... Rule 1 (State Description) N states, probability vector Rule 2 (Evolution) N x N stochastic matrix Rule 3 (Measurement) A measurement with k outcomes is described by k N dimensional real vectors with positive components. If we sum over all of these k vectors then we obtain the all 1’s vector. If our ...

... Vidal showed that in that case a succinct description is possible, with O(n) parameters rather than 2n, and that the description can be easily updated as the state evolves (if the interactions are local). This makes precise the idea that entanglement is the source of a quantum computer’s power: if t ...

... Wodkiewicz @10#. Mixing of the signal and coherent fields with controlled amplitude on the beam splitter may serve for reconstruction of the Wigner function and other distribution functions using the photon counting only. Techniques similar to the quantum-state reconstruction have been suggested for ...

Quantum Mechanics: Postulates
... In order for Ψ(x, t) to represent a viable physical state, certain conditions are required: 1. The wavefunction must be a single-valued function of the spatial coordinates. (single probability for being in a given spatial interval) 2. The first derivative of the wavefunction must be continuous so th ...

SOLID STATE QUANTUM COMPUTING USING SPECTRAL HOLES
... states, choose a cavity frequency that excites a resonance in each atom. Via this common excitation, a cavity photon can act as a ‘quantum wire’ over which the atoms can exchange optical coherence. Our qubits are stored on spins, however, and so we must use optical coherence to transfer spin coheren ...
