The time is right for multiphoton entangled states
In photonics, fundamental advances depend critically on continual improvements in device coupling, transmission losses, and material functionality. These requirements are especially critical in quantum photonics — the manipulation of quantum properties of light — where every photon is precious. A stunning example of how improved capabilities can facilitate basic discovery occurred in late 2015, when a few percent improvement in the efficiency of single-photon detectors enabled a definitive loophole-free demonstration of quantum nonlocality (1). On page 1176 of this issue, Reimer et al. (2) now show how a highly nonlinear optical glass can enable the on-chip generation of biphoton as well as multiphoton entangled qubits.

Abstract
In photonics, fundamental advances depend critically on continual improvements in device coupling, transmission losses, and material functionality. These requirements are especially critical in quantum photonics — the manipulation of quantum properties of light — where every photon is precious. A stunning example of how improved capabilities can facilitate basic discovery occurred in late 2015, when a few percent improvement in the efficiency of single-photon detectors enabled a definitive loophole-free demonstration of quantum nonlocality (1). On page 1176 of this issue, Reimer et al. (2) now show how a highly nonlinear optical glass can enable the on-chip generation of biphoton as well as multiphoton entangled qubits.
