🚀 Super excited to share a new paper and SDK from the BlueQubit team! We introduce Pauli Path Simulation (PPS) — an open-source, hardware-agnostic simulator capable of modeling utility-scale quantum circuits, including IBM’s 127-qubit Ising model. Advanced classical tools

The Quantum Insider’s Q2 2025 report highlights a turning point for the quantum industry, with $1.16B in private capital raised, landmark acquisitions, and technical milestones across the board. After a period of cautious optimism, investor sentiment appears to be shifting. Key

I am (slowly) re-reading the Tolkien legendarium (of which Lord of the Rings is a small part). The whole body of work is so incredible and there's nothing else like it... it dilutes other worlds of fiction. Wait - your story doesn't have a comprehensive history/mythology spanning

Exciting yet under-the-radar paper (arXiv:2506.10191) from Google Quantum AI on higher-order OTOCs (out-of-time-order correlators) -- a big leap toward practical (scientific) quantum advantage! 🚀 Using their Willow chip with ~100 qubits, they’ve shown remarkable result, yet it’s

Huge day for superconducting Quantum Computing 🏆 Clarke, Devoret & Martinis win the 2025 Physics Nobel for macroscopic quantum tunneling in Josephson (superconducting) circuits—the basis of superconducting qubits. Two are Google Quantum AI leaders (Devoret now, Martinis former).

Google has reached a remarkable milestone not seen since the heyday of Bell Labs: 5 of its current/former employees are science Nobel laureates. This remarkable concentration of talent signals a major shift: fundamental discoveries are no longer confined to the halls of academia
