ANZOS | Photonics and Optics (ANZCOP)

Invited talk

Portable optical-frequency atomic clocks have reached a maturity level that allows them to be used outside of a laboratory setting. Specifically, portable optical clocks have been demonstrated in sea trials [1], in urban deployments [2], and clock sub-systems have even been operated on-orbit [3]. Portable optical clocks will be integral in advancing fundamental physics including tests of...

Contributed Oral

Superconducting circuits are a leading platform for quantum computing due to their strong coupling to microwave photons, highly customizable design, and long coherence times. The fluxonium qubit in particular has recently shown promise, demonstrating millisecond coherence and high anharmonicity, leading to impressive single and two-qubit control fidelity. However, further improvement in qubit...

665. Dynamic stimulated emission for deterministic addition and subtraction of propagating photons

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Photon addition and subtraction are essential non-Gaussian processes in quantum optics, where conventional methods rely on the use of linear optics and number-resolving detection often suffer from low success probability. Here, we introduce the concept of dynamic stimulated emission, whereby a quantum emitter undergoes stimulated emission with a time-dependent coupling. We show that, for both...

692. End-to-end fault-tolerant compilation and resource estimation of Shor's algorithm

Contributed Oral

Quantum factoring is one of the most promising applications of quantum computing with practical real-world implications. Since its discovery by Peter Shor, researchers have reduced the memory requirements and optimised the gate counts of arithmetic subroutines for its implementation. Several notable advancements over the past year have brought the the memory cost of factoring a 2048 bit RSA...
