The New Quantum Era - innovation in quantum computing, science and technology

Why This Episode Matters

Sabrina Maniscalco is one of the few people in quantum who has lived the full arc: two decades of academic work on open quantum systems and non-Markovian noise at Palermo, Turku, Edinburgh, and Helsinki, followed by founding Algorithmiq with three of her former researchers after an early Qiskit Camp. That trajectory matters now because Algorithmiq just had a landmark stretch — sole winner of the $2M Wellcome Leap Q4Bio prize for a quantum-enabled cancer drug discovery workflow, an €18M Series B, a global HQ move to Milan, and its Tensor Network Error Mitigation (TEM...

Why This Episode Matters

Firgun Ventures launched in late 2025 with a $70M first close anchored by the Qatar Investment Authority and a mandate that doesn't exist anywhere else in the market: lead Series A and B rounds in quantum scale-ups globally. Kris Naudts is a neuroscientist and former Culture Trip founder whose path to quantum runs through a near-fatal medical misdiagnosis. Zeynep Koruturk spent over a decade building the Goldman Sachs Tech Initiative and meeting more than a thousand founders. Both were early angels in what became Quantinuum.

Why This Episode Matters

Yuval has a rare profile in the quantum industry: an M.Sc. in physics from Tel Aviv University, an MBA from Kellogg, two decades as a CEO and CMO in deep tech before quantum, and now the commercial lead at QuEra — the company whose neutral-atom architecture is colocated with NVIDIA H100s inside Japan's ABCI-Q supercomputer and just demonstrated 96 logical qubits from 448 physical atoms in Nature. He also hosts The Superposition Guy's Podcast and has just published Quantum Bits, a comic-book guide to quantum computing.

This is a crossover conversation — Sebastian's book...

Fault Tolerance for Quantum Inputs and Outputs with Matthias Christandl

Why This Episode Matters

Most discussions of fault tolerance quietly assume a classical-in, classical-out picture: you feed in bits, the noisy quantum machine does its work, and a stable classical answer comes out the other side. Christandl — a mathematically trained quantum information theorist who also leads a Novo Nordisk Foundation–funded life sciences center — argues that this framing is too narrow for the era we are actually entering, where multi-core processors, networked QPUs, and quantum communication links all need to exchange quantum information betwee...

Philosophy of Physics Meets Quantum Engineering with Elise Crull

She was also one of the speakers on Helgoland in June 2025 for the centenary of quantum mechanics — opening, as Sebastian notes, by thanking the organizers for the courage to in...

Why This Episode Matters

Niels Bultink earned his PhD at QuTech under Leonardo DiCarlo, where he performed some of the first real-time feedback experiments on solid-state qubits — the foundational primitive behind quantum error correction. He spun Qblox out of TU Delft in 2018, and has grown it to roughly 140 people serving 150+ customers worldwide, mostly on revenue rather than venture capital, before raising a $26M Series A in 2024.

This conversation matters now because the goalposts for useful quantum computing have moved closer in the last 12 months. Recent estimates suggest breaking RSA may need ~10,000–100,000 qubits, not tens of mill...

Hardware-Faithful Digital Twins for Quantum Computing with Izhar Medalsy

Izhar Medalsy is not a career qubit theorist. His path runs from a physical chemistry PhD and an ETH Zurich postdoc in atomic force microscopy and ternary nanoscale logic, through productizing scientific instruments at Bruker, through building one of the fastest resin 3D printers on the market, into co-founding Quantum Elements in 2023 with Daniel Lidar (USC) and Amir Yacoby (Harvard). That arc — nanoscale measurement scientist turned deep-tech operator — shapes how he thinks about the simulation gap in quantum computing.

The conversation lands at a spec...

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

Ivan 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 ne...
