past me signed up for a bunch of stuff, now I can't sit without a constant guilt mtsm

Why does claude not have a sense of time? Why does it think every message in the chat happens in the same day?

imma breath though this lab no issue #qiskitsummerschool #deadlineisclose
THIS WAS AMAZING!!!
seeing recursion, BFS, and binary search twin in the notebook was like reuniting with old friends I haven't seen in years

How to interpret quantum hardware specs
- Number of qubits: how many physical qubits the chip has. (Note: "programmable" = the ones you can run on, "physical" = total on the chip.)
- Basis gates: the only gates the hardware can natively run. Your code gets transpiled so it's expressed using just these.
- Readout error: the error during measurement. Lower is better.
- 1Q / 2Q gate error: the noise each gate adds. Two-qubit gates are ~10× noisier than single-qubit ones, so this is the number that judges a device.
- CLOPS (Circuit Layer Operations Per Second): how many gate layers run per second. Throughput, like classical computers. Higher = faster (not more accurate).
- T1 (energy relaxation): time for excited |1⟩ to decay to |0⟩.
- T2 (dephasing): time before phase coherence between |0⟩ and |1⟩ is lost.
The longer T1 and T2, the deeper the circuit you can run before noise wins.
