Quantum sensing: target detection with coherence

Shihan Sajeed;Bhashyam Balaji;Alex Kirillova;Thomas Jennewein

2023 IEEE International Conference on Consumer Electronics (ICCE)
Year: 2023 | Conference Paper |
We propose a novel approach for target detection based on quantum coherence. We exploit a time-bin quantum interferometer to create sequences of coherent optical pulses that are sent towards a target. The photons scattered off the target are then analyzed, and the observed coherence is used as a parameter to distinguish signal photons from noise photons. We confirm experimentally that coherence-ba...Show More

Testing Random-Detector-Efficiency Countermeasure in a Commercial System Reveals a Breakable Unrealistic Assumption

Anqi Huang;Shihan Sajeed;Poompong Chaiwongkhot;Mathilde Soucarros;Matthieu Legré;Vadim Makarov

IEEE Journal of Quantum Electronics
Year: 2016 | Volume: 52, Issue: 11 | Journal Article |
Cited by: Papers (63)
In the last decade, efforts have been made to reconcile theoretical security with realistic imperfect implementations of quantum key distribution. Implementable countermeasures are proposed to patch the discovered loopholes. However, certain countermeasures are not as robust as would be expected. In this paper, we present a concrete example of ID Quantique's random-detector-efficiency countermeasu...Show More

An approach to realize a quantum NOT gate through optical implementation

Shihan Sajeed;Z. H. Mozumder;A. Ahmed;S. M. Ullah;S. Rafique

2010 IEEE International Conference on Electro/Information Technology
Year: 2010 | Conference Paper |
Transverse modes of electromagnetic fields are proposed to be encoded as qubits for the implementation of a quantum NOT gate. The possibility of this encoding scheme was designed, simulated and verified through rigorous numerical analyses using the Beam propagation method. The proposed gate has the potential of being more compact and easily realizable than some other optical implementation proposa...Show More

An approach to realize a quantum Hadamard gate through optical implementation

Shihan Sajeed;A. Ahmed;S. M. Ullah;Z. H. Mozumder

2010 IEEE International Conference on Electro/Information Technology
Year: 2010 | Conference Paper |
Cited by: Papers (1)
Transverse modes of optical fields are proposed to be used as qubits for the implementation of quantum Hadamard gate. Mach-Zehnder Interferometer (MZI), phase shifter, y-junction beam splitters and other optical devices are utilized to realize a quantum Hadamard gate. The possibility of this encoding scheme was designed, simulated and verified through rigorous numerical analyses using the Beam pro...Show More

An experimental demonstration of quantum not gate: Transition from classical to quantum regime

Shihan Sajeed;A. F. M. Yusuf Haider

2010 IEEE International Conference on Electro/Information Technology
Year: 2010 | Conference Paper |
Path of a photon was considered to be used as qubit for implementing quantum NOT gate. An experimental setup was designed using a Mach-Zehnder interferometer constructed from simple optical devices such as He-Ne lasers, beam splitters, mirrors, attenuators etc. and quantum interference was utilized for multi photon case. A number of experiments were performed and the outcome of the experiment was ...Show More
