Analysis of a Quantum Error Correcting Code using Quantum
... Our model of a quantum error correction system consists of three processes: Alice, Bob and Noise. Alice wants to send a qubit to Bob over a noisy channel, represented by Noise. She uses a simple error correcting code based on threefold repetition [13, Chapter 10]. This code is able to correct a sing ...

Quantum-dot lithium in zero magnetic field: Electronic properties
... So far, full energy spectra of an N -electron parabolic quantum dot in zero magnetic field, as a function of the interaction parameter λ, were published only for N = 2 (quantum-dot helium11 ). For larger N a number of results for the ground state energy of the dots were reported at separate points o ...

The Wave Function
... The Heisenberg relation has an immediate interpretation. It tells us that we cannot determine, from knowledge of the wave function alone, the exact position and momentum of a particle at the same time. In the extreme case that ∆x = 0, then the position uncertainty is zero, but Eq. (3.14) tells us th ...

Relativistic Adiabatic Approximation and Geometric Phase
... Although the original approach of Garrison and Chiao [8] does not require the evolution of the field to be adiabatic, as seen from the example studied by Anandan and Mazur [10], most often one cannot compute the geometric phase analytically without assuming the adiabaticity of the evolution. This su ...
