About PsiQuantum Stock

PsiQuantum is developing a quantum computer using silicon photonics technology. In contrast to a matter-based quantum computing approach, PsiQuantum claims they benefit from over 50 years of research and trillions of dollars invested in silicon wafer technology. PsiQuantum claims to utilize photonic qubits in their computing solutions, and as such, they don't need to develop novel quantum technologies to create qubits from solid matter as their competitors do.

PsiQuantum was founded in 2016 and is headquartered in Palo Alto, California. Notable investors include BlackRock, Baillie Gifford, and Microsoft.
