Quantum Information Research Center (QIC)

Foundation

October 1st, 2020
QIC was founded as a global research center within the Institute of Advanced Sciences (IAS) ofYokohama National University.

VisionQIC is an environment where researchers in quantum information and related fields can gather,exchange information, create ideas on a day-to-day basis, and persistently launch high-value joint
research projects. We aim to promote practical research and to build a reputation for carrying out
world-class, large-scale research projects by participating as a core organization in national
projects and joint international projects.

TeamThe QIC Team is made up of professors/researchers of IAS and the Graduate School ofEngineering of Yokohama National University. In addition, there are several visiting
professors/researchers from other universities and National institutes who have joined QIC for
project collaboration. The QIC team brings quantum information to the level together with thecooperation of students.

Moonshot R&D

Goal 6 (=12 Projects)

fault-tolerant universal quantum computer

The Moonshot Researchand Development Programis a large-scale national
projectthatpromoteschallenging R&D projects
with the aim of resolving
difficult societal issues
while bringing together thewisdom of researchers
from all over the world. TheCabinet Office has set nine
ambitious goals to beachieved by 2050, and sixof them are handled by JST.

2030

• Development of NISQ computers of a certain scale• Effectiveness demonstration of quantum error correction

2040• Demonstration of distributed NISQ computers• Calculation of useful tasks under quantum error correction

2050• Realization of fault-tolerant universal computers

QuINT Milestones

2023
QuINT, proposed by Hideo

Goal 6 Milestones

20252030• Realize a hybrid quantum interface by developing technologies such as
optimal quantum light sources and quantum media conversion• Hybrid quantum interface that fuses diamond quantum memory andoptomechanical crystals, enabling a quantum connection between
quantum memories• Build the foundation of the quantum repeater network

Development of Quantum Interfaces for
Building Quantum Computer Networks
MissionDevelop a quantum interface technology that connects:
1. a microwave photon to a quantum memory
2. a quantum memory to a communication photon➔ Integrate these two technologies to create a quantum interface technology between computing
qubits and communication photons.

R&D for Construction of a Global Quantum Crypto Network
Global Quantum
Cryptography
Network
The Ministry of Internal
Affairs andCommunications of Japan
has set the goal of
constructing a global
quantum cryptography intheir Quantum
Technology Innovation
Policy.
The development has beenclassified into 4 categories.

QuREP is placed undercategory 3 and isresponsible for the total
scope of this category.

3. Quantum repeaterA) Quantum memory optical linkB) Quantum relay basis technologies

QuREP aims to create longer distance quantum cryptography and a more secure
repeating of encryption keys in terrestrial systems when compared to that of trusted
nodes.
