"scalable, captures atomic qubits in arrays using optical tweezers/ executes calculations via microwaves or laser pulses... long information retention... 50 physical qubits expandable to 500, with part of its capacity opened to external researchers to advance quantum software and error correction... ultimate objective of the initiative is to scale the platform to 10,000 physical qubits by March 2031 to establish a fault-tolerant, high-performance quantum computing infrastructure"
