Quantum Error Correction and Orthogonal Geometry
... that S̄ ⊥ has minimal weight 3. This gives a quantum code mapping 3 qubits into 8 qubits which can correct one error. The same code was discovered by Gottesman [8], who used similar group-theoretic techniques, and by Steane [9]. Example 4. By duplicating the 5-qubit code (10) and adding two vectors, ...

... Because the answers can now depend on what the interviewer is asking the other person. Alice and Bob can agree that they should give opposite answers if both are asked the S question and otherwise they should give the same answer. For many Alices and Bobs this gives < B >= 4 ≥ 2. Alice and Bob can h ...
