About QUP

Research Outlines

The International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (QUP) is a World Premier International Research Center (WPI) hosted by the High Energy Accelerator Research Organization (KEK), Japan. QUP aims to open a new frontier in fundamental physics by integrating state-of-the-art quantum measurement technologies with accelerator-based science.
While conventional particle physics has primarily advanced through higher collision energies, many of the most important mysteries in nature—such as dark matter, hidden sectors, and possible deviations from known physical laws—may lie in extremely weakly interacting phenomena. QUP introduces a complementary and transformative approach: exploring the weak-coupling frontier using ultra-sensitive quantum sensors, which we describe as new “Quantum Eyes” for observing the universe.
Leveraging KEK’s diverse beam facilities and advanced experimental infrastructure, QUP accelerates the full cycle of discovery—from concept and detector development to precision measurement and scientific breakthroughs. The Center promotes close integration of detector R&D, experimental physics, and advanced data analysis, enabling the exploration of previously inaccessible parameter spaces.
QUP is inherently international. English is the primary working language, and the Center collaborates closely with leading institutions worldwide. Through these global partnerships, QUP advances both fundamental science and technological innovation, while fostering the next generation of researchers in an open and interdisciplinary environment.
Beyond fundamental research, QUP actively seeks broader impact by extending advanced measurement and radiation-detection technologies to applications in environmental monitoring, industry, and society. By connecting scientific discovery with real-world needs, QUP aims to create lasting value for science and society alike.

About the logo

The logo consists of "QUP" surrounded by Ouroboros shaped like a face. Ouroboros is a serpent or dragon eating its own tail. It is often interpreted as a symbol of infinity, rebirth, and circulation.
Nobel Prize-winning physicist Glashow used the Ouroboros to describe the hierarchical structure of the universe. The universe is hierarchically structured at each scale: elementary particles, nuclei, atoms, molecules, stars, stellar systems, galaxies, galaxy clusters, and the universe. The universe has scales at the macroscopic extreme but is governed by the laws of elementary particles at the microscopic extreme. This resembles Ouroboros.In honor of this, we have incorporated the Ouroboros into our design.

Missions

QUP pursues a set of integrated scientific and technological missions aimed at advancing the frontiers of fundamental physics and quantum measurement:

1. Explore the weak-coupling frontier of nature
To search for previously undetected particles and interactions—including light dark matter, axions, and hidden sectors—by developing and deploying ultra-sensitive quantum measurement systems.

2. Establish “Quantum Eyes” for precision science
To create next-generation detector and measurement technologies based on superconducting sensors, quantum devices, semiconductor detectors, and advanced readout systems, enabling unprecedented sensitivity and precision.

3. Accelerate the full cycle from technology to discovery
To tightly integrate detector R&D, experimental implementation, and precision measurement using KEK’s unique accelerator and beam facilities, shortening the path from concept to scientific breakthrough.

4. Open new physics frontiers and deliver broader global impact
To investigate fundamental forces and gravity through innovative approaches, while fostering an interdisciplinary, international ecosystem. By nurturing future scientists and extending advanced sensing technologies to industrial and societal applications, we create long-term value beyond fundamental science.
