Professor June-Koo Kevin Rhee's interview was reported in KBS News(Quantum Computing)
Professor June-Koo Kevin Rhee’s (Director of KAIST ITRC of Quantum Computing for AI center) interview with Quantum Computing was reported in KBS News. You can see the interview of Professor June-Koo Kevin Rhee in the full article below. ------------------------------------------------------------------------------------------------------------------------------------ [US•China Competition, Japan also chase... ‘Key of forth Industry’ Life and Death of Quantum Computer Development] [Anchor] In order to preoccupy the fourth industry, such as autonomous driving and artificial intelligence, countries around the world are putting their lives to the competition for quantum computer development. A quantum computer can complete operations that take 100 years for a supercomputer in hundreds of seconds. The United States and China are leading the way, and Japan is chasing fast, but Korea is still in early stages. Reporter Seoyoung Son covered it.   [Report] The world's first commercially available quantum computer that looks like a chandelier. Colorful pure gold parts are mounted inside the circular column. It works only at cryogenic temperatures, minus 273.15 degrees with zero electrical resistance. Unlike ordinary computers that operate on 'bit' units, which are combinations of zeros or ones, quantum computers use states of 0 and 1 that overlap or become entangled. Storage and processing capacity become up to trillions of times. It can complete operations that take 100 years for a today's most powerful supercomputer in hundreds of seconds. When the quantum computer is put into practical use, it is possible to process large amounts of data quickly, which can greatly develop the fourth industry such as autonomous driving. [Robert Sutor/IBM Quantum Vice President : “Computing much faster with a quantum computer can accelerate the benefits of AI”] In particular, the world's focus on quantum computers is their ability to solve complex cryptosystems. US and China are also fiercely competing for a security using quantum computers. Japan, which has been intensively investing since the '80s, is also closely following. [June-Koo Kevin Rhee/Professor of KAIST School of Electrical Engineering : The fact that it can break the cryptosystem has led to a lot of investment in quantum computers, while these concerns have led to the development of new cryptosystems.“] However, Korea still lags far behind Japan in new concept computing technologies such as quantum computers. The quantum industry market continues to grow, and by 2035 it is expected to reach 400 trillion won, close to the current semiconductor market. This is Seoyoung Son from KBS News.

Ph.D student Woo Chan Lee(Advised by Seung-Hyup Yoo) won the Best Student Paper Award 1st Prize at the OSA Advanced Photonics Congress 2019
Ph.D student Woo Chan Lee(Advisor:Seung Hyup Yoo) won the Best Student Paper Award 1st Prize at the OSA Advanced Photonics Congress 2019 in San Francisco, USA. The OSA Advanced Photonics Congress is the conference which is organized by OSA to present various researches on photonic devices. In this research, they fabricated an OLED that emits near-infrared light using a down-conversion method. Near-infrared OLED has been very difficult to achieve high efficiency and stability, mainly due to material limitations. In this research, they used a method that combines a phosphor that converts orange light into near infrared and an orange OLED that has a high efficiency and stability by using a down-conversion. Through optical analysis and optimization at the down-conversion process, they finally implemented a near-infrared OLED with a near-infrared external quantum efficiency of about 14%. The developed light source is expected to be used for wearable healthcare, because it has the advantages of OLED flexibility and near-infrared rays with various applications. Congratulations! Conference OSA Advanced Photonics Congress 2019 Date 2019.07.29~2019.08.01 Location Hyatt Regency San Francisco Airport, San Francisco, California, USA Winner Ph. D Student Woo Chan Lee (Advisor: Seung Hyup Yoo) Awards Best Student Paper Award 1st Prize Paper Down-conversion Based Near-infrared Organic Light-emitting Diodes with High Efficiency and Low Roll-off

Professor Jae-Woong Jeong's research team developed a wireless control technology of the neural network in the brain using a smartphone
Through cooperative research of Professor Jae-Woong Jeong in our department and Michael Bruchas in University of Washington, their research team developed a wireless device for brain implantation which can control neural network precisely. The precise control is enabled by drug infusion and light emission to particular areas of the brain. This technology is expected to be applied not only to the development of new drugs which needs animal testing but also to the treatment of a brain disorder such as Parkinson's. The research, for which Raza Qazi (first author of the paper), Choong Yeon Kim, and Sang Hyuk Byun developed the device and in which neural science research team from University of Washington collaborated, was published in Nature Biomedical Engineering on 6th, August (The title of the paper: Wireless optofluidic brain probes for chronic neuropharmacology and photostimulation). By optogenetics and neuropharmacology, target neurons or neural circuits can be controlled without affecting other neural circuits. Because it has a much finer spatiotemporal resolution than conventional electrostimulation, this method is recently focused on the purpose of brain research and treatment of brain disorders. However, current devices which are mostly used for brain research are some problems; damage to brain structure and their inability to control brain circuits precisely and be designed as one multifunctional probe. Also, there is a gap between soft brain structure and hard materials like silica and metal which are constitutive of the devices. With these reasons, those devices will aggravate infections so they are not appropriate to be implanted for a long time. The research team made tiny flexible probes by combining microfluidic probes and micro LEDs and fused the probes with small control circuits based on Bluetooth and replaceable drug cartridges. Thus, the team invented the neural-implantable device with a smartphone Bluetooth control of LED and drug infusion. Especially, the drug cartridges were designed to imitate LEGO so new cartridges can be connected to the device to provide drugs repetitively for a long time. Research team implanted the device on a target neural circuit of a mouse and combined cartridges with dopamine activator and inhibitor. Finally, the team succeeded in activating and inhibiting the behavior of the mouse by using the smartphone application. In addition, the research team injected light-sensitive protein into the brain of a mouse to stimulate place preference. The team made the mouse prefer particular place by turning on the micro-LED when the mouse moved to the place. In contrast, the team successfully deleted place preference of the mouse using drugs. Professor Jae-Woong Jeong said, "nerve control using light and drug is more exquisite and this makes it possible to control the brain without side effects. The invented device needs the easy smartphone operation to control specific brain circuits using light and drugs repetitively and continually. Therefore, the device will be adapted to studies of brain functions and treatments of brain disorders." The research team is studying to improve the device to apply this technology to human by implanting the device in the human skull completely and perpetually.   Figure 1.
