A Unified Quantum Interferometric Framework for Interaction-Free Measurement and Delayed-Choice Experiments
Hitesh Awasthi, Sandeep Mishra, Anirban Pathak
A theoretical unified interferometric framework is developed for interaction-free measurement (IFM) and delayed-choice (DC) experiments. The proposed model leads to a quantum circu…
On the generic structures of the protocols for quantum auction and quantum summation and their relation
Kabir Sandhu, Sandeep Mishra, Anirban Pathak
Secure multi-party computation (SMC) addresses the problem of jointly computing global functions of private inputs while revealing minimal information about individual data. Two pr…
Finite key analysis of experimentally realized practical COW-QKD protocol
Neha Pathania, Sandeep Mishra, Anirban Pathak
An experimental implementation of the Coherent One-Way Quantum Key Distribution (COW-QKD) protocol is reported under realistic conditions, and a clean and easy-to-use framework for…
Frequency drift corrected ultra-stable laser through phase-coherent fiber producing a quantum channel
Stanley Johnson, Sandeep Mishra, Anirban Pathak +1
Phase coherent fibers (PCF) are essential to distribute nearly monochromatic photons, ultra-stable in their frequency and phases, which have demanding requirements for state-of-the…
Experimental implementation of distributed phase reference quantum key distribution protocols
Satish Kumar, Priya Malpani, Britant +2
Quantum cryptography is now considered as a promising technology due to its promise of unconditional security. In recent years, rigorous work is being done for the experimental rea…
Partial Loopholes Free Device Independent Quantum Random Number Generator Using IBM's Quantum Computers
Abhishek Yadav, Sandeep Mishra, Anirban Pathak
Random numbers form an intrinsic part of modern day computing with applications in a wide variety of fields. But due to their limitations, the use of pseudo random number generator…
Open quantum system dynamics of -states: Entanglement sudden death and sudden birth
Nikhitha Nunavath, Sandeep Mishra, Anirban Pathak
The origin of disentanglement for two specific sub-classes of -states namely maximally nonlocal mixed states (MNMSs) and maximally entangled mixed states (MEMSs) is investigated…
Anonymous voting scheme using quantum assisted blockchain
Sandeep Mishra, Kishore Thapliyal, S Krish Rewanth +2
Voting forms the most important tool for arriving at a decision in any institution. The changing needs of the civilization currently demands a practical yet secure electronic votin…
Quantum and Semi-Quantum Lottery: Strategies and Advantages
Sandeep Mishra, Anirban Pathak
Lottery is a game in which multiple players take chances in the hope of getting some rewards in cash or kind. In addition, from the time of the early civilizations, lottery has als…
A Comprehensive Review of Quantum Random Number Generators: Concepts, Classification and the Origin of Randomness
Vaisakh Mannalath, Sandeep Mishra, Anirban Pathak
Random numbers are central to cryptography and various other tasks. The intrinsic probabilistic nature of quantum mechanics has allowed us to construct a large number of quantum ra…
Quantum anonymous veto: A set of new protocols
Sandeep Mishra, Kishore Thapliyal, Abhishek Parakh +1
We propose a set of protocols for quantum anonymous veto (QAV) broadly categorized under the probabilistic, iterative, and deterministic schemes. The schemes are based upon differe…
Attainable and usable coherence in X states over Markovian and non-Markovian channels
Sandeep Mishra, Kishore Thapliyal, Anirban Pathak
The relations between the resource theoretic measures of quantum coherence are rigorously investigated for various Markovian and non-Markovian channels for the two-qubit states…
