Quantum record smashed as scientists build mammoth 6,000-qubit system — and it works at room temperature - Tristan Greene, Live Science

Scientists at Caltech have conducted a record-breaking experiment in which they synchronized 6,100 atoms in a quantum array. This research could lead to more robust, fault-tolerant quantum computers. In the experiment, they used paired neutral atoms as the quantum bits (qubits) in a system and held them in a state of “superposition” to conduct quantum computations. To achieve this, the scientists split a laser beam into 12,000 "laser tweezers" which together held the 6,100 qubits. As described in a new study published Sept. 24 in the journal Nature, the scientists not only set a new record for the number of atomic qubits placed in a single array — they also extended the length of "superposition" coherency.
