The use of Quantum Information techniques (quantum 2.0) promises to outperform classical information processing techniques for some tasks. This has recently motivated a large investment in the research of quantum technologies, but there are still many that are sceptical about the real advantages of quantum technologies. In my talk I will review briefly the different technological platforms for implementing a quantum information processing system. Then I will concentrate on the integrated quantum photonics effort at Bristol. I will highlight the need for cryogenic systems and possible and impossible routes to avoid it.
