Percolation based architecture for cluster state quantum computation using photon-mediated entanglement between atomic memoriesQuantum PhysicsWe propose an on-chip scalable cluster-state quantum computing (QC) architecture comprising a two-dimensional array of atomic qubits and detectors, networked by photonic...
Single-photon-based quantum technologies significantly benefit from photonic integrated circuit (PIC) implementations, which leverage modern nanofabrication methods for the realization of complex quantum optical networks on a stable and scalable platform3. One of the key requirements for realizing the ...
Performing quantum computing tasks with higher dimensional states -- qudits -- has been proposed, yet a qudit-based PEA has not been realized. Using qudits can reduce the resources needed for achieving a given precision or success probability. Compared to other quantum computing hardware, photonic...
Scientists are looking for new, breakthrough solutions that can greatly advance computing and networking systems.
