Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer

Understand

Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature.

• However, no concrete architecture has been presented so far that exploits both the advantages of qubits encoded into states of light and the modern tools for their generation.
• Here we propose such a design for a scalable and fault-tolerant photonic quantum computer informed by the latest developments in theory and technology.
• Central to our architecture is the generation and manipulation of three-dimensional hybrid resource states comprising both bosonic qubits and squeezed vacuum states.
