Quantum computing has been the talk of the town recently, due to two very different reasons:

• A barrage of marketing from major tech players and frequent media reporting
• It has the potential to compromise everything from digital transactions to emails and digital signatures.

Quantum computing promises to provide a new way of storing information and retrieving information that is different from the analogue and digital approaches of the past. Many proponents of quantum computing believe this will lead to new computers that are much faster and capable of new algorithms that aren’t available today. Some commentators point to the cost of these new quantum computers and question how revolutionary this technology will be in practice.
