Researchers from Princeton University have successfully shown that two quantum-computing components, known as silicon “spin” qubits, can communicate even when ordered relatively far apart on a computer chip. These futuristic computers will require tens of thousands of qubits that can communicate with each other to realize quantum computing’s promise. Researchers from Princeton University, however, allege that while today’s prototype quantum computers from Google, IBM, and other organizations hold tens of qubits produced from a technology involving superconducting circuits, many researchers see silicon-based qubits as more likely in the long run.
