Quantum Error Correction and Orthogonal Geometry
... A quantum error-correcting code is a way of encoding quantum states into qubits (two-state quantum systems) so that error or decoherence in a small number of individual qubits has little or no effect on the encoded data. The existence of quantum error-correcting codes was discovered only recently [1 ...

... It is, however, helpful to highlight just a few key concepts. We can characterize bounds on the security by comparing the Shannon mutual information57 for Alice and Bob I(A:B) and for Alice and an adversary, traditionally called Eve, I(A:E). It is intuitive (and can be proven58,59) that if Bob has m ...
