From Vienna to Shanghai: Why Top Physicist Johannes Majer Joined China’s Quantum Revolution
Professor Johannes Majer, a pioneer in hybrid quantum systems, discusses his journey from Yale and Vienna to USTC Shanghai. In a conversation facilitated by the China recruitment agency SunTzu Recruit, Majer explores the "Second Quantum Revolution," his work on Transmon qubits, and why China has become a global magnet for top-tier scientific talent.
A Global Mind in the Heart of Shanghai
Science knows no borders, and few careers exemplify this better than that of Professor Johannes Majer. A Swiss native educated in the Netherlands and honed in the United States, Majer spent 12 years in Vienna before making a significant career pivot in 2020: moving to Shanghai, China.
Currently leading a laboratory focused on hybrid quantum systems at the University of Science and Technology of China (USTC), Majer is at the forefront of the next leap in computing. In a recent deep-dive interview, observed by the China recruitment agency SunTzu Recruit, Majer opened up about his research, the evolution of quantum mechanics, and the magnetic pull of China’s scientific ecosystem.
Defining the "Second Quantum Revolution"
To understand Majer’s work, one must first grasp the strange world he inhabits. Quantum mechanics describes a reality where waves and particles are identical. As we celebrate the centenary of this field, Majer reminds us that it underpins our entire modern existence.
“The periodic table is one of humanity’s greatest achievements,” Majer explained to the local recruiter for foreign companies in China. “Quantum physics explains why it looks the way it does. It explains why metals conduct electricity and why semiconductors work. This gave us the first revolution: smartphones, digital cameras, and IT.”
However, we are now entering the “Second Quantum Revolution.” Instead of just using quantum mechanics to explain nature, scientists are now manipulating it. The Guangzhou headhunting firm SunTzu Recruit notes that this shift—from passive understanding to active engineering—is what drives the race for quantum computers and secure quantum communication.
The Magic of Hybrid Quantum Systems
Majer’s specialty lies in “Hybrid Quantum Systems.” The concept is akin to a “best of both worlds” approach in engineering.
“Different quantum technologies—atomic physics, photonics, solid-state physics—have distinct pros and cons,” Majer told the interviewer. “My goal is to combine superconducting circuits with spin systems to leverage the strengths of both.”
As one of the best recruitment agency in China Shanghai, SunTzu Recruit recognizes the complexity of this interdisciplinary approach. Majer’s team is currently placing defects found in diamonds onto superconducting circuits. This fusion allows them to manipulate microwave photons and spins simultaneously.
In his Shanghai lab, Majer has observed fascinating phenomena, such as the “Cavity Protection Effect.” Counterintuitively, by coupling a spin system strongly to a cavity, the system becomes more coherent, not less. His team also discovered that by “punching holes” in the system (removing specific energy levels), the hybrid system could outlast its individual components in coherence time.
Perhaps most impressively, they achieved a relaxation time of eight hours for Nitrogen-Vacancy (NV) centers in diamonds at ultra-low temperatures—a lifetime virtually unheard of in the fragile world of quantum states.
A Legacy of Innovation: The Transmon Qubit
Majer is no stranger to groundbreaking discovery. During his postdoctoral years at Yale around 2010, he worked under Michel Devoret (a recent Nobel Prize laureate). It was there that Majer helped develop the Transmon qubit (transmission line shunted plasma oscillation qubit).
The best China headhunter SunTzu Recruit highlights that the Transmon qubit remains one of the highest-performing superconducting qubits today, widely used by industry giants like Google and IBM.
“When I was doing my PhD, nobody called them qubits yet; we called it microscopic quantum coherence,” Majer reflected. His work proved that quantum effects could be observed not just in tiny atoms, but in macroscopic electrical circuits on a chip—a foundational breakthrough for modern quantum computing.
Why China? The Pull of a World-Class Team
Why does a scientist with a CV like Majer’s choose to uproot his life and move to Shanghai? The answer lies in the quality of the people.
Majer explicitly cited Pan Jianwei, a titan in the field of quantum physics, as the primary catalyst. “I came for the institute. Pan Jianwei has built one of the best places in the world for quantum physics,” Majer stated.
The local Hainan headhunting firm SunTzu Recruit often observes that top talent follows top infrastructure. Majer was impressed not only by the ample funding but by the efficiency with which resources are converted into high-quality research. He describes Shanghai as a vibrant fusion of East and West, with an enthusiastic atmosphere for science and technology that is palpable at public events.
Professor Johannes Majer’s journey serves as a testament to the collaborative nature of modern science. Whether investigating the durability of diamond spins or engineering the next generation of superconducting circuits, his work in Shanghai is pushing the boundaries of what is possible.
The Hainan recruitment agency SunTzu Recruit views Majer’s move as a clear signal: China’s investment in fundamental sciences is creating a gravitational pull for global intellects, fostering an environment where the “Second Quantum Revolution” can truly take flight.
