Over the years, quantum mechanics has paved the way of humans understanding of the physical world. From the interaction of light and matter to pervasive inventions like lasers and semiconductor transistors, it provides an account of the physical properties of nature at the scale of atoms and subatomic particles. In todays digital age, every business and even country is racing to achieve quantum supremacy. Last year, tech giant Google claimed that it has achieved quantum supremacy by developing a quantum computer called Sycamore. It has the ability to perform a test computation in just 200 seconds against the most powerful supercomputers that likely to take thousands of years to accomplish.

Despite decades of research, the quantum world still remains enigmatic and far away from the human imagination. Quantum technology refers to an emerging field of physics and engineering, relying on the principles of quantum physics. It was first delineated in a 1997 book by Gerard J. Milburn. After that, the technology has accepted immensely from the influx of new ideas from the field of quantum information processing, especially quantum computing.

When it comes to technology, advancements in both business and technological applications have always progressed hand in hand. The field of quantum technology which has been around for decades promises dramatic applications such as the creation of novel materials, advanced metrology, secure communication, and more. Many organizations realize the benefits of quantum technologies to society, industry and academia. Governments are also investing in research and commercialization of these technologies, while universities are exploring implausible applications.

China, for instance, recently demonstrated secure quantum communication links between terrestrial stations and satellites. In the journalNature, the team of 24 scientists reported new progress of successfully testing the transmission of a secret key for encrypting and decrypting messages between a satellite and two ground stations located roughly 700 miles apart. The method enlisted quantum entanglement, an idea of modern physics that seems ridiculously at odds with common sense.

In anarticle, Paul Martin, Quantum Technology Expert noted that with the latest feats of engineering harnessing more of the potential of quantum mechanics, quantum technology is gaining new hype 50 years later it became a part of human lives through nuclear power. According to him, we are now starting to control quantum entanglement and quantum superposition. That means quantum technology promises improvements to a broad range of everyday gadgets, including more reliable navigation and timing systems; more secure communications; more accurate healthcare imaging; and more powerful computing.

Along with private companies capital investments, government support of quantum technologies has created an optimistic environment for the future of this technology. For example, the UK Government has invested around 400 million in the UK National Quantum Technologies Programme to develop the countrys strong research capabilities in Quantum Technologies. The programme is a collaborative initiative to advance technology and provide long-term benefits to society. Within the programme, four quantum technology hubs were created, each with a particular focus.

On the other side, the Indian Government in the recent 2020 budget announced plans to invest US$1.12 billion in quantum computing research over the next five years. The US, China, Japan, Germany, and Canada have already announced ambitious schemes to bolster quantum computing programs.
