The promotion committee, which consists ofexperts from related ministries and agencies andcontrols operations, is set up under the program
director (PD) at the Cabinet Oﬃce.
The management council is set up in the National
Institutes for Quantum Science and Technology(QST), the management entity, to support the PD’sdecisions. The council will decide the policies andgoals of the whole program, manage progress, andreview research subjects and harvesting strategies
based on the progress in order to ensure social
implementation.

Past Milestones and Anticipated Outcomes
Prototype of “Meister Data Generator” that automatically acquires high-quality big data to build the CPS-type laser material processing system, whichis the key to the world’s top productivity in processing in the manufacturing industry has been realized, and searching for autonomous machining
parameters by AI-driven decision has succeeded. As a result, we have set a goal of reducing the lead time required for selecting initial laser processing
conditions by 90%. We will accelerate and promote the building of partnerships toward the realization of network-type manufacturing.
We have succeeded in developing a highly light-resistant spatial light modulator device for social implementation of digital feedback light modulators,
and have made progress in mounting and demonstration experiments on laser processing machines installed at the University of Tokyo, Utsunomiya andHamamatsu bases. In addition, we conﬁrmed good benchmark results using industrial high-power lasers, and have built a base for promoting POC/pilot
projects for core companies in Japan and overseas by leveraging capacity of overseas research institutes.
The development of high-brightness photonic crystal surface-emitting lasers has been promoted, and brightness approaching 10 times that of conventional
semiconductor lasers was achieved by pulse operation. Also, we succeeded in constructing a lens-free, compact, high-resolution, high-precision LiDAR
system, etc., taking advantage of its high brightness. As a result, simpliﬁcation and sophistication of the system by the photonic crystal surface-emitting
laser has been clearly conﬁrmed. In the future, we will accelerate cooperation with user and manufacturing companies to promote smart mobility that
supports a safe and secure life and the ripple eﬀect of ultra-compact light sources for future smart processing.
In the development of the quantum cryptographic apparatus (BB84 protocol), the technology to achieve a 50% cost reduction was realized, and theparticipating organizations made it their intention to become entrepreneurs, therefore, we decided to aim to achieve the subsequent goals by individualcompanies and this SIP project itself was completed. For the quantum secure cloud technology development, we have completed the implementation andveriﬁcation of a system that can communicate GB-class genome analysis simulation data distributed and stored on a network with 3 bases in a 10km area
constructed in Sendai City at 50Mbps or higher. In the future, POC in ﬁnance and medical care ﬁelds will be promoted together with assumed users.
We have developed prototype software for the next-generation accelerator platform that utilizes Ising-type computers and NISQ (small and medium-scalequantum computers with errors) devices. As a result, it is expected that various social issues will be solved by the next-generation accelerator platform, suchas the solution of problems concerning optimal allocation of operators in a logistics warehouse and the application of quantum chemistry calculations. From
now on, we, looking ahead to the realization of Quantum Transformation (QX), will search for solutions to social issues to broadly contribute to Society 5.0.
