... The typical classical single-bit error is the bit-flip: 0 ↔ 1. If we assume a simple error model (the binary symmetric channel) in which bit flips errors occur on each bit independently with probablility p per unit time, we expect a bit to be corrupted after O(1/p) steps. (In general, we assume p ≪ ...

... which approaches unity as ⌫t is increased with ⍀t held fixed, in which limit the system is again frozen in the initial state. The discrete and continuous systems can be mapped onto one another if we equate ↔ ⍀t / 2 and M ↔ M eff = ⌫t / 4 = ⌫ / 2⍀. The equivalence between the two systems can be un ...

... concept of reduction between two models of a single, fixed system [40]. Here, I understand a “model” to be specified by some choice of mathematical state space (e.g., phase space, Hilbert space) and some additional structures on that space that serve to constrain the behavior of the state (e.g., Ham ...

Distinguishing mixed quantum states: Minimum
... Stimulated by the rapid developments in quantum communication and quantum cryptography, the question as to how to optimally discriminate between different quantum states has gained renewed interest [1]. The problem is to determine the actual state of a quantum system that is prepared, with given pri ...
