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…
