Quantum circuit optimization is cool, but I'm not convinced it's the primary bottleneck holding quantum computing back. We have been able to design and simulate quantum circuits for decades. IBM's Qiskit is just one example of the extensive software infrastructure already available. The much harder question is whether we can physically implement sufficiently large, fault-tolerant quantum computers, and whether their computational advantages will justify the enormous hardware and error-correction overhead. AI discovering more efficient circuits is a legitimate scientific achievement. But an algorithmic improvement, even by an order of magnitude, should not be confused with overcoming the fundamental physical and engineering limitations of quantum computing. I made this argument at the peak of the quantum-computing stock frenzy, and I stand by it today. There are far too many funding grifters and sensationalist headlines in this space. As impressive as these algorithmic breakthroughs may sound, they do little to resolve the fundamental challenges of scaling fault-tolerant quantum hardware. Quantum computing remains a long way from broad commercial viability. An order-of-magnitude improvement in circuit efficiency does not change that reality. For all the doomsday believers, let's panic over something else, like your SOXX selloff.
