    • A team of engineering geniuses from the University of Bristol, England has developed the world’s first re-programmable, multi-purpose quantum photonic computer chip that relies on quantum entanglement to perform calculations.

      With multiple waveguide channels (made from standard silicon dioxide), and eight electrodes (see image above), the silicon chip is capable of repeatedly entangling photons. Depending on how the electrodes are programmed, different quantum states can be produced. The end result is two qubits that can be used to perform quantum computing — and unlike D-Wave’s 128-qubit processor (well, depending on who you ask) this is real quantum computing.

    • We know that entanglement can be used for very effective encryption, but beyond that it’s mostly guesswork. There’s general agreement that qubits should allow for faster computation of very complex numbers — think biological processes and weather systems — and early work by Google suggests that pattern recognition might also be a strength of qubits.
