Abstract
The time required for a system to change from initial to orthogonal state is known as Quantum speed limit time (QSLT). It has been used to quantify the speed of evolution of quantum systems. Quantum speed limit time is inverse of the quantum evolution. We have investigated the effect of QSLT for corelated Markov noise channels. It has been observed that QSLT under noise channels increases or decreases for a fixed interval of dissipation function. In our work, we consider a two-qubit atomic model for a global system-bath interaction in presence of Markov noise. The evolution of QSLT has been studied under such interactions and its physical significance is also discussed. We hope our new findings, regarding utility of such speed limit will involve research in areas like communication, quantum computation, computation speed in quantum communication, precession limits in quantum metrology.
