Exactly 100 years ago, Albert Einstein laid down the foundations of quantum mechanics. After a century of curiosity, the field is revolutionised with a new understanding that information can be encoded into quantum particles. Particles – which can exist in many places at once, travel through walls and behave as a whole even when separated – enable us to build extremely powerful computers and make unconditional information security possible. No organisation, group or individual has immunity from hackers, but, by using the laws of quantum physics, we can secure our online communication, transactions and activities against all attempts to steal our personal data and most sensitive secrets, with guaranteed future proof security.
