648 Hilbert space dimensionality in a biphoton frequency comb
K. -C. Chang, X. Cheng, M. C. Sarihan +8
Qubit entanglement is a valuable resource for quantum information processing, where increasing its dimensionality provides a pathway towards higher capacity and increased error res…
Photon-efficient quantum cryptography with pulse-position modulation
Tian Zhong, Feihu Xu, Zheshen Zhang +7
The binary (one-bit-per-photon) encoding that most existing quantum key distribution (QKD) protocols employ puts a fundamental limit on their achievable key rates, especially under…
Nonlocal cancellation of dispersion in Franson interferometry
Tian Zhong, Franco N. C. Wong
Dispersion and its cancellation in entanglement-based nonlocal quantum measurements are of fundamental and practical interests. We report the first demonstration of cancellation of…
Entanglement's Benefit Survives an Entanglement-Breaking Channel
Zheshen Zhang, Maria Tengner, Tian Zhong +2
Entanglement is essential to many quantum information applications, but it is easily destroyed by quantum decoherence arising from interaction with the environment. We report the f…
Efficient single-spatial-mode periodically-poled KTiOPO_4 waveguide source for high-dimensional entanglement-based quantum key distribution
Tian Zhong, Franco N. C. Wong, Alessandro Restelli +1
We demonstrate generation of high-purity photon pairs at 1560 nm in a single spatial mode from a periodically-poled KTiOPO_4 (PPKTP) waveguide. With nearly lossless spectral filter…
