aiqbench analysis
Researchers at the University of Stuttgart have successfully executed Grover's search algorithm on an integrated silicon photonic chip using up to four qubits via measurement-based quantum computing. This demonstration validates reconfigurable MBQC protocols on a scalable SOI platform, overcoming previous limitations regarding direct photon-photon interactions without requiring new fabrication technologies. The achievement establishes a foundational step toward larger-scale entangled resource states necessary for practical quantum processors.
Photonic Chip Runs Grover’s Search With Four Qubits
Researchers demonstrated measurement-based quantum computing on an integrated silicon photonic chip, generating up to four qubits.
Researchers at the University of Stuttgart have demonstrated measurement-based quantum computing on a silicon photonic chip, a significant step toward scalable quantum processors. The team generated entangled photonic states with up to four qubits and attained fidelities of 0.89 and 0.76 for four-photon star and linear graph states, respectively. These resource states enabled the implementation of both single- and two-qubit gates, as well as the successful execution of Grover’s search algorithm and the Deutsch, Jozsa algorithm. These results establish the feasibility of…
