Phys.org  December 5, 2022 To understand the inner workings of quantum computing and enable supercomputing a team of researchers in the US (Iowa State University, University of Alabama at Birmingham, University of Wisconsin-Madison, Madison, Florida State University, Ames National Laboratory) built a Cryogenic Magneto-Terahertz Scanning Near-field Optical Microscope (cm-SNOM). It comprises three main equipment: i) a 5 T split pair magnetic cryostat with a custom made insert for mounting SNOM inside; ii) an atomic force microscope (AFM) unit that accepts ultrafast THz excitation and iii) a MHz repetition rate, femtosecond laser amplifier for high-field THz pulse generation and sensitive detection.
