Two energy scales are relevant during quantum annealing, * A(s)* and

**:**

*B(s)*represents the transverse, or tunneling, energy.**A(s)**is the energy applied to the problem Hamiltonian.**B(s)**is the ratio between the current time during the anneal and the total annealing time and has a value between 0 and 1.**s**

Energy scales * A(s)* and

**change during the quantum annealing process. In particular, a single, global, time-dependent bias controls the trajectory of**

*B(s)**and*

**A****. At any intermediate value of**

*B***s**, the ratio

*is fixed. We can choose the trajectory of one of*

**A(s)/B(s)***or*

**A****with time. The standard annealing schedule,**

*B**, produces a quadratic growth in*

**s****. Typical values of**

*B(s)**and*

**A(s)****are shown in the figure below.**

*B(s)*
