We propose an enhanced discrimination measurement for tripartite 3-dimensional entangled states in order to improve the discernible number of orthogonal entangled states. The scheme suggests 3-dimensional Bell state measurement by exploiting composite two 3-dimensional state measurement setups. The setup relies on state-of-the-art techniques, a multi-port interferometer and nondestructive photon number measurements that are used for the post-selection of suitable ensembles. With this scheme… Expand

Efficient High-Dimensional Quantum Key Distribution with Hybrid Encoding
TLDR
It is shown that the proposed feasible protocol has improved the secret key rate with much sophistication compared to the previous 2-dimensional protocol known as the detector-device-independent QKD. Expand
Device Independent Quantum Key Distribution Using Three-Party Pseudo-Telepathy
TLDR
This work presents a simple proposal that exploits the idea of multi-party pseudo-telepathy game to certify device independent security and discusses the relative advantages of the protocol. Expand
Semi-device-independent multiparty quantum key distribution in the asymptotic limit
TLDR
This analysis provides an asymptotic secret key rate of the multiparty QKD under the restriction that successive trials are completely independent and shows that side channel attacks are prevented in this analysis. Expand
A quantum number theory
We employ an algebraic procedure based on quantum mechanics to propose a ‘quantum number theory’ (QNT) as a possible extension of the ‘classical number theory’. We built our QNT by defining pureExpand

Large-alphabet quantum key distribution using energy-time entangled bipartite States.
TLDR
Binned, high-resolution timing measurements are used to generate a large-alphabet key with over 10 bits of information per photon pair, albeit with large noise. Expand
Measurement-device-independent quantum key distribution.
TLDR
The results show that long-distance quantum cryptography over say 200 km will remain secure even with seriously flawed detectors, and the key generation rate is many orders of magnitude higher than that based on full device independent QKD. Expand

N-dimensional measurement-device-independent quantum key distribution with N + 1 un-characterized sources: zero quantum-bit-error-rate case
TLDR
Only assuming that the checking state is a superposition of other N sources, it is shown that the protocol is secure in zero quantum-bit-error-rate case, suggesting possibility of the protocol. Expand
Coherent ultrafast measurement of time-bin encoded photons.

A tomographically complete set of time-bin qubit projective measurements is demonstrated and the fidelity of operations is sufficiently high to violate the Clauser-Horne-Shimony-Holt-Bell inequality by more than 6 standard deviations. Expand
Qudit-Teleportation for photons with linear optics
TLDR
This work shows how to teleport a “qudit”, i.e. a superposition of an arbitrary number d of distinguishable states present in the orbital angular momentum of a single photon using d beam splitters and d additional entangled photons. Expand
