    • The state of two qubits can be described in the Bell basis, spanned by four maximally entangled states [2]: the singlet state |↑↓〉 - |↓↑〉 and the triplet states |↑↑〉 + |↓↓〉, |↑↓〉 + |↓↑〉 and |↑↑〉 - |↓↓〉, respectively

    • note
    • To preserve a superposition or an entangled state, no measurement that would cause the projection into some other states is allowed. A Bell-state measurement can be accomplished by transforming from the Bell basis [14] into the measurement basis, prior to the individual state measurement of each qubit. Therefore, the Bell measurement provides information about which of the four Bell states the two qubits were previously in, but no information about the states of the individual qubits. We realize this by a conditional (disentangling) phase gate followed by individual read out of the two qubits [18]

    • note
    • The statistical limit is governed by quantum projection noise, arising due to the statistical nature of projecting a superposition state into one eigenstate by the measurement
