In such a system we have recently demonstrated phase-coherent transfer of a single magnon from one ensemble to another via an optical resonator serving as a quantum bus that in the ideal case is only virtually populated [10].

... Back to our 3-qubit string If we measure the 3 qubits the probability of measuring a particular string will equal the sum of the squared magnitudes of that strings coefficients. Our quantum superposition has collapsed to a classical state. Semi-classically, we can think of the system as being one o ...

Important conclusion: An electromechanical instability is possible even if the initial displacement of the shuttle is smaller than its de Broglie wavelength and quantum fluctuations of the shuttle position can not be neglected. In this situation one speaks of a quantum shuttle instability. Now once ...
