The final QS-device, tested against a known benchmark

Set the system to model a complex spin-frustrated molecule (benzene, 6 photons) or spin lattice and to perform a quantum simulation with photonic states in order to benchmark the device. Physical insights and comparison with other calculations will allow to test the accuracy of the results.

Summary dissemination and communication activities

The dissemination and communication activities will be summarized and updated in view of the advancements of the progect WPs and results.

Proof-of-concept Quantum Simulations

Integrated laser-written waveguides structures (UROS) and fiber-network architectures (UNIVIE) will be used for QS experiments of initially 6 entangled photons for quantum transport experiments as well as the quantum simulation of small molecules (benzene). Further, the experiments will be extended to larger number of photons (8 and up to 16) for random walks in higher dimensional Hilbert space and Heisenberg 4x4 lattices. Results will serve as input for setting the integrated photonic architecture in T2.4.

Demonstrators, pilots, prototypes (1)

Fully functioning QS-prototype interfaced to the software

1. Testing the whole integrated system to verify the compatibility both in terms of input-output and single module functionalities. Develop an electronic board to drive the EIC wired Q-PIC. Input from specification of the analog circuit. Development of a software interface to allow an easy system control. 2. A first simulation, within a range of input parameters, allowing a software emulation of the QS, will be carried on. The results will be validated with respect to the software theoretical calculation. Important is the estimate of the reliability of the QS results with respect to the classical benchmark.
