Pasqal · neutral atoms · PLANNED (targeted availability for users 2028; 'apt for early FTQC') (2028) · 500 physical qubits · access: n/a
architecture: Rydberg tweezer array — alkali (Rb/Cs) · Open on the map

Register profile — the machine's variant of its architecture

qubit type: laser-trapped neutral atoms (species not stated for Centaurus; Pasqal's QPUs use rubidium)
gate mechanism: early fault-tolerant operation ('apt for early FTQC', Pasqal 2025 roadmap); gate mechanism not published
control: laser-trapped atoms, zero cryogenics; photonic integrated circuits to be added across the roadmap for control fidelity and scalability
control placement: optics (room temperature)
gate evidence: no published figure
flags: a target, not a device
