Superconducting phase qubit coupled to a nanomechanical resonator:
... For a qubit with energy level spacing ⌬⑀ coupled with strength g to a resonator with angular frequency 0 and quality factor Q, the RWA is valid when both 兩0 − ⌬⑀ / ប兩 Ⰶ 0 / Q and g Ⰶ ⌬⑀. However, the resonant Rabi frequency, which is proportional to g, is then much smaller than the qubit frequenc ...

... where each HCa depends only on clause Ca and acts only on the bits in Ca . H(t) is defined for t between 0 and T and is slowly varying. The initial state, which is always the same and easy to construct, is the ground state of H(0). For each a, the ground state of HCa (T ) encodes the satisfying assi ...

More generally, if Q denotes a set of measurement sequences, we say that an automaton A obeys the set Q if the output for any sequence in Q matches the quantum prediction—i.e., if for any sequence in Q, the output of A could have occurred with a nonvanishing probability according to the quantum scen ...

This procedure allows us to isolate erasure events, i.e., loading intervals in which one or both atoms fail to absorb photons. Erasures reduce the throughput, but they do not reduc ...
