Very interesting. I often wonder how to answer this question accurately, or if we even know.

Makes me wonder about Shor’s algorithm though because there aren’t necessarily entangled states, right?

IonQ bought Oxford ionics?! What a shake up.

Oxford Ionics started a bit later in the game, but its unique laser-free gates have the lowest two-qubit gate errors of ANY platform. They bring other tech advances as well. Interested to see how this changes IonQ’s long term strategy

Want an AI lab notebook.

- Smart search finds past troubleshooting notes.
- Dictation and summaries to speed up note taking and making clear conclusions day to day
- automatically connect daily entries with clear timelines of changes to hardware
- give new students reports to get up to speed

Would you say -10 or -5 is bigger?

You should have to work in a lab for 1 week before proposing a new quantum error correction code.

Is there a time symmetry based code? A cousin to the time crystal?

Other QEC codes are built on symmetries

Wonder what are the error bars?

@msftresearch.bsky.social maybe switch to trapped-ion qubits?

Did you know trapped-ion qubits have demonstrated over 1 HOUR of coherence? More than 3600 seconds!

Did Microsoft announce to the world that they have a qubit, but then publish a result that isn’t a qubit?

Though NIST is the “public sector” that hasn’t stopped anyone here from being productive.

Something to consider in the emerging and potentially distributive quantum computing industry

“Experts' forecasts will always be wrong. It is simply impossible to predict with any useful degree of precision how disruptive products will be used or how large their markets will be.”

The innovator’s dilemma by Clay Christensen

Haha yes Zlatko, you’re a through and through physicist!

a) approximating implies your a physicist
b) “2 and 6/7” implies your a mathematician
C) “2.857” implies your an engineer

A friends asks, “what does 20 divided by 7 equal again?”

What do you say?

Not as a complete strategy but one with enough weight and merit that it improves the field’s overall innovation (and consequently reduces student stress and duplication)

Is quantum, now in its early stages, the right time to experiment with such a strategy? On the surface, it seems doable for academia and government labs as well as industry involvement.

2) Can this strategy be improved upon in new approach such as a massively open source strategy (instead of in a legalized monopoly)?

1) How important was the shear number of researchers to their success? Innovation vs number of researchers is… Linear? Polynomial? Exponential?

“The idea factory: Bell labs and the great age of American innovation” has got me thinking…

A legalized monopoly (AT&T) had a critical mass of researchers which—in part—enabled amazing innovation, so…

Cool experimental science. Pushing the frontier by making quantum computing useful for simulating quantum systems. Platform is trapped-ion qubits. (Has great collaboration with chemistry department and a pioneer in 2D trapped-ion crystals.)
