IBM Zurich Research Laboratory

The IBM Zurich Research Laboratory was established in 1956 as IBM's first research laboratory outside the United States, initially located in Zurich's Enge quarter before moving to Rüschlikon in 1962¹. It was founded to conduct fundamental research in physics and computer science, complementing IBM's other labs in Yorktown Heights and San Jose. The lab's early work focused on semiconductor physics and magnetic storage, laying the groundwork for later breakthroughs.

The laboratory is renowned for two Nobel Prize-winning discoveries. In 1986, Gerd Binnig and Heinrich Rohrer were awarded the Nobel Prize in Physics for inventing the scanning tunneling microscope (STM), which enabled atomic-scale imaging and manipulation². In 1987, Georg Bednorz and K. Alex Müller received the Nobel Prize in Physics for their discovery of high-temperature superconductivity in ceramic materials³. These achievements established the lab as a world leader in condensed matter physics.

Today, the lab focuses on a wide range of fields, including nanoscale science, quantum computing, artificial intelligence, and cloud security. Notable innovations include the development of the racetrack memory concept, which uses magnetic domain walls to store data, and contributions to IBM's quantum computing efforts, such as the design of superconducting qubits. The lab also hosts the IBM Research Quantum Network, collaborating with academic and industrial partners.

Beyond the headline discoveries, the lab has a rich history of lesser-known contributions. For instance, in the 1960s, researchers at the lab developed the first practical magnetic bubble memory, a non-volatile storage technology that was later commercialized but eventually superseded by other technologies. The lab also played a role in the development of the Josephson junction computer, an experimental high-speed computing technology that was ultimately abandoned. Additionally, the lab has a tradition of hosting visiting scientists and has been a training ground for many prominent physicists, including Nobel laureate J. Georg Bednorz, who spent his entire career there.

Scanning tunneling microscope (STM)

An instrument that images surfaces at the atomic level by measuring the tunneling current between a sharp tip and the sample.

High-temperature superconductivity

Superconductivity at temperatures above the boiling point of liquid nitrogen (77 K), first discovered in copper-oxide ceramics.

Racetrack memory
