Quantum Computing

This cover image, related to article number 2300457 by Selçuk Çakmak and co-workers, illustrates the layers of a soft-core processor to execute RISC (reduced instruction set computer)-V instruction set architecture (RISC-V assembly code) on a quantum processing unit (QPU) based on superconducting qubits. The soft-core processor circuit layer represents a quantum circuit that realizes the example code on the QPU. As a result, the quantum computer (QC) writes the message on the QC terminal screen.
