A 98-qubit trapped-ion processor shows that measured gate errors accurately predict performance in circuits too complex for classical simulation.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

These component infidelities are predictive of system-level performance in both random Clifford circuits and random circuit sampling, the latter demonstrating that Helios operates well beyond the reach of classical simulation and establishes a new frontier of fidelity and complexity for quantum computers.

C2weakest assumption

That the measured component infidelities from individual gates and operations accurately predict the behavior of large-scale circuits without significant additional errors introduced by the rotatable ring, parallelization, or overall system scaling.

C3one line summary

Helios achieves 98 qubits with single-qubit gate infidelity 2.5(1)×10^{-5}, two-qubit 7.9(2)×10^{-4}, and SPAM 4.8(6)×10^{-4}, enabling circuits beyond classical simulation.

[1] We measure SPAM errors by preparing 16 qubits in the 8 operation zones in the|0⟩or|1⟩states, and measuring each qubit

[2] Importantly, spontaneous emission causes leakage outside of the com- putational subspace 2000

[3] We validate the performance of the maxi- mally entanglingR ZZ (π/2) gate (referred to as the 2Q gate) using both Clifford 2QRB and cycle benchmark- ing (CB)

[4] Transport idle memory errors Qubits idle during ion transport and cooling and incur memory errors due to spatiotemporal magnetic field inho- mogeneities, with their impact being heavily dependent on t

[5] The resulting spontaneous emission can lead to bit-flip, leakage, or dephasing errors
