A bit of care is required with this regard: whilst the states {|ii} of both the qubits can physically be virtually arbitrary (e.g., the ”ground”, |gi, and ”excited”, |ei) states, all the consi ...

An additional feature of DCQD is that all the required ensemble measurements, for measuring the expectation values of the stabilizer and normalizer operators, can also be performed in a temporal sequence on the same pair of qubits with only one Bell-state generation. This is because at the end of ea ...

Mathematical structure of magnons in quantum

All quantum character of the magnons vanishes if one chooses the magnetic field h and/or the interaction constants (D(q)) and/or the temper ...
