Quantum computers hold the potential to revolutionize the possibilities for solving difficult computational problems that would take classical computers many years to resolve. But for those computers to meet their potential, they need working quantum bits, or qubits. The hunt for a better qubit is a major project of researchers around the world, who are trying different materials and methods in their search.

In a study published in Progress in Quantum Electronics, researchers from the FAMU-FSU College of Engineering explored an unconventional and promising approach to building qubits by using quantum fluids and solids.

Their article examined how electrons trapped just above the surfaces of ultraclean quantum fluids and solids such as liquid helium and solid neon offer a combination of chip-level control and ultra-clean, defect-free environments, presenting a promising path toward scalable, high-fidelity qubits that could overcome key limitations of existing quantum technologies.
