Distributed g(2) Retrieval with Atomic Clocks: Eliminating Conventional Sync Protocols
Md Mehdi Hassan, Jacob E. Humberd, Mohmad Junaid Ul Haq +3
We demonstrate a method to measure coincidences between polarization-entangled photons distributed to distant locations, eliminating traditional synchronization by employing a comp…
Practical Quantum Clock Synchronization Using Weak Coherent Pulses
Noah Crum, Md Mehdi Hassan, George Siopsis
Establishing and maintaining a common time reference across spatially separated devices is a prerequisite for networked quantum experiments and secure communications. Classical two…
Reconfigurable Four-Photon Interference among Three Nodes on a Field Deployed Metropolitan Fiber Network
Kazi Reaz, Md Mehdi Hassan, Jacob E. Humberd +7
Advanced quantum networking protocols beyond bi-photon, point-to-point links rely critically on the ability to perform multi-photon interference across multiple nodes under realist…
Mode Distinguishability in Multi-photon Interference
Noah Crum, Md Mehdi Hassan, Adrien Green +1
The Hong-Ou-Mandel (HOM) effect is a quintessential process in various quantum information technologies and quantum optics applications. In this work, we investigate multi-photon i…
Experimental decoy-state asymmetric measurement-device-independent quantum key distribution over a turbulent high-loss channel
Kazi Reaz, Md Mehdi Hassan, Adrien Green +2
Real-world BB84 Quantum Key Distribution (QKD) systems utilize imperfect devices that introduce vulnerabilities to their security, known as side-channel attacks. Measurement-Device…
Experimental free-space quantum key distribution over a turbulent high-loss channel
Md Mehdi Hassan, Kazi Reaz, Adrien Green +2
Free-space quantum cryptography plays an integral role in realizing a global-scale quantum internet system. Compared to fiber-based communication networks, free-space networks expe…
