Description
Adiabaticity can be used to improve accuracy and precision of many quantum control procedures such as quantum annealing, adiabatic quantum computing and ground state preparation. However, processes need to be implemented very slowly to achieve the adiabatic limit, lengthening control sequences and increasing the susceptibility of the system to decoherence. One approach to overcoming this problem is to apply counterdiabatic driving, which can be defined via a quantity known as the Adiabatic Gauge Potential (AGP). The AGP characterises the adiabaticity of a system, and in general is a difficult quantity to compute. We present a new approach to symbolically computing the AGP using commutation relations, which we apply to the Ising graph Hamiltonian class as an example. This new approach allows efficient computation of the AGP on larger graphs than were previously possible with other methods.
