On the Connection Between Quantum Pseudorandomness and Quantum Hardware Assumptions
Mina Doosti, Niraj Kumar, Elham Kashefi +1
This paper, for the first time, addresses the questions related to the connections between the quantum pseudorandomness and quantum hardware assumptions, specifically quantum physi…
Quantum Lock: A Provable Quantum Communication Advantage
Kaushik Chakraborty, Mina Doosti, Yao Ma +3
Physical unclonable functions(PUFs) provide a unique fingerprint to a physical entity by exploiting the inherent physical randomness. Gao et al. discussed the vulnerability of most…
QEnclave -- A practical solution for secure quantum cloud computing
Yao Ma, Elham Kashefi, Myrto Arapinis +2
We introduce a secure hardware device named a QEnclave that can secure the remote execution of quantum operations while only using classical controls. This device extends to quantu…
Entanglement Distribution in Multi-Platform Buffered-Router-Assisted Frequency-Multiplexed Automated Repeater Chains
Mohsen Falamarzi Askarani, Kaushik Chakraborty, Gustavo Castro do Amaral
Realization of a globe-spanning quantum network is a current worldwide goal, where near and long term implementations will benefit from connectivity between platforms optimized for…
Designing Quantum Networks Using Preexisting Infrastructure
Julian Rabbie, Kaushik Chakraborty, Guus Avis +1
We consider the problem of deploying a quantum network on an existing fiber infrastructure, where quantum repeaters and end nodes can only be housed at specific locations. We propo…
Entanglement Distribution in a Quantum Network, a Multi-Commodity Flow-Based Approach
Kaushik Chakraborty, David Elkouss, Bruno Rijsman +1
We consider the problem of optimising the achievable EPR-pair distribution rate between multiple source-destination pairs in a quantum internet, where the repeaters may perform a p…
Distributed Routing in a Quantum Internet
Kaushik Chakraborty, Filip Rozpedek, Axel Dahlberg +1
We develop new routing algorithms for a quantum network with noisy quantum devices such that each can store a small number of qubits. We thereby consider two models for the operati…
Improved and Formal Proposal for Device Independent Quantum Private Query
Jyotirmoy Basak, Kaushik Chakraborty, Arpita Maitra +1
In this paper, we propose a novel Quantum Private Query (QPQ) scheme with full Device-Independent certification. To the best of our knowledge, this is the first time we provide suc…
Robust Relativistic Bit Commitment
Kaushik Chakraborty, André Chailloux, Anthony Leverrier
Relativistic cryptography exploits the fact that no information can travel faster than the speed of light in order to obtain security guarantees that cannot be achieved from the la…
Practical Position-Based Quantum Cryptography
Kaushik Chakraborty, Anthony Leverrier
We study a general family of quantum protocols for position verification and present a new class of attacks based on the Clifford hierarchy. These attacks outperform current strate…
Arbitrarily long relativistic bit commitment
Kaushik Chakraborty, André Chailloux, Anthony Leverrier
We consider the recent relativistic bit commitment protocol introduced by Lunghi et al. [Phys. Rev. Lett. 2015] and present a new security analysis against classical attacks. In pa…
Improved quantum test for linearity of a Boolean function
Kaushik Chakraborty, Subhamoy Maitra
Let a Boolean function be available as a black-box (oracle) and one likes to devise an algorithm to test whether it has certain property or it is -far from having that property.…
