Scientists are exploring a groundbreaking way to improve the clarity of electron microscope images by combining them with quantum computing technology. This approach could allow researchers to capture high-quality images using fewer electrons, which could reduce damage to delicate samples. Researchers from TU Wien have joined forces with teams from the University of Vienna, JKU Linz, and the University of Innsbruck to develop a new method that uses a quantum computer to extract more information from each electron.
The technique involves linking an electron microscope with a quantum computer that uses trapped ions. By creating a quantum entanglement between electrons and ions, researchers can store information about the electrons in the ions. This enables the combination of data from multiple electrons through carefully designed quantum operations. As a result, the signal strength can be improved using fewer electrons, which could lead to clearer images with less damage to the sample being studied.
The imaging process still relies on electrons to capture the image, but the quantum computer handles information that would typically be lost in traditional methods. The researchers have already validated the approach mathematically and are now working on implementing it in a real-world setting. This experimental work is being conducted at TU Wien's University Service Center for Transmission Electron Microscopy (USTEM).
The quantum computer used in this project was developed by Philipp Schindler's team at the University of Innsbruck. The research is supported by the Austrian Science Fund (FWF) through the Cluster of Excellence quantA and the Gordon and Betty Moore Foundation, which are funding efforts to advance quantum technologies and their applications in various scientific fields.
