The Workshop on Quantum Computing and Quantum Information was held on June 3, 2019 at Tokyo, Japan, in conjunction with the 18 th International Conference on Unconventional Computation and Natural Computation (UCNC 2019).The Workshop was initiated by UCNC program committee members Shinnosuke Seki and Jarkko Kari, who suggested to the organizers that such a workshop could be beneficial.In the end of 2018, the program committee was assembled, and the call for papers was published subsequently.The topic area of the workshop was defined very broadly, and from the very beginning it was clear that the workshop should distinguish from the main event so that presentations including non-finished ideas should be also welcomed, and this was explicitly mentioned in the letter calling for papers.All submitted papers were peer-reviewed and the program committee accepted four contributions to be presented in the workshop.Unfortunately one manuscript was withdrawn by the authors, due to an unsuspected personal restriction for presenting the manuscript in the workshop.In addition to the contributing papers, the workshop included one plenary talk.Mika Hirvensalo gave a lecture on the role of interference in computing.

In this talk, I will discuss several schemes for all-optical quantum information processing that have been developed to overcome formidable limitations of the well-known approaches based on single-photon qubits and continuous-variable states.

Integrated photonics is a powerful platform for future quantum technology that encodes and processes information using single photons. In this talk I will describe an experimental realization of a quantum transistor, which mediates strong interactions between single photons using a single semiconductor spin qubits. These interactions are a key requirement for active quantum photonic devices. I will also present our recent work on hybrid integration of these devices with photonics, as well as applications in photonic quantum computing and topological photonics.
