Researchers from the Department of Physics (D-PHYS), ETH Zurich and colleagues from the Technische Universität München have experimentally demonstrated a monolithic mode-locked semiconductor laser with a continuously and widely tunable repetition rate. This laser system could become highly relevant for applications in areas such as spectroscopy, sensing and communications.

A collaboration led by researchers from the Department of Physics (D-PHYS), ETH Zurich tested the first prototype of a new elementary particle detector for ultrafast, three-dimensional and high-resolution imaging in large scintillator volumes without segmentation. #physics #d_phys #ethzurich
ETH Zurich researchers achieved stable quantum gates using neutral-atom qubits, leveraging geometric phases to ensure resistance to experimental noise.
———
Quantum exchange or swap gates are an important part of quantum computers with a large number of qubits.
———
Researchers at ETH Zurich have developed a swap gate for qubits made of neutral atoms that is based on a particular physical effect: the state of the particles switches depending on the path they take and is independent of external disturbances.
———
These so-called geometric phases make the system much less susceptible to experimental noise or imperfections.

👉 Nonlinearity as a key to correcting quantum errors 💡
Researchers in the Department of Physics (D-PHYS), ETH Zurich group of Professor Jonathan Home developed a new method, dubbed nonlinear reservoir engineering, to improve how to correct errors in quantum computations.
You can find the scientific article titled “Stabilization of Cat-State Manifolds Using Nonlinear Reservoir Engineering” in *Physical Review X*.
A team led by researchers from the Department of Physics, ETH Zurich demonstrated a quantum walk frequency comb semiconductor laser at telecommunication wavelengths, drawing attention to a technology that may soon become highly relevant for AI data centres, LiDAR and metrology.
You can find the scientific article titled “A quantum walk comb source at telecommunication wavelengths” in *Nature Photonics*.
Six new professors are joining ETH Zurich, while six current faculty members have been promoted. Their fields range from particle physics and quantum physics to health economics, nanomaterials, computer science, environmental biochemistry, global security and urban policy.
These twelve professors were appointed by the ETH Board in its meeting on 4 and 5 March 2026 and upon application of Joël Mesot, President of ETH Zurich.

Researchers at ETH Zurich and the University of Basel switch a ferromagnet’s polarity with laser light, paving the way for light-controlled circuits.
——— • Researchers at ETH Zurich and the University of Basel have inverted the direction of the magnetic field of a ferromagnet – comparable to a compass needle – using a short laser pulse.
——— • The ferromagnet consisted of a special material made of twisted atomic layers and was based on topology, a particularly robust state of matter that is very resistant to change.
——— • In the future, laser pulses could be used in this way to create arbitrary and adaptable electronic circuits.
