Shrinking qubits for quantum computing with atom-thin materials

ScienceDaily.com: Nanotechnology News - Wed, 12/01/2021 - 02:39
Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have taken advantage of atomically thin, 2D materials to construct the necessary capacitors for superconducting qubits. Their two-qubit chip is 1,000x smaller than those made with conventional fabrication techniques.
