Multiple-valued quantum circuit synthesis, using permutation-based fast transforms, is introduced. Since the reduction of power consumption is a major requirement for circuit design in future technologies, such as in quantum computing, the main features of several future technologies must include reversibility. Consequently, the new quantum circuits can play an important task in the design of future circuits that consume minimal power.

Computing plays a significant role in power system analytics. As mathematical challenges increase and data become the epicenter of modern decision making, substantial progress needs to be made to draw on emerging analytics and computing technologies. Quantum computing is a ground-breaking technology in information processing that can support the global efforts in addressing power system challenges and in further envisioning the grid of the future. However, despite extensive research activities in quantum computing applications in various sectors, its application to power systems has remained mostly unexamined. It is necessary to have an across-the-board view of the quantum computing technology applications in power systems, and in particular, in building the grid of the future. This paper discusses the essential elements of quantum computing and presents a review of issues concerning this technology. The paper further provides an in-depth discussion of the potential of quantum computing in improving analytical and computing capabilities in solving multiple power system problems.

The current realities of the cyber domain could be radically disrupted by the advent of quantum communications and quantum computing. The consequent challenges for future cyber security and strategy require a nuanced analysis of these technologies and their likely employment by major powers. The employment of quantum cryptography can create quantum communications systems that are theoretically unhackable. Within the foreseeable future, quantum computing will be powerful enough to overcome most of today's advanced encryption techniques, rendering the majority of existing commercial, government, and military systems unprecedentedly vulnerable. These quantum technologies could respectively tend to advantage defense and offense in the cyber domain. While the “shield” enabled by quantum communications would contribute to technological deterrence through denial, the asymmetries of vulnerability that might result could potentially undermine military cyber stability, while exacerbating the risks of misperception through complicating intelligence collection. In the more distant future, the advent of quantum computing will enable unique offensive power that could leapfrog existing cyber capabilities. The strategic impact of these disruptive technologies will depend upon the approaches of great powers, particularly the U.S. and China, which have become leaders in this technological domain.
