Entanglement, quantum discord, and the power of the quantum computer

Schematic illustration of the Quantum Computation with only a single pure qubit protocol (DQC1). A represents the pure qubit, B the maximally mixed state, obtained through maximal entanglement with the environment E. From left to right, initially B is entangled … Continue reading

Phase transition, entanglement and squeezing in a triple-well condensate

Occupational Husimi representation (left) and phase distribution (right) of the ground state for N = 30, Ω = −1, μ = 0 and self-collision parameter values: (a) χ=0, (b) χ=2 and (c) χ=3. In (b) we observe the squeezing in … Continue reading
