How Useful Are Quantum Computers?

Quantum computers today are in a state similar to that of classical computers in their infancy. The first devices took up whole rooms and could perform only simple calculations.  People were also skeptical about these machines living up to the promised potential. No one seriously predicted that we would end up with devices with a 5-inch display and more computing power than what was necessary to launch the first rocket into space.

Today quantum computers promise a major increase in performance compared to even the most powerful supercomputers. Due to the phenomenon of superposition, the state space of a quantum computer grows exponentially with a linear increase in the number of qubits. This allows algorithms to operate with large amounts of data much quicker than classical computers.

Although discussions of quantum computers often seem to quickly lead to cybersecurity talk, the world of big data continues to grow each day, and with it so does the set of problems that arise, making quantum computers more and more appealing as a means to solve them. As a result, Inside Quantum Technology is predicting that within a few years, the focus of quantum computing may be a little less on security matters and more on matters that are more prosaic. Two areas that Inside Quantum Technology’s research indicates will be early revenue generators from quantum computing are Optimization and Simulation.

A State of Optimization

Solving complex optimization problems is highly important for firms working in industries like finance, energy, transportation and security, and several of them have already shown interest in harnessing the power of quantum computing.

Simulation in Silico

In our opinion, simulating physical systems will quickly become an important application for quantum computers:
