Multi-photon
entanglement: quantum foundations and technology
Entangled photons from spontaneous parametric
down-conversion have been an excellent platform for test of fundamental problems
in quantum mechanics and demonstration of quantum information processing
protocols. Previously, we have experimentally generated
six and eight-photon entanglement, five-photon ten-qubit hyper-entanglement,
Shor’s algorithm, anyonic simulation, loss-tolerant quantum coding etc. We aim
to further expand the photonic entanglement to larger scales towards practical
quantum computing with photonic qubits.
News:
We
used a four-quantum-bit quantum computer to solve a simple system of linear
equation. Check the preprint online http://arxiv.org/abs/1302.4310
