Annealing vs Neutral Atom: Technology Tradeoffs

Annealing (used by D-Wave Advantage2)
Advantage
Very large qubit counts (5000+ physical qubits), fast sampling times (~microseconds per anneal), and a well-developed software ecosystem (D-Wave Ocean SDK) optimized for combinatorial optimization problems in logistics, finance, and scheduling.
Challenge
Limited connectivity between qubits requires problem embedding that can consume many physical qubits to represent a single logical variable. Not universal — cannot run arbitrary quantum algorithms. Quantum advantage over classical optimization solvers has not been conclusively demonstrated.
Gate Speed
20 µs per anneal (full problem solve)
Fidelity
Not applicable — stochastic sampling approach

Neutral Atom (used by QuEra Aquila)
Advantage
Large qubit counts (100–10,000+ atoms in reconfigurable arrays), programmable connectivity via atom repositioning, and operation at room temperature (atoms laser-cooled to µK). Naturally suited to analog quantum simulation.
Challenge
Gate fidelities are lower than trapped-ion systems, coherence times are shorter, and mid-circuit measurement and classical feedback are still maturing. Rydberg blockade errors limit 2-qubit gate fidelity.
Gate Speed
0.1 µs – 1 ms per gate
Fidelity
98–99.5% for 2-qubit gates
