This is your Quantum Research Now podcast.

PsiQuantum just made headlines today after announcing it raised a staggering $1 billion to fast-track the construction of its utility-scale, photonics-based quantum computers, aiming for nothing less than a machine with over a million qubits. I’m Leo—the Learning Enhanced Operator—and you’re listening to Quantum Research Now. Today, we dive into what this jaw-dropping announcement really means for the quantum future that’s unfolding even as we speak.

Picture this: somewhere in Brisbane and Chicago, engineers, technicians, and physicists will soon be donning their cleanroom suits, prepping to build sites that might end up being as iconic for computing as Silicon Valley itself. PsiQuantum’s ultra-ambitious goal? A quantum machine powerful enough to tackle problems that would leave today’s most advanced supercomputers frozen, like chess grandmasters stuck after the first move.

Here’s why this matters: Traditional computers deal in bits—each one a clean-cut yes or no, a zero or a one. Quantum computers, on the other hand, tap qubits, which, thanks to the marvel called superposition, can be both zero and one at the same time. Imagine you’re at a crossroads: a classical bit picks left or right. A qubit? It goes left and right simultaneously, exploring every possible route at once. PsiQuantum, led by CEO Jeremy O’Brien, isn’t settling for incremental progress. They've thrown their weight fully behind photonics—using light, not electrons—to make qubits. Light barely interacts with its environment, making these qubits less prone to errors, which is the Achilles’ heel for every quantum engineer.

PsiQuantum’s confidence comes from manufacturing quantum photonic chips at scale, leveraging semiconductor fabs that already underpin modern computing. Recent experiments have shown that photonic approaches may be more easily scaled compared to their superconducting or ion trap rivals. The dream: a million-qubit, fault-tolerant quantum computer up and running by 2028. That would be like leaping from the Wright brothers’ Flyer I straight to a fleet of supersonic jets.

Consider the broader impact: With this funding—which involved titans like BlackRock, Temasek, and even Nvidia’s venture arm—PsiQuantum signals a global race is fully underway. IBM is racing toward a 20,000-operation-per-second quantum machine. Google and Quantinuum are making waves with their own error-correcting chips. It’s like the Space Race, but the destination is the next computational paradigm—a universe where problems in drug discovery, climate modeling, and cryptography could fold under quantum’s raw power.

For me, someone who can’t help but see quantum parallels in everyday life, PsiQuantum’s news feels like watching the first atoms of a new element condense out of the air: fragile, but teeming with potential. What happens as we layer classical and quantum architectures—melding the predictable with the possible? The future isn’t just coming; it’s being engineered, photon by photon, line by line, by teams who dare to think bigger.
