Spooky action at a global distance: analysis of space-based entanglement distribution for the quantum internet
Sumeet Khatri, Anthony J. Brady, Renée A. Desporte +2
Recent experimental breakthroughs in satellite quantum communications have opened up the possibility of creating a global quantum internet using satellite links. This approach appe…
Second-order coding rates for key distillation in quantum key distribution
Sumeet Khatri, Eneet Kaur, Saikat Guha +1
The security of quantum key distribution has traditionally been analyzed in either the asymptotic or non-asymptotic regimes. In this paper, we provide a bridge between these two re…
Noise Resilience of Variational Quantum Compiling
Kunal Sharma, Sumeet Khatri, M. Cerezo +1
Variational hybrid quantum-classical algorithms (VHQCAs) are near-term algorithms that leverage classical optimization to minimize a cost function, which is efficiently evaluated o…
Practical figures of merit and thresholds for entanglement distribution in quantum networks
Sumeet Khatri, Corey T. Matyas, Aliza U. Siddiqui +1
Before global-scale quantum networks become operational, it is important to consider how to evaluate their performance so that they can be built to achieve the desired performance.…
Extendibility of bosonic Gaussian states
Ludovico Lami, Sumeet Khatri, Gerardo Adesso +1
Extendibility of bosonic Gaussian states is a key issue in continuous-variable quantum information. We show that a bosonic Gaussian state is -extendible if and only if it has a…
Information-theoretic aspects of the generalized amplitude damping channel
Sumeet Khatri, Kunal Sharma, Mark M. Wilde
The generalized amplitude damping channel (GADC) is one of the sources of noise in superconducting-circuit-based quantum computing. It can be viewed as the qubit analogue of the bo…
