Aquila
Aquila
Register profile — the machine's variant of its architecture
qubit type: ground-Rydberg analog qubit (not a hyperfine ground-state qubit)
gate mechanism: analog Hamiltonian simulation: a programmable Rydberg Ising Hamiltonian under global drive with local detuning; it does not run gate circuits
connectivity: reconfigurable 1-D/2-D tweezer register
control: SLM tweezers + AOD moves + Rydberg lasers
control placement: optics (room temperature)
readout: fluorescence imaging, destructive, ~0.5-1 ms
gate evidence: no published figure
flags: analogue operation only
