Dr. Ko-Cheng Fang, not just a technology executive, but a photonic quantum computing researcher who has developed vaccines for cancer and grown gemstones in labs as an inventor, scientist, and entrepreneur. His company LongServing Technology Co is the bold science of real world impact.
Who Is Dr. Ko-Cheng Fang?
Dr Ko-Cheng Fang is the founder, chairman and CEO of LongServing Technology Co, a Taipei-based company on the cutting edge of photonic quantum computing, AI robotics, biotechnology and synthetic jadeite manufacturing. LongServing was established in 2010 with a couple of core beliefs: science should address the problems that matter most irrespective of how long it will take for the solutions to come through.
Dr. Fang is recognized nationally and internationally for his work, having won a gold medal at the Geneva Invention Show as well as a silver medal at the Warsaw Invention Show. His work has helped with anti-terrorism technology for the USA Department of Homeland Security and advanced cancer research. He is crossing science and technology, even art too not unlike a modern-day Renaissance figure.
The Ideas That Started It All
The entrepreneurial insights for Dr. Fang began with two penetrating observations during the early days of personal computing.
The first: storage of data is brittle. Hardware crashes, reinstalls and system failures led to lost files. That became the heartbeat of what is known today as cloud computing, his solution, push data via the internet to a remote "virtual host"
The other: Really poor, irresponsible access control for computer systems. At the time Microsoft secured with a startup password that left machines exposed once powered up. Dr. Fang patented a program-level password lock, the technology that would later power virtually all of modern e-commerce, from Amazon to Taobao.
All patents were submitted and granted. The motivation for making them a reality inspired Dr. Fang to create LongServing Technology Co.
Redefining Computing With Photonic Technology
The most ambitious technical goal of Dr. Fang is the photonic quantum computing chip development, in his prediction, chips that he believes will totally take over conventional electronic semiconductors.
The issue with chips today is the physics: electrons being magnetic and quantum tunnelling are both signal degrading influences on which force miniaturisation. Photons are free of these disadvantages.
Dr. Fang came up with his own answer to that, an optical channel system where light-blocking walls and photonic gates take place of traditional copper wiring in the chips. That allows chip processes to go as low as 2nm, and below 1nm, areas of semiconductor territory where tried-and-true electronics begin to run into difficulty.
He holds 26 patents for his multi-bit photonic computing chips. His chips with picoscale circuit patterns are patented in 12 countries.
LongServing expects to start mass production of 50,000 wafers per month by releasing a 2 nm photonic CPU chip in 2025. Performance predicts: over 1,000 times that of conventional chips, with photonic channels and gates pushing computational capacity to ten thousand times current levels. Dr. Fang views this launch as the tipping point of where photonics officially supplants electronics in the basis of our computing.
Lab-Grown Jadeite: Where Science Meets the Luxury Market
Interestingly, as Dr. Fang was continuing some of his semiconductor work, he also noticed a major unexplored commercial opportunity in the global market for gemstones.
The surge of synthetic diamond in to mass production, slashing natural diamond prices by 40%, has manufactured it more attractive for consumers, particularly within the East Asian markets, opting for jadeite. The supply of natural jadeite is gradually stringent, and the price gap is growing wider. LongServing is placed to fill that gap.
This was the brand LongServing where it produced the world's first synthetic jadeite in mass production, boasting of ever more even colouring than the imperial green stone. Both Western and Eastern design sensibilities, and the company is developing the corresponding retail infrastructure: flagship stores planned for Shanghai, Tokyo, and Paris; runway partnerships with top models; advertisement films already made in Japanese, Korean, Chinese, And English.
Indeed the global jadeite market is still in its infancy as a commercial entity, yet itsAnnual transaction volumes are greater than USD 31 billion per annum. LongServing says the next two to three years is a particularly good opportunity for growth.
Biotechnology: Fighting Cancer and Viral Disease
Dr. Fang's biotech work is focused on two very pressing battle fields: cancer and antiviral ammunition.
LongServing has performed lab tests on not one but many cancer cell types in the oncology space and is taking steps towards animal testing. Instead of traditional chemotherapies, systemic treatments that wreak havoc on the body, the company is creating a targeted puncture injection technique focused on destroying cancer cells directly. They have recently made breakthroughs where 99% of liver and lung cancer cells were removed after testing.
As for antivirals, Dr. Fang has coupled traditional Chinese medicine with Western herbal research to find treatments against complex mutating viruses. He perceives that global mortality from influenza and viral outbreaks is continually underestimated, and thus considers antiviral drug development to represent one of the most significant areas of medical research where LongServing hopes to make a concrete impact.
On the Path to a Wall Street Listing
Dr. Fang and LongServing have long hoped to go public on Wall Street. The company, which is opening itself to foreign investment and plans unlisted stocks by the end of the year, has a full Wall Street listing in its sights.
The launch of 2nm photonic cips and continuous enhancement of the jadeite business are both convergent upon its core timeline.
Dr. Fang's view of LongServing's competitive position is direct: every innovation is developed and manufactured entirely in-house, without reliance on third parties. In a technology landscape where supply chain dependence is the norm, that independence is a deliberate and defining feature of how LongServing operates.

Final Thoughts
Dr. Ko-Cheng Fang is a rare kind of founder. His work simultaneously spans semiconductors, gemstones, cancer research, and antiviral development, fields that rarely appear under the same roof, let alone in the hands of one person. What connects them is a consistent approach: identify a problem that matters, engineer a solution from first principles, and protect it.
With the 2nm photonic chip launch on the horizon and LongServing's jadeite and biotech divisions both gaining momentum, 2025 stands to be a defining year, for Dr. Fang, and for the company he has spent fifteen years building.
