ICQNS 2023

IBS Conference on Quantum Nanoscience

October 10 - 13, 2023
​Ewha Womans University, Seoul, South Korea


Bringing the quantum nanoscience community together

There are many conferences that cover subfields of quantum nanoscience. However, as far as the organizers know, there is currently no conference that brings this broad community under one roof. With this conference, we are bringing together leading experts and young scientists from all around the globe to share recent advances and have in-depth discussions on these exciting research topics.


Besides the invited speakers listed below, we will have several contributed speakers in each session chosen from the submitted abstracts. You can also participate to the conference with a poster presentation or simply as a listener.

The local hosting will be provided by the Center for Quantum Nanoscience, which is located at Ewha Womans University in the heart of Seoul and is funded through the Institute for Basic Science. QNS has long-term expertise in investigating, assembling, and controlling quantum spin systems at surfaces. This relatively new topic in quantum nanoscience will be covered as one session in this conference.

Opening Session: Tutorial Talks

Andreas Heinrich, Center for Quantum Nanoscience (QNS), South Korea

Quantum-coherent nanoscience

Yonuk Chong, Sungkyunkwan University(SKKU), South Korea

Quantum-coherent science in Korea

Andrea Morello, University of New South Wales (UNSW), Australia:

Quantum Spins in Semiconductors

Poster Session

Session 1: Spin qubits in color centers and dopants

The spin of electrons and nuclei constitutes a highly coherent degree of freedom in the solid state. Color centers and dopants have the additional feature of being, in many ways, the solid-state equivalent of atomic systems. Their simplicity, robustness, and exquisite quantum coherence make them prime candidates for quantum computing, sensing, and communications.

David Awschalom, University of Chicago, USA:

Quantum Properties of Color Centers in Silicon Carbide

Andrea Morello, University of New South Wales (UNSW), Australia:

Quantum-Coherent Control of Dopants in Silicon

Session 2: Quantum nanophotonics

Single photons can be used to transport quantum information over long distances and therefore play an important role in quantum technology. Recently, important breakthroughs have been made in developing semiconductor-based single-photon sources.

Richard Warburton, University of Basel, Switzerland:

A low-noise quantum dot in an open microcavity

Rupert Huber, University of Regensburg, Germany:

Single molecules in slow motion videography

Session 3: Quantum control in molecular qubits

Molecules offer the combination of atomic scale structural control and tunability. Creating and manipulating quantum properties in molecules opens a pathway to designer quantum systems. Results on developing, understanding, and manipulating molecules will be presented.

Danna Freedman, Massachusetts Institute of Technology (MIT), USA:

Molecular Color Centers

Harry Anderson, University of Oxford, UK:

Coherent Effects in Porphyrin Molecular Wires and Nanorings

Session 4: Quantum surface science

Surfaces of materials offer the opportunity to use scanning probe techniques to measure their properties. This can be combined with atomic-scale manipulation to build structures with atomic-scale precision. Recently it has become possible to perform quantum-coherent manipulation of atoms on surfaces.

Yujeong Bae, Center for Quantum Nanoscience (QNS), South Korea:

Coherent control of spins on surfaces using scanning tunneling microscopy

Lisanne Sellies, University of Regensburg, Germany

Single-molecule electron-spin resonance with atomic force microscopy

Session 5: Quantum limits of mechanical motion

Mechanical degrees of freedom in the quantum regime provide new opportunities in sensing, computing, and fundamental tests of quantum mechanics. Via their versatile and strong coupling to many other quantum degrees of freedom (photons, spins, charges) while maintaining high-quality factors, they are now being used to augment quantum devices and test quantum mechanics at large length scales.

Ania Jayich, University of California, Santa Barbara (UCSB), USA:

Hybrid spin-mechanical systems in diamond for quantum information processing

Junho Suh, Pohang University of Science and Technology (POSTECH), Korea:

Mechanical oscillators toward quantum sensing

Session 6: Spin qubits in quantum dots

Semiconductor-based spin qubits offer a scalable platform for quantum information processing with long coherence times. Quantum gate fidelities have recently been improved beyond the threshold for fault-tolerant quantum computation.

Seigo Tarucha, RIKEN, Japan:

Designing and probing high-fidelity spin qubits and their environment

Guido Burkard, University of Konstanz, Germany:

Si qubit devices for fault tolerant quantum computation


International organizing committee



Ewha Womans University has a beautiful campus that is centrally located in the capital city of South Korea. It offers interesting architecture, green spaces and great facilities to hold a conference.

This is a very central location in Korea, only about 1 hour from the international airport in Incheon. Incheon airport has excellent connections to almost all parts of the world.

The weather in October is usually very nice with temperatures of 10°C-20°C, plenty of sunshine, and relatively low humidity.
