Ilana Wisby Updated 2025-07-16
Founding CEO of Oxford Quantum Circuits.
As mentioned at www.investmentmonitor.ai/tech/innovation/in-conversation-with-oxford-quantum-circuits-ilana-wisby she is not the original tech person:
she was finally headhunted by Oxford Science and Innovation to become the founding CEO of OQC. The company was spun out of Oxford University's physics department in 2017, at which point Wisby was handed "a laptop and a patent".
Did they mean Oxford Sciences Enterprises? There's nothing called "Oxford Science and Innovation" on Google. Yes, it is just a typo oxfordscienceenterprises.com/news/meet-the-founder-ilana-wisby-ceo-of-oxford-quantum-circuits/ says it clearly:
I was headhunted by Oxford Sciences Enterprises to be the founding CEO of OQC.

Unitary group Updated 2025-07-16
Complex analogue of the orthogonal group.
One notable difference from the orthogonal group however is that the unitary group is connected "because" its determinant is not fixed to two disconnected values 1/-1, but rather goes around in a continuous unit circle. is the unit circle.

Brazil Updated 2025-07-16
An awesome country, with amazing people and natural resources, and without an evil government like China.
When visiting Brazilian cities coming from Europe, one of the things that shocks the most is the amount of motorcycles. It seems that the poorer the country, the less people's lives are worth, and the more motorcycles there are.
Another thing that was shocking is the amount of phone spam when you get a new SIM card, some legal and some likely illegal. Everyone is desperate for cash it seems on a poor country, and everyone fights hard for it.
Quantum threshold theorem Updated 2025-07-16
This theorem roughly states that states that for every quantum algorithm, once we reach a certain level of physical error rate small enough (where small enough is algorithm dependant), then we can perfectly error correct.
This algorithm provides the conceptual division between noisy intermediate-scale quantum era and post-NISQ.
