Description
A large team reports lab work from 2026 on quantum bits that move inside silicon. The bits are single electron spins carried in small moving traps. Moving bits let a chip change its links during a run and group tasks by zone.
The team brings two spins toward each other and runs a two-bit gate on them while they move. Shifting each spin by a short span gave a gate score near ninety-nine percent. They also sent a quantum state between bits set farther apart, with a lower score. The result points toward large chips where moving bits handle links and gates.
