Entangling entanglement: coupling frequency and polarization of biphotons on demand
Arash Riazi, Eric Y. Zhu, Dan Xu +1
Quantum information is often carried in the frequency and polarization degrees of freedom (DoFs) in single photons and entangled photons. We demonstrate a new approach to couple an…
Telecom-band Hyperentangled Photon Pairs from a Fiber-based Source
Changjia Chen, Calvin Xu, Arash Riazi +6
Hyperentanglement, the simultaneous and independent entanglement of quantum particles in multiple degrees of freedom, is a powerful resource that can be harnessed for efficient qua…
Machine-Learning-Derived Entanglement Witnesses
Alexander C. B. Greenwood, Larry T. H. Wu, Eric Y. Zhu +2
In this work, we show a correspondence between linear support vector machines (SVMs) and entanglement witnesses, and use this correspondence to generate entanglement witnesses for…
Real-time ultrasound sensing with a mode-optimized photonic crystal slab
Eric Y. Zhu, Maria Charles-Herrera, Cory Rewcastle +3
Integrated photonic sensors can provide large scale, flexible detection schemes. Photonic crystal slabs (PCS) offer a miniaturized platform for wideband, sensitive ultrasound detec…
Broadband Fiber-based Entangled Photon Pair Source at Telecom O-band
Changjia Chen, Calvin Xu, Arash Riazi +4
In this letter, we report a polarization-entangled photon-pair source based on type-II spontaneous parametric down conversion at telecom O-band in periodically poled silica fiber (…
Recovering the full dimensionality of hyperentanglement in collinear photon pairs
Changjia Chen, Arash Riazi, Eric Y. Zhu +1
Exploiting hyperentanglement of photon pairs, that is, simultaneous entanglement in multiple degrees of freedom(DOFs), increases the dimensionality of Hilbert spaces for quantum in…
