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 with E (purple bar). The protocol is then executed and A, although not directly entangled with B, gets entangled with the pair BE as the Quantum Discord between A and B increases. Phys. Rev. A 84, 012313 (2011).
