Periodic Reporting for period 1 - HyQuIP (Hybrid Quantum Integrated Photonics)

Okres sprawozdawczy: 2017-03-01 do 2019-02-28

Photons are ideal carriers of quantum information, as demonstrated in long distance quantum cryptography experiments. Schemes for quantum information processing based on photons have been proposed over the past 10 years, but implementation has progressed slowly. The reason is the lack of scalability of current approaches. In Hybrid Quantum Integrated Photonics (HyQuIP), we developed a new deterministic and scalable quantum integrated toolbox to generate, manipulate, and detect photons all on-a-chip, thus aiming to remove the bottlenecks currently limiting scalability of quantum science experiments. By relying on CMOS compatible hybrid technology and innovative nanomanipulation techniques, important milestones for on-chip quantum computing were realized. HyQuIP aimed to position Europe at the forefront globally in quantum information science. Quantum photonic technologies, the field of research in HyQuIP, will have an impact on the economy and society through commercialization and the creation of secure quantum communication, quantum metrology and imaging, quantum networks and quantum computing. Moreover, HyQuIP delivered the possibility to manipulate and measure quantum states on a single chip which is bound to boost the development of quantum sensing schemes and make the vast potential power of quantum systems available to a wide range of applications. Interactions and entanglement can be studied in new conditions with complex quantum states generated and manipulated on-chip, which has not yet been feasible with the conventional table-top approach. From a technological point of view, new fabrication methods were presented, that combine semiconductor, superconductors, piezoelectric materials in new hybrid photonic platform, which are some of the requirements the quantum optics community is striving for to implement on-chip quantum computing.

HyQuIP is a multidisciplinary project that spanned several interconnected research areas including nanofabrication, quantum nano-optics, superconductors, and numerical modeling. Additionally, the work involved both academic and industrial institutions to provide the proper environment for the PI to carry the proposed research. The main results can be summarized as follows
- Realizing a hybrid quantum photonic circuits combining silicon photonics and IIIV quantum emitters
- Multiplexing several, deterministically integrated, quantum sources on a single chip.
- On-chip routing of on-demand single photons
- Realizing novel photonic circuits on piezoelectric materials, with deterministically integrated quantum sources
- Controlled integration of superconducting detectors.
- Realizing a fully integrated quantum transceiver, combining the source, the detector, and the waveguide channel.
In HyQuiP, we followed a diverse approach in disseminating the results as shown below

The realization of practical quantum technology will have profound implications for society, as it will require reconsidering how we share and secure information, it will open new possibilities in solving complex problems and will enable a new generation of sensing devices. Quantum technology is progressing towards ever more compact devices with an increasingly recognized potential for commercialization and the creation of value outside the academic environment. The HyQUIP project combined highly interdisciplinary areas to provide means for generation, manipulation and detection of light at the nano-scale. Moreover, the developed technologies in HyQUIP, integrating single-photon sources, low-loss waveguides, strain tuning of quantum sources, high-extinction filters and efficient single-photon detectors are highly sought after for implementations of quantum technologies. The high level of integration and straightforward replication (scalability) of all building blocks the makes them ideally suited for real-world applications of quantum information technologies. Due to the compact, monolithic nature of the integrated platform all components are highly reliable and extremely robust to external influences. These features will strongly benefit the transfer of knowledge and technology developed within the HyQuIP project from laboratories to industry
