This paper introduces a new class of Quantum Speed Limits (QSLs) using the Sharma-Mittal entropy. QSLs are important for understanding the fundamental limits of how quickly quantum systems can evolve. The use of SME provides a new perspective on these limits, potentially offering tighter bounds or new insights into various quantum processes. The application to single-qubit systems and the XXZ spin chain model suggests practical relevance.
Key Takeaways
- •Introduces a new approach to Quantum Speed Limits (QSLs) using Sharma-Mittal entropy.
- •Applies the new QSLs to single-qubit systems and the XXZ spin chain model.
- •The results could be relevant to entropic uncertainty relations, quantum metrology, coherent control, and quantum sensing.
