View article: Quantum-referenced spontaneous emission tomography
Quantum-referenced spontaneous emission tomography Open
We present a method of tomography in which photon pairs from a device-under-test (DUT) are experimentally characterised by quantum interference with a reference photon pair source; we call this quantum-referenced spontaneous emission tomog…

Integrate and scale: A source of spectrally separable photon pairs Open
Integrated photonics is a powerful contender in the race for a fault-tolerant quantum computer, claiming to be a platform capable of scaling to the necessary number of qubits. This necessitates the use of high-quality quantum states, which…

Quantum-Referenced Spontaneous Emission Tomography Open
We present a method of tomography that measures the joint spectral phase (JSP) of spontaneously emitted photon pairs originating from a largely uncharacterized ``target" source. We use quantum interference between our target source and a r…

Quantifying Hidden Nonlinear Noise in Integrated Photonics Open
We present experimental and simulated results to quantify the impact of nonlinear noise in integrated photonic devices relying on spontaneous four-wave mixing. Our results highlight the need for design rule adaptations to mitigate the othe…

Odderon Exchange from Elastic Scattering Differences between and Data at 1.96 TeV and from Forward Scattering Measurements Open
We describe an analysis comparing the pp[over ¯] elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV usi…

80 K vibration-free cooler for potential future Earth observation missions Open
A solution for a “vibration-free” Joule-Thomson cooler using a sorption compressor is presented to answer the needs of potential future Earth observation IR missions with low micro-vibration levels requirements from the European Space Agen…

Development of a 40 K to 80 K vibration-free cooler for future Earth observation missions Open
A solution for a sorption-based 40K to 80K Joule-Thomson cooler is presented to answer the needs of potential future Earth observation infrared missions with very low micro-vibration levels requirements from the European Space Agency. The …

Feasibility study of parallel conduction cooling of NbTi magnet and sample probe in a cryogen-free magnet system Open
The conduction cooling of both a 6 T superconducting magnet along with a sample probe in a parallel configuration is addressed in this work. A Gifford-McMahon (GM) cryocooler is directly cooling the NbTi magnet, which aims to be kept at 4 …

Gas gap heat switch for a cryogen-free magnet system Open
Cryogen-free superconducting magnet systems (CFMS) have become popular over the last two decades for the simple reason that the use of liquid helium is rather cumbersome and that helium is a scarce resource. Some available CFMS use a mecha…
