I built PlanqTN Studio from scratch in 4 months with the help of
@cursor_ai
. It was a fantastic experience!
💻 Learned React, Zustand, Supabase, Terraform
⚡️ AI prototyping: 6–7× faster
🛠️ Full dev: ~2–4× faster

Massive thanks to:
🧠 Charles Cao & Brad Lackey for the foundational QL framework + support
🎓 June Vanlerberghe (Duke MS student) already using PlanqTN in research
🧑‍🏫 Ken Brown for giving me the space and support to do this
🪙 Unitary Fund for the microgrant + encouragement

Coming soon:
📚 QL layout database
⚙️ Optimized contraction (C++ / GPU)
🔄 non-Pauli Logical ops
🧠 Qudit support
If this sounds cool — we’re open source and would love contributions!

Weight enumerators? Yep.
PlanqTN + Cotengra = compute them on any QL layout.
⚡ Way faster than brute force (though still #P-hard) for most interesting cases.

Tensor networks meet actual usability.

When we've been there in a group
closed under the sum,
To represent we took the trace,
character has first begun.

Density matrices are fun
to observe with the trace!
Mean was lost, but now is found,
in the large Hilbert space.

’Twas trace that taught my heart to fear,
and trace my fears relieved;
How precious did that trace appear
the hour I first believed!

No, I only created one account. Interesting...
