Shrinking qubits for quantum computing with atom-thin materials: Using 2D materials, researchers have built superconducting qubits that are a fraction of previous sizes, paving the way for smaller quantum computers.

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.
