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 ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems.

A research team affiliated with UNIST has unveiled a quantum device, capable of ultra-fast operation, a key step toward ...

Long-range couplings between lattice sites algorithmically speed up the efficiency of quantum walks. Scientists in China ...

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 ...

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 ...
