Just as a reminder, Quantum technologies are used in three very different and distinct markets: Quantum Computing, Quantum Communications and Quantum Sensing and Metrology. If you don’t know the difference between a qubit and cueball, (I didn’t) read the tutorial here. Summary – There’s been increme...
