   Fault-tolerant Quantum Computing with Photonics

   Presenter: Mercedes Gimeno-Segovia, PsiQuantum, United States

    Presentation Details

   Invited

   General-purpose fault-tolerant quantum computers will utilize millions of physical qubits, thus requiring an underlying qubit technology that can be manufactured at scale. Integrated silicon photonics is an intrinsically scalable and manufacturable platform where all necessary gates are available to manipulate qubits, encoded in photons, with very high fidelity and low noise. In this talk, we will discuss architectures for fault-tolerant quantum computing with photonics in the newly introduced fusion-based quantum computing paradigm. Fusion-based quantum computing presents a new framework for fault-tolerant quantum computation, focused on the efficient integration of quantum error correction and physical-level hardware operation. Its primitives, small, entangled resource states, and projective entangling gates make it particularly useful in an integrated photonics platform, since they can be implemented in with a modular hardware configuration, offering significant architectural simplifications and reducing requirements on physical level operations.Authors: Mercedes Gimeno-Segovia, PsiQuantum
