When AI meets quantum information: A comprehensive review
Min Chen, Yu Gan, Xin Jin +15
Artificial intelligence (AI) and quantum information (QI) are rapidly co-evolving. AI is becoming a practical tool for learning, designing, controlling, and verifying quantum syste…
Sequential vs. Synchronized Entanglement Swapping: QKD Secret-Key Rate under Optimized Link-Layer Control
Priyam Srivastava, Akshat R. Sabavat, Siddharth Jain +6
Quantum repeater chains build long-distance entanglement for quantum key distribution (QKD) by creating pairs on short links and joining them through entanglement swapping. Because…
Variational Joint Magnetometry and Gradiometry on Dipolar Spin Chains
Priyam Srivastava, Xin Jin, Junyu Liu +4
Estimating a uniform magnetic field B0 and its spatial gradient g on a dipolar-coupled spin chain calls for a multiparameter figure of merit. The GHZ state, optimal for single-para…
Four Generations of Quantum Biomedical Sensors
Xin Jin, Priyam Srivastava, Ronghe Wang +7
Quantum sensing technologies offer transformative potential for ultra-sensitive biomedical sensing, yet their clinical translation remains constrained by classical noise limits and…
Variational Probe and Measurement Optimization for Structured Phase Estimation
Priyam Srivastava, Vivek Kumar, Gurudev Dutt +1
We present a proof-of-principle study of variational quantum sensing for estimating a structured linear function of local phase parameters, in which each qubit in a spin-1/2 array…
