Quantum frequency transducer (QFT) is a lead edge technology born from nonlinear optics, which is a basic tool in quantum information technology. QFT is a technology that the wavelength of a photonic ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

Key result A six-year-long research effort has seen researchers in Canada build a chip-scale device that can generate multiphoton entangled states. (Courtesy: Ultrafast Optical Processing Group) ...

IONQ ramps up M&A with Seed Innovations and a $1.8B SkyWater deal to build a vertically integrated, enterprise-grade quantum platform.

A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...

Despite these challenges, frequency-bin pairs -- two qudits in the form of photons that are entangled in their frequencies -- are well suited to carrying quantum information because they can follow a ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

Scientists at TU Delft have designed a nanostring resonator that, when driven at its lowest vibration frequency, quietly funnels energy through a chain of higher modes all the way up to the fifth, ...

An international team of researchers has forced light to replicate the quantum Hall effect, a Nobel Prize–winning phenomenon ...

QUBT rides on booming TFLN demand with $1.5B raised and strong customer traction - but is its 600x sales valuation too rich to ignore?
