The Internet of Things (IoT) is one of the emerging fields which has been developing day by day since 1990 but still having issues like security, privacy, data theft and server requirements to deal with big data. Quantum computing solves most of the problems in IoT but it is still under research stage and can take about a decade or two to get publically available for public use. In this paper, we begin with general introduction on IoT and Quantum Computing and continue on with problems that can be faced during integration of IoT and Quantum Computing. After that, we will also point out the solution to encounter these integration issues in context of efficiency and cost. Finally, we point out the benefits of integration of both fields to existing IoT network architecture.

Traditionally causes come before effects, but according to modern physics things aren't that simple. Special relativity shows that `before' and `after' are relative, and quantum measurement is even more subtle. Since the nonlocality of Bell's theorem, it has been known that quantum measurement has an uneasy relation with special relativity, described by Shimony as `peaceful coexistence'. Hardy's theorem says that quantum measurement requires a preferred Lorentz frame. The original proofs of the theorem depended on there being no backward causality, even at the quantum level. In quant-ph/9803044 this condition was removed. It was only required that systems with classical inputs and outputs had no causal loops. Here the conditions are weakened further: there should be no forbidden causal loops as defined in the text. The theory depends on a transfer function analysis, which is introduced in detail before application to specific systems.
