QPU-Specific Characteristics#

Section Physical Properties provides attached documents describing physical properties particular to the QPUs available through Leap. For each QPU, the associated document includes a summary of its physical properties and plotted data showing the anneal schedule and other details.

The values provided in these documents are the physical properties of a calibrated QPU. They are not QPU specifications.

Section Anneal Schedules provides attached spreadsheets describing the annealing-schedule functions and normalized annealing-waveform values that you need to compute the energy of a problem at a specific point in the annealing process, for each QPU available through Leap. Provided here are the values to use for the A(s) and B(s) terms in the Hamiltonian for each value of the anneal fraction, s, between 0 and 1 in increments of 0.001. Units for these terms are GHz, where the conversion from energy in Joules to Hz is through a division by Planck’s constant; i.e.,

\[ \begin{align}\begin{aligned}A(s)_{\text{[GHz]}} &= \frac{A(s)_{\text{[Joules]}}}{6.62607004 \times 10^{-34} \times 10^9}\\&= 1.5092 \times 10^{24} A(s)_{\text{[Joules]}}\end{aligned}\end{align} \]
