Quantum Computing

Quantum computing is the use of quantum mechanics within computing in order to decrease the number of processes needed to find a solution to a problem. Quantum computers use qubits (quantum bits) instead of bits and these qubits can be subject to a manipulation that can’t be done to classical bits, such as quantum entanglement and superposition. There are a number of objects that can be used as qubits, photons, nuclei or electrons which means that while classical computers today are being limited because computer components cannot be decreased any further in size, quantum computer components would only have to be a few atoms in size.

Quantum computers hold many advantages over classical computers. One such advantage is that while classical bits can only be presented as zeros or ones at any given time, qubits can exist in any superposition of these values up until they are measured. When harnessed, this allows quantum computers to process a vast amount of calculations simultaneously as 1s, 0s and superpositions of both 1s and 0s are used. This means that certain processes that were once thought to be impossible are now possible with the use of this new technology. This also means that while classical bits can represent n amount of information, where n equals the number of bits being used in the process, qubits, on the other hand, represent two to the power n amount of information in which case n instead equals the number of qubits being used. This means that if sometime in the future it was possible that a quantum computer could harness 300 qubits, n to the power of 300 would mean that this quantum technology would be able to use amounts of information equal to the number of particles in the universe.

Although quantum computing is still in the early stages of research, there are still some uses for this technology in the present day as it still somewhat trumps classical computing. An algorithm named “Shor’s algorithm” proved that where a classical computer would factor and extract discrete logarithms and find prime factors in exponential time, quantum computers would in polynomial time (Warren, 1997) (Bennett et al., 1997). A polynomial time when compared to exponential time is very efficient and Shor’s algorithm has already given a place to quantum computing in today’s world of mathematics but this raises the question of if all other mathematic functions could also be efficiently solved in quantum polynomial time.

Electromagnetic Modelling and Antenna Simulation via Opensource Software

Commercial electromagnetic simulation (EM) software packages such as CST Microwave Studio and  ANSYS HFSS are widely used in commercial applications and educational purposes. Based on my experience, they provide very accurate results which match measurements in most antenna works. On the other hand, there are also very solid opensource software and applications which may also provide similar results in some applications. Antennas are also used in radio telescopes While commercial EM software suits usually have very good documentations, easy-to-use interference, and result visualisation and navigation tools, opensource EM software suits might consist of only the solver and documentation which explains how it should be used and implemented for design and simulation via an interference and a programming language such as Python, MATLAB, C++ . As they are opensource, it is also possible to edit their codes and advance their functions and performance. Thus, these features makes opensource

15 Best IoT Energy Startups

15 Best IoT Energy Startups Energy is one of the common problems all around the world. Without it, all our technology will be useless. The interesting thing about energy is despite we have numerous sustainable and renewable energy sources; we still rely on scarce sources. Renewable energy is important because it provides a clean, sustainable and unlimited source of energy that can reduce our dependence on finite and polluting fossil fuels, helping to mitigate the impacts of climate change. Additionally, renewable energy can lead to local economic development, improve energy security and reliability, and create new jobs and industries. Wind power is one of the most important renewable energy sources.  On the other hand, the Internet of Things will change the trends in the energy industry as well. In fact, the number of IoT energy startups is worth mentioning. If you are interested in this field and love the idea of taking advantage of new technologies, then you need to know the followin
