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.

this lab was good
I learned a lot about hardware properties (gate errors, readout errors, coherence times), comparing IBM devices and worked on dynamic circuits.

THIS WAS AMAZING!!!
seeing recursion, BFS, and binary search in the notebook was like reuniting with old friends I haven't seen in years

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

oh woow, first time finding binary search in qc
apparently it helps in reducing the depth of GHZ circuit

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

this is by far the best sketch I've ever made and I'm scared of coloring it and ruining it
