Symposium on Physical Realization of Quantum Computing:
Superconducting and Molecular Qubits
31 Oct.-2 Nov. 2007, 2nd floor, Yutorito Higashi-Osaka

Proceedings submission page is now open [Deadline: April 30th, 2008]

The goal of this symposium is to understand molecular and superconducting qubits, and to overview their current status.

The symposium consists of 6 lectures focusing on the following topics:

Short contributions from participants are also welcome. If you are interested in giving a talk, please input the details of your talk from the registration site.


In the first lecture, Quantum Computation using NMR will be reviewed and the basic idea of quantum computation with the physical qubits will be introduced by Prof. Kondo. Although a liquid-state NMR quantum computer cannot be a practical one because of poor spin polarization, it can still be considered as a prototype of real quantum computers (hopefully realized in the future) and its understanding is a good start point for studying the other realizations.

One of the three lectures in the middle will feature electron and nuclear spins as qubits. The gyromagnetic ratio of an electron is about 1000 times larger than that of a nuclear spin. Thus, "Quantum Computation involving electron spins in addition to nuclear spins, ENDOR" may overcome the difficulty in "Quantum Computation using only nuclear spins, NMR", or poor spin polarization. Prof. Takui will give a lecture on this topic.

The other two lectures in the middle features on a qubit made of Josephson junctions, that is a most promising candidate for realizing quantum computers now. We invite two lectures who made a great advancement in this field. Dr. A. Niskanen made a switchable coupling between two qubits by introducing extra Josephson junctions. Dr. M. Sillanpää realized entangled two qubits those exist as far as 1.1 mm apart in space.

The last two lectures will focus on somewhat exotic resources, single-molecular magnets and Fullelene-C60, for quantum computers. Those may become a breakthrough for realizing a quantum computer. Profs. Kuroda and Wakabayashi are experts in molecular magnets and fullerene, respectively, and both of them are eager to take advantage of their experience to conduct quantum computer research.


The registration fee is free. We would like to ask you to register if you are willing to join us. When you are interested in giving a short talk, please enter the title and the abstract in the registration form before 26 October.

The banquet will be held on the 2nd evening (The cost may be around 3,000 yen).

This symposium is a part of the series of schools, workshops and conferences, being hosted by Open Research Center (Interdisciplinary Basic Study towards Realization of Quantum Computer) financially supported by Kinki University and MEXT.
