OIST Workshop "Quantum Technologies with Floating Charged Particles"

 Quantum Technologies with Floating Charged Particles 

         28-31 May 2024                        Okinawa, Japan 


The main subject of this workshop is categorized in the field of Quantum Information Science and Technology. The importance of developing quantum technologies for the future society is now recognized worldwide. One major goal of this field is clearly to realize a fault-tolerant quantum computer, but besides, quantum technologies are also believed to have potential for sensing and communication devices with unprecedent efficiency and precision.

Further exploration of novel physical systems interlinked with the advances in currently existing platforms would be a key towards dynamic development in this field. Tremendous progress has already been achieved in the system of trapped ions floating in vacuum. It is recognized that this system is one of the most promising candidates for building a universal quantum computer. Recently electrons trapped in the Paul and Penning traps have emerged as a promising candidate for quantum computing and simulations. Also, electrons floating above the surface of superfluid helium or solid neon recently had shown great potential for quantum technology. There are many striking similarities between these two systems. Like electrons and ions trapped in vacuum, such floating electrons exist in an extremely clean disorder-free environment, which ensures long coherence of their quantum states. Many experimental methods developed for trapped electrons and  ions can be potentially applied for floating electrons as well. Nevertheless, until recently the research in electrons on superfluid helium and solid neon has been developing independently from that of the trapped electrons and ions.

The aim of this workshop is to bridge, for the first time, the gap between these two exciting systems by bringing together leading experts representing both fields to discuss recent developments and to share ideas. It is intended to increase mutual awareness of the current trends in the research in these two systems and serve as a platform for future collaborations.
