"precisely observe/ manipulate quantum particles... consistent patterns emerge as number of qubits increase...  particle flow between 2 groups of qubits with different magnetic properties: (1) all qubits pointed downward, (2) half pointed up, half down... typicality: average spin polarisation, a macroscopic quantity, not the details of individual qubits or how prepared... larger systems showed more stable particle flow with fewer fluctuations, matching theoretical predictions about quantum behavior at larger scales"
