293. Möbius Resonators: Engineering Geometric Phase and Chirality in Twisted Microwave Cavities

Jeremy Bourhill

ANZOS | Photonics and Optics (ANZCOP)

Invited talk

Berry phases are geometric phases acquired by a system carried adiabatically around a closed loop, fixed entirely by the loop's geometry, as in the Aharonov-Bohm effect, where a charged particle's wavefunction shifts measurably on encircling a magnetic flux it never samples. We realise this physics in a tabletop platform: a free-space microwave cavity formed by twisting a triangular waveguide...

Erbium ions in silicon offer a promising route to telecom-compatible quantum photonic interfaces, combining optical transitions in the telecommunications band with access to electron and nuclear spin degrees of freedom. Because the relevant Er transitions arise from intra-4f orbitals that are shielded from the host environment, Er in silicon is expected to retain much of the optical coherence...

121. Engineering Phonon Isolation in SOI Superconducting Qubits for Radiation-Resilient Quantum Hardware

Contributed Oral

Superconducting qubits are highly susceptible to quasiparticle generation from background ionizing radiation, which produces energetic phonons capable of breaking Cooper pairs and inducing correlated errors. Following the observation of cosmic-ray–induced error bursts in large-scale superconducting qubit arrays [1], recent efforts have explored reducing the impact of ionizing radiation through...

220. Towards Programmable Photonic Linear Transforms via Cascaded LNOI Ring Resonators

Kok-Wei Bong (Monash University)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Photonic neural networks promise high-bandwidth, low-latency analogue computation, but most implementations rely on spatially multiplexed mesh architectures where an N-mode operation demands $O(N^2)$ individually controlled elements, placing significant demands on chip area and electrical interconnects. Electro-optically modulated ring resonators offer a compelling alternative by encoding...

792. Dissipation engineering in parametrically coupled Surface Acoustic Waves

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

We report parametrically activated coupling between surface-acoustic-wave (SAW) phonon modes, mediated by their mutual interaction with a flux-tunable superconducting SQUID array resonator. This work builds on the multimode platform employed in [1]. Exploiting the in-situ flux tunability of the array, we pump the SQUID array resonator at the frequency difference of two selected acoustic modes,...
