Scalable entanglement distribution using encoded hybrid repeater chains
Stav Haldar, Saikat Guha, Don Towsley +1
Long-distance entanglement distribution requires error correction protocols to compensate for qubit decoherence in quantum memories and noise introduced during entanglement swappin…
Quantum-enhanced quickest change detection of transmission loss
Saikat Guha, Tiju Cherian John, Zihao Gong +1
Augmenting a train of bright phase-modulated laser-light pulses of a coherent communications system with infinitesimally small quantum photons per pulse -- entangled across several…
Multiplexed bi-layered realization of fault-tolerant quantum computation over optically networked trapped-ion modules
Nitish K. Chandra, Saikat Guha, Kaushik P. Seshadreesan
We study an architecture for fault-tolerant measurement-based quantum computation (FT-MBQC) over optically-networked trapped-ion modules. The architecture is implemented with a fin…
Utilizing probabilistic entanglement between sensors in quantum networks
Emily A. Van Milligen, Christos N. Gagatsos, Eneet Kaur +2
One of the most promising applications of quantum networks is entanglement assisted sensing. The field of quantum metrology exploits quantum correlations to improve the precision b…
Bipartite entanglement of noisy stabilizer states through the lens of stabilizer codes
Kenneth Goodenough, Aqil Sajjad, Eneet Kaur +2
Stabilizer states are a prime resource for a number of applications in quantum information science, such as secret-sharing and measurement-based quantum computation. This motivates…
Quantum Network Tomography
Matheus Guedes de Andrade, Jake Navas, Saikat Guha +4
Errors are the fundamental barrier to the development of quantum systems. Quantum networks are complex systems formed by the interconnection of multiple components and suffer from…
Lower bounds on bipartite entanglement in noisy graph states
Aqil Sajjad, Eneet Kaur, Kenneth Goodenough +2
Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is…
Gaussian Boson Sampling to Accelerate NP-Complete Vertex-Minor Graph Classification
Mushkan Sureka, Saikat Guha
Gaussian Boson Sampling (GBS) generate random samples of photon-click patterns from a class of probability distributions that are hard for a classical computer to sample from. Desp…
All-photonic GKP-qubit repeater using analog-information-assisted multiplexed entanglement ranking
Filip Rozpędek, Kaushik P. Seshadreesan, Paul Polakos +2
Long distance quantum communication will require the use of quantum repeaters to overcome the exponential attenuation of signal with distance. One class of such repeaters utilizes…
On the Capacity Region of Bipartite and Tripartite Entanglement Switching
Gayane Vardoyan, Philippe Nain, Saikat Guha +1
We study a quantum entanglement distribution switch serving a set of users in a star topology with equal-length links. The quantum switch, much like a quantum repeater, can perform…
