... The measurement of non-commuting operators in a quantum system is at the root of the well-known paradoxes of quantum mechanics. For example, the Kochen-Specker paradox involves measurement of a set of non-commuting operators with mutually commuting subsets [1, 2]. The Bell inequalities are similarly ...

Controlled Hawking Process by Quantum Information
... view. This implies that the classical black holes do no remember the detailed information of falling matters. However, the black holes still remember what they swallowed in a quantum mechanical way. Via the QET protocol, we can extract energy from the black holes by using correct measurement results ...

Are there basic laws of quantum information processing?
... I. For a compound quantum system the sum of information contained in the subsystems and the information contained in entanglement is conserved in unitary processes. As an illustration of the above principle can serve the observation [15,16] that during quantum copying process the information is not ...

Coherent population trapping of an electron spin in a single
... orders in the driving field and to first order in the probe. Assuming that γs is a few orders of magnitude larger than Γs (as we show below), we find γ T−X+ /2π, and γs /2π equal to (0.54 ± 0.1) GHz and (40 ± 12) MHz, respectively. The value of 40 MHz corresponds to the electron spin decoherence tim ...

Since nuclear relaxation times are large, this point deserves some discussion. In fact, raw data acquisition time in experiment [15] was 0.1 s per point, which is probably less tha ...
