C191 - Lectures 8 and 9 - Measurement in
... To actually perform a measurement, we bring our system into contact with a meter. The meter, since it is just another physical object, is a quantum system whose initial state we shall suppose is blank, which we’ll notate as |?i. When the system and the meter are brought into contact, they interact w ...

SOLID STATE QUANTUM COMPUTING USING SPECTRAL HOLES
... matching is that the Λ transition in each atom must be two-photon resonant. This can be realized by choosing the laser frequencies appropriately. It is also necessary to make sure that there is only one atom per spectral channel. Figure 2: Relevant energy levels and transitions required of two spect ...

... can follow. Furthermore, we can assume that every computational path on an input of a fixed length has the same depth [16, page 254]. In other words, every computational tree of an NTM can be thought of as a perfect binary tree of polynomial depth. When we refer to a machine as precise, we will assu ...
