The Easiest Job in Quantum Computing – Being a Cynic
Don’t mistake the noise of cynicism for the signal of intelligence. If someone validates themselves as a useless cynic - unwilling to provide anything beyond scoffs and derision - don’t waste your energy getting dragged into their performative pessimism. Instead, direct…

Why Companies May Need a Chief Quantum Officer (CQO)
In my opinion, forward-thinking organizations should consider creating a Chief Quantum Officer (CQO) role. Much like those historical electricity executives, a CQO would spearhead the adoption of a disruptive technology that is revolutionary, promising - but widely misunderstood. It’s a…

Magic States: A Key to Universal Fault-Tolerant Quantum Computing
Magic states are special quantum states that enable the universal operations needed for any quantum algorithm, yet which are not themselves easy to produce or protect. In essence, magic states supply the "extra quantum sauce" that elevates a protected quantum…
