Geometric Phase, of a quantum system
... Though, Shi and Du‘s approach seems to be solution, still, the bases transformation is not very clear, as it is discussed by them. But further research in this regard would lead us to achieve the error-free quantum processors. References: 1.Sjöqvist, et al., Phys.Rev.Lett., vol..85, 2845 (2000) 2. E ...

Quantum Error Correction and Orthogonal Geometry
... A quantum error-correcting code is a way of encoding quantum states into qubits (two-state quantum systems) so that error or decoherence in a small number of individual qubits has little or no effect on the encoded data. The existence of quantum error-correcting codes was discovered only recently [1 ...

Charge dynamics and spin blockade in a hybrid double quantum dot

Figure 4(a) displays the ICT as a function of V tg and the magnetic field, B. It shows that the reflectometry signal disappears with an increasing magnetic field and that, abo ...
