Microsoft has been working on quantum computers for several years. Last year, Microsoft announced Azure Quantum, a full stack of open cloud ecosystems that will benefit quantum computing organizations. Microsoft has launched Quantum Networks, a global community of individuals and organizations that are working together to advance quantum computing. Microsoft Quantum Network members will work with Microsoft to learn, research and roll out quantum computing applications and hardware, and receive quantum development kits, important research and expert support, exclusive access to Azure services, and workshops on quantum programming and algorithm development.
Yesterday, the Telegraph reported that Microsoft’s venture capital firm M12 has invested in PsiQuantum, a start-up that aims to create the world’s first useful quantum computer using traditional silicon chips that process information electronically in addition to a single photon. This means that every component of a quantum computer is manufactured in the same factory and assembled on the same production line, just like your laptop or smartphone. PsiQuantum has assembled a team of more than 100 engineers with expertise in silicon manufacturing and error-correcting quantum computing.
It is worth noting that PsiQuantum’s approach differs from Microsoft’s efforts in topological qubits (Microsoft methods will enable error correction in the hardware through topological protection of local noise). PsiQuantum and Microsoft take different approaches to different engineering challenges, but the two companies share a vision for scalable, fault-tolerant quantum computers.
