Contributed Oral

Distributing entanglement is pivotal for sharing quantum information over long distances via entanglement swapping protocols, enabling applications in communication, metrology, and computing. Entanglement swapping protocols consist of performing a Bell-state measurement (BSM) at a central station to share entanglement between two separate parties. Fully-optical entanglement swapping protocols...

536. Continuous variable quantum key distribution through a free space fading channel with minimal information leakage

AIP | Quantum Science and Technology (QST)

Contributed Oral

Quantum key distribution (CVQKD) enables the distribution of provably secure keys for cryptography by exploiting fundamental principles of quantum mechanics. QKD protocols can be broadly classified as either discrete-variable QKD, encoding information in discrete quantum states, or continuous-variable (CV) QKD, which encodes information in the continuous amplitude and phase quadratures and...

Contributed Oral

Continuous physical-layer security monitoring is essential for practical quantum key distribution (QKD) systems, as device imperfections and attacks may compromise the fundamental assumptions underlying ideal security proofs. In recent years, machine-learning-based anomaly detection methods have demonstrated strong capabilities in multi-domain fault and attack localization. However,...

473. Low-Latency Direct Secure Quantum Communication Using Squeezed States

Dr Jiayi Qin (The Australian National University)

08/12/2026, 17:15

AIP | Quantum Science and Technology (QST)

Contributed Oral

Quantum communication exploits the properties of quantum states to enable secure information transfer. Over the past several decades, quantum key distribution has become the dominant approach to quantum-secure communication, where a shared secret key is first established before encrypted communication takes place. An alternative approach is direct quantum communication, in which the message...

364. Distributed quantum anonymous voting using novel Gaussian direct secure communications

Nicholas Zaunders (University of Queensland)

08/12/2026, 17:30

AIP | Quantum Science and Technology (QST)

Contributed Oral

Voting protocols using entangled quantum states as ballots have been proposed as a solution to the problem of information-theoretically secure and private voting, something which is thus far unobtainable through classical schemes alone. However, quantum voting protocols are frequently impractically complex, resource-intensive and have poor robustness to noise, loss, or adversarial behaviour....

514. Toward Logical Q-PUFs for Trustworthy Quantum Information Systems

Behnam Tonekaboni (Infleqtion Australia)

AIP | Quantum Science and Technology (QST)

Contributed Oral

Future quantum information systems will increasingly rely on remote processors, distributed data, and hybrid quantum-classical workflows. As access to quantum hardware moves from dedicated laboratories to cloud platforms and shared infrastructure, trust becomes both a scientific and engineering challenge: how can a user know that a remote quantum processor is the device it claims to be, and...
