Current obstacles

Scaling beyond 30 logical qubitsSept 2026 used distance-2 detection (no correction). Full correction needs distance 3+, lower error rates, and more atoms.
Atom loss during computationAtoms escape from traps at rates of ~1–5% per second. Loss correction mitigates this but trades it for higher error rates elsewhere.

Physics limits

Atom loading is slowLoading atoms into a tweezer array and holding them takes milliseconds. This sets the cycle time: at least one millisecond per quantum gate, about a thousand times slower than superconducting qubits.
Rydberg blockade range limits densityTo use Rydberg interactions, atoms must be far apart (10 micrometres) so only nearest neighbours interact. Closer packing works but makes gates slower and adds crosstalk.
Loss is fundamental to dynamic reconfigurationMoving atoms from one tweezer to another during computation can fail (atom escapes). The frequency of these escapes sets a bound on how often atoms can be rearranged.

How it works

4 parts

Tweezers

Laser grids hold atoms

Focused laser beams form a 3D grid of traps, each holding one neutral atom in vacuum. Atoms can be moved on demand during the computation.

Rydberg states

Excited atoms interact

Atoms excited to Rydberg states strongly interact with neighbours, allowing fast two-qubit gates.

Loss correction

Retry after escapes

Some atoms escape from traps; loss correction flags lost atoms and runs failed attempts again, trading error rates for higher success probability.

Readout

Fluorescence imaging

Atoms are excited to fluoresce and imaged with a camera, so the state of all qubits is read at once.
