Quantum computing will be a world-changing technology with the potential to unlock powerful advances in medicine, energy, finance and beyond. At PsiQuantum, we’re focused on building the world’s first useful quantum computer. A useful quantum computer requires at least 1,000,000 qubits and error correction. We believe photonics is the only path to building a useful quantum computer. Our team at PsiQuantum is a mix of quantum physicists, semiconductor, systems, and software engineers, system architects and more. Error correction is at the centre of everything we do; and we focus on solving real-world problems. If you’re interested in joining our team, we are always open to hearing from exceptional people interested in working on one of the defining technologies of our lifetime.
