- Abstract summary: Fusion-based quantum computation is a promising quantum computing model where small-sized photonic resource states are simultaneously entangled and measured by fusion gates.
Here, we propose fusion-based architectures tailored to the capabilities and noise models in quantum emitters.
We show that high tolerance to dominant physical error mechanisms can be achieved, with fault-tolerance thresholds of 8% for photon loss, 4% for photon distinguishability between emitters, and spin noise thresholds well above memory-induced errors.

- Abstract: Fusion-based quantum computation is a promising quantum computing model where small-sized photonic resource states are simultaneously entangled and measured by fusion gates. Such operations can be readily implemented with scalable photonic hardware: resource states can be deterministically generated by quantum emitters and fusions require only shallow linear-optical circuits. Here, we propose fusion-based architectures tailored to the capabilities and noise models in quantum emitters. We show that high tolerance to dominant physical error mechanisms can be achieved, with fault-tolerance thresholds of 8% for photon loss, 4% for photon distinguishability between emitters, and spin noise thresholds well above memory-induced errors for typical spin-photon interfaces. Our construction and analysis provide guidelines for the development of photonic quantum hardware targeting fault-tolerant applications with quantum emitters.

Concatenation of a fault-tolerant construction with a code able to efficiently correct loss is a promising approach to achieve this.
We propose schemes for generatingd graph codes using multi-photon emission from two quantum emitters or a single quantum emitter coupled to a memory.
We show that these schemes enable fault-tolerant fusion-based quantum regimes in practical computation with high photon loss and standard fusion gates.

Fusion-based quantum computing (FBQC) is a model of universal quantum computation in which entangling measurements, called fusions, are performed on qubits of small constant-sized entangled resource states.
We introduce a stabilizer formalism for analyzing fault tolerance and computation in these schemes.
This framework naturally captures the error structure that arises in certain physical systems for quantum computing, such as photonics.

Sources of single photons that are highly indistinguishable and pure, that are either near-deterministic or heralded with high efficiency, have been elusive.
Here, we demonstrate on-chip photon sources that simultaneously meet each of these requirements.
