Invited talk

The global effort to develop quantum computers is driving the search for scalable methods to manufacture quantum chips and qubits. One promising pathway is to adapt the mature and highly scalable silicon manufacturing processes that underpin modern electronics, enabling quantum chips to be fabricated alongside conventional computer chips. This approach has generated substantial research...

Persistent spectral-holeburning is ubiquitous in optical spectroscopy, where it’s exploited for a myriad of applications in both classical and quantum signal processing, including laser stabilisation [1], real-time wideband spectral analysis [2], and quantum memory [3].
Prior to our work, however, spectral-holes in the microwave domain had only been observed to last microseconds or less [4,...

Nitrogen-vacancy (NV) centres in diamond can be used to detect radiofrequency (RF) signals through coupling of the RF magnetic field with the NV spins, combined with optical readout of the spin state. The sensitivity of such RF detectors has so far been mainly studied in terms of magnetic field sensitivity, which is relevant when the RF signal is generated by a near-field source. However, for...

Recent experimental results have shown Au nanoparticles (NP) in liquid Ga (liq-Ga) are excellent photocatalysts for benzyl alcohol conversion to benzaldehyde. When the Au NPs are placed in liq-Ga they develop an ultra-thin amorphous-GaOx (a-GaOx) skin/film which is expected to play an important role in the photoreaction. Therefore, understanding the reaction mechanism requires atomic level...

525. Engineered Erbium Emitters in Calcium Fluoride with Ion Co-Implantation

Communicating quantum information beyond the order of metres requires minimally-lossy avenues of transmission. Optical fibres - internationally deployed as a backbone of modern, classical telecommunications - present the opportunity for such quantum information to be photonically networked with astonishingly low losses capable of reaching -0.091 dB/km within the telecommunications C-band...
