Inside the neutral-atom approach
Registers, control and operations on encoded qubits. Four sourced contributions to read in sequence.

Benjamin Bloom
2021 · Controlling a nuclear-spin register
Bloom coauthored an experiment assembling and individually manipulating nuclear-spin qubits encoded in strontium-87 atoms. The team measured long coherence, including an echo coherence time of 42 ± 6 seconds. This is a memory-and-control result, not evidence by itself of universal fault-tolerant operation.
Benjamin J. Bloom was a coauthor of the strontium nuclear-spin experiment; coherence measurements are results of the full experimental team.

Mark Saffman
2022 · Multi-qubit operations on a neutral-atom computer
Saffman co-authored an experimental report on multi-qubit entanglement and algorithms using a neutral-atom quantum computer. The publication documents a move from individual atomic control toward coordinated operations on a programmable quantum processor.
Co-author of the collaborative 2022 neutral-atom experiment.

Dolev Bluvstein
2022 · Moving entangled atoms while retaining information
Bluvstein and collaborators demonstrated a processor in which entangled atoms are transported across two dimensions between layers of quantum operations. The experiment created programmable entangled states and code states, showing how physical motion can supply connectivity that a fixed qubit layout cannot easily provide.
Dolev Bluvstein was first author of the collaborative atom-transport processor experiment.

Mikhail D. Lukin
2023 · An encoded logical processor in atom arrays
Lukin coauthored a programmable neutral-atom processor experiment with encoded logical qubits. It combined reconfigurable connectivity, logical control and readout, and demonstrated improved performance using error detection. Particular experiments reached 48 logical qubits.
Coauthor of the logical-processor experiment; the stated capabilities refer to the team’s specific tested circuits.
