and available hardware, and the distinction between a theorem, a prototype and an operational payment service. Reporting should separate potential applications from demonstrated capabilities. These are editorial priorities, not claims that Zhandry operates a token project or recommends any digital asset.
Reporting Scope
Current university rank is independently corroborated; the additional Google appointment is attributed to the personal biography. The technical section summarizes the cited 2017 paper rather than certifying the continuing security of every proposed instantiation. No investment recommendation or claim about present production readiness is implied. The portrait is used for factual identification of the researcher.

Limited editorial identification, not endorsement; no open license asserted. The original JPEG identifies PATRICIA ROSSI PHOTOGRAPHY as creator in EXIF, XMP and IPTC metadata, with an April 12, 2025 capture date and subsequent Lightroom, Photoshop and Evoto processing history. That metadata is retained without claiming the source photograph was unprocessed. No image-specific reuse grant or restriction was identified on the personal page. Public accessibility is not unrestricted permission; this modest complete-photo presentation is a bounded editorial identification use. The original file remains unchanged in the evidence package.
