00 🗞 Tech News
Two recent reports on quantum computing provide valuable information to non-experts. These are probably the most thorough documents tailored for an audience outside that of academic circles, after Jason Palmer’s extensive reporting on quantum technologies for The Economist in early 2017.

The first document is an extensive report by BCG Munich on quantum computing. This is the most detailed such document on this space from a strategy consultancy or corporate player, notably devoid of unnecessary hype. Lots of information to navigate this field, including information on players, startup rounds and maturity of applications. Also featuring: Quantika, among players in the first figure, and the BCG matrix, or better its quantum-advantage version. Link

A recent workshop provided the opportunity for a very thorough, technical, but at the same time accessible, report on the stage of quantum computing from the perspective of experts of the field, aimed at computer scientists and non-experts, committed by the Computer Research Association. Nice plots. Link

Both reports capture the growing effort of Honeywell, a defense contractor, in building an experimental quantum computing team, joining competitors.

In an interview accompanying BCG’s first white paper, Chad Rigetti discloses that its company has so far raised almost $120 mln in funding. The company plans to launch a 128-qubit quantum processor by next Summer. Link

Daimler, the car maker, is looking into quantum computing with Google research. Link

Google researchers have started a series of videos on quantum computers and how to program them. Link
