  • #86: Millions of Qubits in a 6U Form Factor
    Jul 14 2026

    I spoke with Jason Lynch, CEO of Equal1, about the actual size of the Bell-1 silicon spin quantum computer, when we’ll see a breakthrough in qubit counts, quantum networking the devices together, shrinking the system from 22U to 6U, power consumption, democratization, and more.

  • #85: “We can solve problems 43 million times bigger than anyone else.”
    Jun 30 2026

    I spoke with Toby Cubitt, Co-Founder and CTO of Phasecraft about why we need algorithms when we don’t have hardware to run them on, a claim of 43,000,000X greater efficiency, the skillset needed to do what they do, quantum phase estimation (QPE) without controlled unitaries, the secret ingredient of their secret depth-reducing sauce, and more.

  • #84: How to Future-Proof "Quantum-Safe"
    May 12 2026

    I spoke with Eric Hay, Senior Vice President of Field Engineering at Quantum XChange, about single-use private keys, the prevention of retrieval after they’ve been used, secure key exchange, the architectural solution to the potential vulnerability in post-quantum cryptographic (PQC) protocols, the continued use of symmetric keys on the same channels on which they were exchanged, and more.
