PsiQuantum Targets Million Silicon Photonic Qubits by 2025 | NextBigFuture.com

Psiquantum has raised $215 million to develop what they claim will be the first useful general purpose quantum computer. They plan to make a million qubit quantum computer with error correction. Error correction is at the center of everything they do. They plan to reach the million error-corrected qubit level within 5 years. A million qubits will likely mean about 1000 error corrected qubits. PsiQuantum is based in Palo Alto and has been working on their designs for 5 years. Microsoft is one of the strategic backers of PsiQuantum. Google, Intel, IBM, Honeywell, D-Wave Systems, Rigetti and IonQ are all
