Phys.org  February 24, 2022 A team of researchers in the US (MIT, Columbia University, University of Chicago, Northwestern University) focused on a group of molecules with a central chromium atom surrounded by four hydrocarbon molecules to demonstrate how a particular molecular family of qubits can be finely tuned over a broad spectrum. They used synthetic chemistry to modify the physics of the qubits. Using the ligand field strength, they demonstrated remarkable fine tuning and showed that the ligand field strengths are adjustable over a relatively broad spectrum, and that it also controls the molecule’s electronic properties. The light emitted by […]
