Silicon colour centres are an emerging quantum information platform with technological appeal: they emit in or near the optical telecommunications bands, host long coherence spin qubits, and integrate with silicon photonic and electronic circuits for scalable on-chip devices. Potential applications include single-photon sources and quantum repeaters for quantum networks, and resource-state...

The realization of long-distance quantum communication will depend critically on quantum repeater nodes that incorporate robust and scalable quantum memories. To be practical, these memories must meet specific operational requirements. One promising candidate for such devices is the atomic warm vapor system, operating under the regime of electromagnetically induced transparency (EIT). These...

Recent advances in quantum technology have highlighted the need for long-distance quantum communication in order to enable technologies such as quantum key distribution, very-long-baseline interferometry, and distributed quantum computing. Fiber attenuation limits optical fiber links to hundreds of kilometers, while present day satellite links are limited to line-of-sight connections of...

We present our progress in developing a surface ion trap system designed for quantum information processing with barium ions. Ba⁺ ions are among the most promising qubit candidates due to their long-lived quantum states and visible-wavelength optical transitions, allowing the use of commercial optics and waveguide-based modulators for individual qubit control. Our system features a Sandia...

Condensed matter systems such as superfluids can simulate phenomena in every major area of physics, from gravitational to cosmological to high-energy physics, including an analog for quark confinement known as “vortex molecules” (Eto, Ikeno & Nitta, 2020). On the other hand, in the last twenty years the field of Hydrodynamic Quantum Analogs (HQA), which studies the walking droplet pilot wave...

Problem: Indeterminacy is a foundational principle of quantum physics. The fact that pure quantum systems possess properties with no definite single sharp value is a fundamental expression of this quantum indeterminacy. For example, an electron within an atom possesses no definite value of linear momentum. Although, in isolation, indeterminacy is not inherently problematic, there is...
