Advancements in Battery Technology

Abstract

The main focus of this chapter is on the Armonk single-qubit processor, and the authors give a full account of what IBM's quantum chips can do, specifically as quantum batteries. The goal is to find the best balance between charging time and stored energy by using the Pulse functionality offered by some IBM Quantum processors through the Qiskit package. To do this, the authors look at the pros and cons of several common drive profiles used to charge these small batteries. They also look at how different starting factors can change how quantum batteries work. This research shows that the mistakes that happen naturally at the start of qubit activation don't have a big impact on how energy is sent or stored. On the other hand, these effects may slow down apps that use quantum computing. Interestingly, this could make things run more smoothly. This is strong proof that IBM's quantum devices meet the requirements to be called stable quantum batteries, similar to the cutting-edge devices that were just published in scientific journals.
