Determining the most ideal practical quantum decoherence-reduction method by simulating superconducting qubit coherence rates in a Qiskit Pulse program and IBM’s Dyanmic Decoupling Program

Quantum decoherence is the loss of quantum information preserved in quantum states. This phenomenon occurs because the wavefunctions of the qubits have interference, which allows them to change their frequencies and wavelengths when other waves are applied to them. While the physics behind using gates to qubits is the application of waves to qubits in order to change their properties and thus its state, these properties can also be altered by environmentally occurring waves, such as heat and radio waves. However, many decoherence-reduction methods have been discovered and can be viably implemented into quantum systems to mitigate or counter quantum decoherence to a degree. We perform an assessment to determine the best method to reduce quantum decoherence by assessing the qubit coherence of qubits under each reduction scheme by plugging in a percentage value stating how much larger the qubit coherence time is into a proposed Qiskit Pulse program that utilizes dynamic decoupling much more accurately and quickly than the standard dynamic decoupling program available in the Qiskit Pulse documentation, “Calibrating Qubits with Qiskit Pulse.”
