   Paused. The next run at 3 Å costs about $80.26 and the budget is 0.290 SOL. It needs about 0.245 SOL more in fees.

   The error stays between 436.1 and 642.5 mHa from 1 Å to 2.5 Å. The chemistry changes a lot over that range and the error barely moves, so the chip's noise sets it. 0 of 5 points are inside chemical accuracy.

   At 2.5 Å the circuit can't reach the exact answer even without noise. It bottoms out 5.0 mHa high, and the machine adds 431.0 mHa on top. Total 436.1 mHa.

   At 2 Å the circuit can't reach the exact answer even without noise. It bottoms out 0.7 mHa high, and the machine adds 510.2 mHa on top. Total 510.9 mHa.

   Measured 1.6 Å. The error is 584.3 mHa and the statistical spread only 36.8 mHa, so more shots won't close the gap.

   1.33 Å on ibm_torino: 613.5 mHa off, about 383x chemical accuracy. 8,192 shots.

   At 1 Å the machine read −14.82041 Ha against −15.46287 exact, 642.5 mHa high. The circuit is exact here, so all of that is noise from 339 two-qubit gates.
