This is your Quantum Computing 101 podcast.

Today the quantum world feels closer than ever, especially with yesterday’s headlines. The Nobel Prize in Physics just honored Michel Devoret, John Clarke, and John Martinis—the architects who proved quantum tunneling works not only in theoretical sandboxes, but on real chips, with groups of electrons punching through barriers almost magically, giving rise to the superconducting qubits on which much of our field relies. That’s not ancient history; it set the stage for everything happening now, from mobile phones to quantum computers humming in national labs.

I’m Leo, your guide to Quantum Computing 101, and I have a passion for where classical and quantum lines blur into something new. If you caught TIME’s announcement two days ago, you saw Quantum Brilliance’s ‘Quoll’ named one of 2025’s Best Inventions for bringing quantum power—inside a small, portable module—into the everyday working world. Even more intriguing, Oak Ridge National Lab just unveiled their first onsite quantum-classical cluster. This isn’t sci-fi; scientists there now run combinatorial optimization tasks at speeds impossible with classical chips alone.

But today’s true marvel is hybrid sequential quantum computing. Recently, Pranav Chandarana and colleagues published the first demonstration of a paradigm called HSQC—Hybrid Sequential Quantum Computing—tailored for combinatorial optimization. Picture this: first, a classical optimizer like simulated annealing rapidly scouts the problem landscape, identifying promising solution valleys. But classical methods easily get trapped in local minima, stuck like a hiker lost in fog. Quantum algorithms—specifically, bias-field digitized counterdiabatic quantum optimization—then step in, using quantum tunneling to pierce right through those energy barriers, revealing unexplored terrain where better answers lie. Finally, a third classical method polishes these quantum-enhanced candidates, diving toward the ground state with relentless precision.

I recently visited a superconducting quantum processor lab—imagine a room colder than deep space, filled with racks of tangled wires and glinting sapphire chips. The 156-qubit heavy-hex device buzzes quietly, each qubit a tiny world of probability, responding to pulses that coax them to shift and flip, sometimes tunneling through barriers in ways that would stun a classical engineer. When HSQC took on higher-order binary optimization in those conditions, it reached ground-state solutions hundreds of times faster than standalone classical algorithms. It’s like pairing a chess grandmaster with a prodigy who can see alternate dimensions of the game.

We’re seeing a future where hybrid quantum-classical clusters—and initiatives like the Quantum Brilliance Quoll—make these capabilities available in hospitals, stock exchanges, factories, even local governments chasing smarter resource allocation. Superconducting chips, photonic networks, trapped-ion clusters—each brings its own signature to the chorus. The classical and quantum realms intertwine, forming co-processors that will someday seem as ordinary as our GPUs.
