The business instances along with the prospects for quantum computing - despite of being overstated at times- have undeniably been fascinating. The potential benefits of quantum computing expected for a wide-ranging enterprises have been remarkable.
A number of tech giants including Google, Microsoft, IBM and Intel have been making huge investments within the extent, with various major governments ensuing suit. Recently, the Trump government passed a bill offering nearly $1.2 billion (USD) towards the quantum research, which was followed by the European Union and China, by taking a similar move of pledging almost €1 billion for the cause and investing billions of dollars within the technology for several years respectively.
Although it is believed that the quantum advantage (i.e. creating a quantum computer that will be serve as an enhanced version of traditional computing at a really valuable task) would still be far away from achieving, however the future prospective for these systems are both tremendously exciting as well as to some extent challenging. This is mainly due to the fact that in addition to the positive uses of quantum-level technology, there are a few negative ones. Possibly one of the key concern is the ability of the quantum computing to entirely disrupt the present encryption techniques, pushing an immense quantity of encrypted data at threat of being attacked at any time. This data at threat might include vital financial statistics or certain very confidential information that can have a huge impact over the business.
