Strength in Numbers
2015
Popular social and e-commerce sites increasingly rely on crowd computing to rate and rank content, users, products and businesses. Today, attackers who create fake (Sybil) identities can easily tamper with these computations. Existing defenses that …

Routing entanglement in the quantum internet
2019 · npj Quantum Information
Abstract Remote quantum entanglement can enable numerous applications including distributed quantum computation, secure communication, and precision sensing. We consider how a quantum network—nodes equipped with limited quantum processing capabilities connected via lossy optical links—can distribute …

On the Analysis of a Multipartite Entanglement Distribution Switch
2020 · Proceedings of the ACM on Measurement and Analysis of Computing Systems
We study a quantum switch that distributes maximally entangled multipartite states to sets of users. The entanglement switching process requires two steps: first, each user attempts to generate bipartite entanglement between itself and the switch; …

On the Stochastic Analysis of a Quantum Entanglement Distribution Switch
2021 · IEEE Transactions on Quantum Engineering
In this article, we study a quantum entanglement distribution switch that serves$k$users in a star topology. We model variants of the system as continuous-time Markov chains and obtain expressions for switch capacity, expected number of …

Demonstration of quantum advantage by a joint detection receiver for optical communications using quantum belief propagation on a trapped-ion device
2021 · arXiv (Cornell University)
Demonstrations of quantum advantage have largely focused on computational speedups and on quantum simulation of many-body physics, limited by fidelity and capability of current devices. Discriminating laser-pulse-modulated classical-communication codewords at the minimum allowable probability of …

Entanglement-Assisted Coding for Arbitrary Linear Computations Over a Quantum MAC
2025 · arXiv (Cornell University)
We study a linear computation problem over a quantum multiple access channel (LC-QMAC), where $S$ servers share an entangled state and separately store classical data streams $W_1,\cdots, W_S$ over a finite field $\mathbb{F}_d$. A user …
