Bright background light can do more than clutter a quantum experiment. It can wash out the very features that make quantum ...

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, ...

Researchers at the Technion—Israel Institute of Technology have, for the first time, measured the temporal duration of ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

Researchers developed a quantum-dot circularly polarized light sensor using chiral charge transport layers, spanning ultraviolet to short-wave infrared wavelengths.

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum ...

Photon blockade is a quintessential phenomenon in quantum optics, wherein a strongly nonlinear system prevents the absorption of additional photons once a single photon is present, effectively ...

To overcome this noise limitation, the team drew inspiration from a quantum effect known as “energy-time entanglement”. Instead of generating quantum light, they recreated its key noise-resistant ...

Quantum optics, the study of the interaction between light and matter at the quantum level, has increasingly focused on the rich dynamics that emerge from atomic ensembles. In these systems, groups of ...

In a recent gift to the Quantum Scholars program, local optics company Meadowlark Optics is generously supporting $70,000 in scholarships for undergraduates exploring the quantum field at the ...
