Large-scale cluster states as a flexible resource for quantum information processing
Cíle projektu
Photonics platforms represent a promising option for quantum computation as they can be operated at room temperature, are comatible with existing photonic manufacturing processes and can be easily connected within a quantum information processing network when operated at telecom wavelengths. Photons are vulnerable to loss and interact weakly, but can be measured with high detection efficiency and large bandwidth and therefore are ideal for measurement-based quantum computation (MBQC) schemes. The continuous variable (CV) multi-photon implementation of MBQC is particularly advantageous for its scalability potential and the possibility to realize fault-tolerant architectures. We will build a stable, compact and low-noise demonstrator of Gaussian MBQC featuring a number of transformative enhancements as well as evolutionary improvements compared to existing demonstrators. The addition of non-Gaussian operations will enable studies of qualitatively different graph states and will be an important step towards universal and fault-tolerant quantum computing. A new dual-mode continuous-wave/pulsed laser and telecom-wavelength single-photon detectors will enable this. By making the demostrator cloud-accessible, remote users will be able to program, execute and characterize quantum transformations and circuits in the cluster state. Variable graph connectivity enabled by a controllable interferometer configuration will make it possible to explore optimized gate teleportation designs with reduced noise. An increased bandwith of the squeezing sources will allow extending the size of the time-multiplexed cluster state. Full benchmarking of the generated Gaussian and non-Gaussian cluster states and of the performed gates will be carried out, going beyond currently used nullifiers and standard process tomography techniques. These steps will allow us to demonstrate the first CV-MBQC based photonic platform able to approach the noisy intermediate-scale quantum technology territory.
