Quantum-Optimized Reconstruction of Ketone Dynamics from Fabry-Pérot Optical Breath Measurements
Introduction: Diabetes management depends on measurements that are often invasive, intermittent, or expensive. Acetone in exhaled breath is linked to ketone metabolism and can be measured optically, but a breath spectrum is not itself a metabolic state: the clinically meaningful quantities—blood β-hydroxybutyrate (BHB), acetoacetate, acetone, and t... read more

Optimizing Quantum State Transfer in Sparse Networks
A quantum network can be modeled as a graph, with vertices representing sites that can hold an excitation and edges representing couplings between those sites. An excitation may be spread across several sites in a superposition. As the state evolves, probability amplitudes combine through interference, changing where the excitation is likely to ... read more

Shrinking Quantum Key Distribution onto a Chip
Quantum key distribution (QKD) allows two parties to establish a shared secret key while detecting whether an eavesdropper has intercepted the communication. In the BB84 protocol, information is encoded using four quantum states divided between two measurement bases. Because measuring a quantum state can disturb it, an eavesdropper attempting to in... read more

Optimizing Angular Multiplexing for Holograph Data Storage
Holographic data storage involves storing many two-dimensional images inside a certain volume filled with photopolymer by slightly tilting the reference beam. It presents a good alternative to hard drives, as it offers both high capacity and access rates. One of the main techniques this is achieved by is angular multiplexing. Conventional angula... read more
