Abstract

Some of our previous research showed some interesting results regarding the effect of non-zero temperature on a specified quantum computation. For example, our analysis revealed that more Grover iterations are required to amplify the amplitude of the solution in a quantum search problem when the system is found at some finite temperature. We want to further study the effects of temperature on quantum entanglement using a finite temperature field theoretical description. Such a framework could prove to be useful for the understanding of computational dynamics inside a quantum computer. Other issues that we will address in our discussion include analytical descriptions of the effects of the temperature in the Von Newman entropy and others as a measure of entanglement.
