Canadian startup Xanadu has built a modular photonic quantum computer called Aurora that can be easily scaled up.
Aurora uses photonic qubits encoded in light, differentiating it from superconducting circuit-based quantum computers by Google and IBM.
The modular design of Aurora consists of four units installed in server racks, allowing for scalability by networking multiple units together.
Xanadu's progress is considered promising, although they currently have fewer qubits compared to competitors, but photonic quantum computers offer advantages such as resistance to environmental noise and ease of networking.
