Scientists build modular quantum computers with LEGO-like qubits

Scientists have developed modular superconducting qubits that connect like LEGO bricks, enabling reconfigurable and scalable quantum computers. This breakthrough allows for high-fidelity entanglement and gate operations between qubits across separate modules, overcoming limitations of monolithic designs. The research demonstrates a promising path toward fault-tolerant quantum computing by enabling easier upgrades and error checking in future systems.
