816. Designing continuous-variable quantum networks

Josephine Dias (University of Queensland)

ANZOS | Photonics and Optics (ANZCOP)

Invited talk

A future quantum internet will enable the long-distance distribution of entanglement, supporting provably secure communication, networked quantum computing, and enhanced sensing. Realising such a network is fundamentally challenging because quantum information cannot be copied or amplified in the same way as classical signals. In this talk, I will present my work on overcoming these...

Entanglement distribution over lossy quantum channels is a fundamental challenge in quantum communication, where channel loss and decoherence progressively degrade the quality of shared entangled states. Noiseless linear amplification (NLA) offers a probabilistic but heralded solution to this problem, enabling entanglement distillation without violating the no-cloning theorem. However, the...

744. Answering Counting Queries with Differential Privacy on a Quantum Computer

Contributed Oral

Differential privacy is the de-facto standard for privacy-preserving data analysis, and recently it has been extended to the quantum realm. We study how to answer counting queries on quantum-encoded datasets while preserving privacy. A counting query asks for the fraction of records satisfying a Boolean predicate, such as '*How many people in the dataset are students and within the age...

222. Quantum-Enhanced Multi-Parameter Sensing in a Single Mode

ANZOS | Quantum and Atom Optics (ANZCOP QAO)

Contributed Oral

Precision metrology underpins scientific and technological advancements. Quantum metrology offers a pathway to surpass classical sensing limits by leveraging both quantum states and measurement strategies. However, measuring multiple incompatible parameters suffers from a fundamental limit, exemplified by Heisenberg's uncertainty principle for two non-commuting observables, such as position...
