Researchers build largest quantum computer with 6100 qubits

Researchers have created a device with 6100 qubits, the largest collection ever assembled, marking a significant step towards building the most advanced quantum computer. This new device uses ultracold caesium atoms controlled by lasers, arranged in a grid. The qubits have been optimized for computational stability and accuracy, with tests conducted on qubit mobility within the array. The achievement demonstrates the scalability of neutral atom quantum computers. While further testing is needed, the team aims to scale the machine to a million qubits within a decade.
