Google’s supremacy demo and Amazon jumping into quantum computing are the biggest stories, but progress in variational (aka hybrid quantum/classical) algorithms is quietly one of the most important themes of the year in quantum.
In 2019 I proved that the variational model of quantum computation is universal. 100% different than Lloyd's QAOA "reachability" result. New tricks awaiting applications and a general discussion RE practical limitations without error correction await.

ChatGPT has made it possible for *anyone* to run an algorithm on 10,000+ GPUs/CPUs in an instant. You don’t need to write code or even to type (voice to text). That seems really, really important when thinking about some of the structural trends that this is going to kick off.

A simple test of whether a company is a tech company or not is if their problems can be fixed by writing more and better code.
If not, it isn’t a tech company.

As machines become broadly available over cloud and QEC and FTQC become experimental fields rather than purely theoretical, practical codes (ie work on real systems) for universal FTQC (incl. non-Clifford gates) with total overhead <100x will become commonplace.

While I'm an optimist for most quantum hardware modalities (Majorana's being one big exception), I view this as a pretty strong statement of a) superconducting as the leading modality right now; and b) the strong likelihood that superconducting continues to win in the QEC era.

This is pretty cool - AWS announces a public quantum computing (QC) platform named after my grandfather's notation for wave functions. Great that even in its infancy, QC is already getting democratized, not centralized in the hands of a few powerful research groups.

Not a bad idea. Practically speaking leading/shaping rounds and setting terms with founders vs joining once everything is largely set are *really* different.
We should probably be splitting venture into two categories:
VC’s who lead deals, and VC’s who don’t.
