What quantum technologies beyond computing deserve attention from businesses

Quantum technologies are also attractive in the fields of communications, cryptography, sensors and measurements. Unlike quantum computing, where practical use cases are still in the research stage, there are ready-made industrial products in these areas. Quantum communication uses streams of photons. The technology makes it possible to verify whether streams of single photons, which are sent continuously, have reached the recipient. They cannot be divided, measured, copied or removed without being noticed. Due to such actions, the photon is simply destroyed and cannot reach its recipient, which ensures secure communication.

While quantum key generation (QKG) is used to germany whatsapp data random keys, quantum key distribution (QKD) is required to securely distribute keys. Both technologies are essential for the one-time pad cryptosystem, which is considered the Holy Grail of encryption. In addition, quantum sensors can be used in areas where there is a need for highly accurate measurements of gravity, electric fields, time, position, and magnetic fields. The highly competitive environment means that more and more businesses will want to use them to create unique offerings.

What does the business model for quantum computing in the enterprise look like?
Given the nature of quantum computing’s evolution, it is difficult to come up with a preliminary business case for quantum computing. However, based on its potential, it can be divided into two stages. The first is to focus on short-term (1-2 years) use cases, such as optimization and encryption with DAUs and key generation with photonic ASICS. DAUs or simulators running in the cloud can solve several practical optimization problems. In addition, it is worthwhile to consider creating centers of excellence, which will lead to the accumulation of experience and the solution of relevant problems.
