Spin-Dependent Charge-State Conversion in NV Ensembles Mediated by Electron Tunneling
Neil B. Manson, Morgan Hedges, Michael S. J. Barson +3
The nitrogen-vacancy (NV) center in diamond enables optical initialization and readout of its electronic spin, forming the basis of a wide range of quantum sensing and metrology ap…
Search for a solar-bound axion halo using the Global Network of Optical Magnetometers for Exotic physics searches
Tatum Z. Wilson, Derek F. Jackson Kimball, Samer Afach +50
We report on a search for a gravitationally bound solar axion halo using data from the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), a worldwide arra…
Pulsed Dual-axis Alkali-metal-noble-gas Comagnetometer
Jingyao Wang, Junyi Lee, Hudson Loughlin +2
Alkali-metal-noble-gas comagnetometers are precision probes well-suited for tests of fundamental physics and inertial rotation sensing, combining high sensitivity of the spin-excha…
Dual axis atomic magnetometer and gyroscope enabled by nuclear spin perturbation
Morgan Hedges, Ankit Papneja, Karun Paul +1
Alkali-noble-gas comagnetometers have become an essential tool for tests of fundamental physics and offer a compact platform for precision gyroscopy. They are, however, limited by…
Progress towards efficient 4-level photon echo memories
James Stuart, Kieran Smith, Morgan Hedges +2
Quantum memories could benefit many devices in quantum information processing. For a quantum to be useful in real-world applications, the quantum memory must have a high recall eff…
A Multi-Messenger Search for Exotic Field Emission with a Global Magnetometer Network
Sami S. Khamis, Ibrahim A. Sulai, Paul Hamilton +38
Quantum sensor networks in combination with traditional astronomical observations are emerging as a novel modality for multi-messenger astronomy. Here we develop a generic analysis…
What can a GNOME do? Search targets for the Global Network of Optical Magnetometers for Exotic physics searches
S. Afach, D. Aybas Tumturk, H. Bekker +50
Numerous observations suggest that there exist undiscovered beyond-the-Standard-Model particles and fields. Because of their unknown nature, these exotic particles and fields could…
Optimising the Efficiency of a Quantum Memory based on Rephased Amplified Spontaneous Emission
Charlotte K. Duda, Kate R. Ferguson, Rose L. Ahlefeldt +2
We studied the recall efficiency as a function of optical depth of rephased amplified spontaneous emission (RASE), a protocol for generating entangled light. The experiments were p…
Initialisation protocol for efficient quantum memories using resolved hyperfine structure
James Stuart, Morgan Hedges, Rose Ahlefeldt +1
We describe a quantum memory spectral preparation strategy that maximises memory efficiency and bandwidth in materials such as 167 Er3+:Y2SiO5 in a high field regime, where the hyp…
Search for topological defect dark matter with a global network of optical magnetometers
Samer Afach, Ben C. Buchler, Dmitry Budker +46
Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that…
NV- - N+ pair centre in 1b diamond
Neil B. Manson, Morgan Hedges, Michael S +6
The study establishes that the degree of optically induced spin polarization that can be achieved for NVin 1b diamond is limited by the concentration of single substitutional…
Coherence time of over a second in a telecom-compatible quantum memory storage material
Miloš Rančić, Morgan P. Hedges, Rose L. Ahlefeldt +1
Quantum memories for light will be essential elements in future long-range quantum communication networks. These memories operate by reversibly mapping the quantum state of light o…
Efficient and long-lived Zeeman-sublevel atomic population storage in an erbium-doped glass fiber
Erhan Saglamyurek, Thomas Lutz, Lucile Veissier +4
Long-lived population storage in optically pumped levels of rare-earth ions doped into solids, referred to as persistent spectral hole burning, is of significant fundamental and te…
Spectral multiplexing for scalable quantum photonics using an atomic frequency comb quantum memory and feed-forward control
Neil Sinclair, Erhan Saglamyurek, Hassan Mallahzadeh +8
Future multi-photon applications of quantum optics and quantum information science require quantum memories that simultaneously store many photon states, each encoded into a differ…
Photon echo quantum memories in inhomogeneously broadened two level atoms
D. L. McAuslan, P. M. Ledingham, W. R. Naylor +4
Here we propose a solid-state quantum memory that does not require spectral holeburning, instead using strong rephasing pulses like traditional photon echo techniques. The memory u…
