What makes a great quantum circuit README?

After rewriting 50 READMEs, I settled on 4 layers:

1. Intuition — the physical picture, no equations
2. How it works — what each gate does to the state
3. The math — state evolution for those who want proof
4. Expected output — what you should see when you run it

Each layer for a different reader: beginner → student → physicist → experimenter.

Most READMEs I've seen only have layer 2. Which do you skip to first?

Circuit spotlight: Bell State

Creates |Φ+⟩ = (|00⟩ + |11⟩)/√2 — the simplest entangled state.

Two gates. Two qubits. One of quantum mechanics' deepest phenomena.

I audited 50 quantum circuits line by line. Three bugs:

1. My H₂ VQE had a wrong Hamiltonian coefficient. The optimizer still converged. It gave the right answer. The Hamiltonian was wrong.

2. 4 PennyLane circuits broke after a NumPy update. Version pinning matters.

3. Qiskit's little-endian qubit ordering silently changes results when porting between frameworks.

Lessons: "it converges" ≠ "it's correct." Full write-up Monday.

"‘It’s a real shock’: quantum-computing breakthroughs pose imminent risks to cybersecurity

Two analyses suggest that quantum computers could crack ubiquitous security keys and cryptocurrencies before the decade is over.

The world could be caught off guard by quantum hackers before the end of this decade — much sooner than previously expected. This is the take-home message of two preprint studies posted independently on 31 March, one by a team at Google1 and the other by Oratomic2, a start-up company in Pasadena, California.

Digital technologies relying on encryption and authentication methods — such as credit card systems, cryptocurrencies and Internet communications — have long been known to be vulnerable to future quantum computers capable of cracking security measures faster than even the largest conventional supercomputers can.

But the assumption among researchers and cybersecurity companies working on quantum-proof encryption technologies has been that these machines would not become a serious threat to digital security for at least ten years.

The preprints, both of which suggest that quantum computers capable of cracking current encryption systems could soon become available, have created a sense of 'renewed urgency', says Jintai Ding, a mathematician at Tsinghua University in Beijing. The findings have prompted 'many discussions among people I know, ranging from academics to bankers and to people who care about cryptocurrencies', says Ding.
