Squeezed light from a nanophotonic molecule
Squeezed light sources are a fundamental building block of photonic technologies for quantum information processing. Squeezing is an essential resource for quantum sensing and a wide range of quantum computing algorithms. Recently, much effort has […]
Qubits Could Act as Sensitive Dark Matter Detectors - A. Dixit/University of Chicago
Qubits could act as sensitive Dark Matter detectors
A detector made from superconducting qubits could allow researchers to search for dark matter particles 1000 times faster than other techniques can. Dark matter particles, such as axions and hidden photons, are theorized to occasionally […]

Startup Atomionics raises S$2.5m
Atomionics, a Singapore-based startup which develops quantum sensors that enable navigation without GPS, has raised S$2.5 million in seed funding led by Wavemaker Partners, in partnership with SGInnovate and Cap Vista. Atomionics was founded in […]
General procedure for identifying hyperfine parameters of 13C nuclear spins
Deep learning enhanced individual nuclear-spin detection
The detection of nuclear spins using individual electron spins has enabled diverse opportunities in quantum sensing and quantum information processing. Proof-of-principle experiments have demonstrated atomic-scale imaging of nuclear-spin samples and controlled multi-qubit registers. However, to […]
Schematic description of the single-qubit experiment for detection of a signal.
Optimal control for quantum detectors
Quantum systems are promising candidates for sensing of weak signals as they can be highly sensitive to external perturbations, thus providing excellent performance when estimating parameters of external fields. However, when trying to detect weak […]
Building resilient cities with quantum sensors: an interview with Dr Simon Bennett
Our everyday reliance on navigation systems is often hugely underestimated, as is the dependence of services on Global Positioning System (GPS), so much so that it has now become known as the ‘invisible utility’. Seven […]

An inset photograph was taken during the nonlinear emission (SHG and THG) from the NV diamond. Credit: University of Tsukuba
Diamond color centers for nonlinear photonics
Researchers at the University of Tsukuba demonstrated second-order nonlinear optical effects in diamonds by taking advantage of internal color center defects that break inversion symmetry of diamond crystal. Previously, scientists thought that the inversion-symmetric nature […]
