• Abstract: We develop an architecture for measurement-based quantum computing using photonic quantum emitters. The architecture exploits spin-photon entanglement as resource states and standard Bell measurements of photons for fusing them into a large spin-qubit cluster state. The scheme is tailored to emitters with limited memory capabilities since it only uses an initial non-adaptive (ballistic) fusion process to construct a fully percolated graph state of multiple emitters. By exploring various geometrical constructions for fusing entangled photons from deterministic emitters, we improve the photon loss tolerance significantly compared to similar all-photonic schemes.

• Tailoring fusion-based photonic quantum computing schemes to quantum emitters [0.0]
  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.

• Deterministic generation of concatenated graph codes from quantum emitters [0.0]
  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.

  We propose fault-tolerant architectures based on performing projective measurements on constant-sized, entangled resource states. We present linear-optical constructions of the architectures, where the GHZ-state measurements are encoded to suppress the errors induced by photon loss. We believe this result shows a resource-efficient path to achieving photonic fault-tolerant quantum computing.

We realize the representation of photonic quantum states within truncated Fock spaces in SeQUeNCe. We observe varying fidelity with SPDC source mean photon number, and varying entanglement generation rate with both mean photon number and memory mode number.
