# Is there a way to tune the coefficients in the transverse field?

I'm interested in making some coefficients in the transverse field equal to zero.

Specifically, I want \Delta_j = 0.

The reason I would like this is because I what to:

1- Initialize the quantum state

2- Do reverse annealing

3- Do annealing

4- To not destroy the qubit state \sigma_z_j by allowing tunneling (after reverse annealing).

The rational is that if \Delta_j = 0, then [H_p, \Delta_j \sigma_x_i] = 0, and the reverse annealing should not directly impact the initial qubit state.

Thanks!

David J(Report)Hello,

The transverse field is not programmable for specific qubits, but it is possible to accomplish effects like you've described.

One way is to bias qubits towards a specific value of spin up or spin down, using flux_biases or large biases applied h values. There is some information in the Flux-Bias Offsets section of the Error Correction Features documentation.

Another way is to use anneal_offsets which allow for qubits to be annealed sooner or later in time. This is used when adjusting for early Freezeout Points for qubits in chains.

Hopefully this helps with your implementation.

Please don't hesitate to reach out with more questions.
