IBM reportedly produced a 127-qubit superconducting quantum computer in November, intends to unveil a 400-qubit processor this year, and aims to produce a 1,000-qubit processor in 2023. They are building IP, training, learning the development stack, designing algorithms and understanding the likely effect on their business. These firms see the change coming and don’t want to be left behind which is why companies like JP Morgan, Goldman Sachs, Rolls Royce, BMW and VW are investing now. There is no doubt that the field is evolving at a rapid pace and breakthroughs will come sooner than we expect which is why organisations have to start looking a quantum computing now.
In order to protect against this, Lyubashevsky says that organisations and state actors should already be updating their cryptography to quantum-safe algorithms ie. A primary concern is that quantum computers of the future could be possessed of such powerful calculation ability that they could break the encryption protocols fundamental to the security of the Internet that we have today. Quantum technology can address complex societal challenges, but it can also be used maliciously by nation-states during warfare.
For example, quantum computing is expected to excel at tasks such as integer factorization and simulations … Read More
