Researchers cut the time for a learning task from 20 million years to 15 minutes
The squeezer—an optical parametric oscillator (OPO) that uses a nonlinear crystal inside an optical cavity to manipulate the quantum fluctuations of light.—is responsible for the entanglement. Credit: Photo: Jonas Schou…
A new twist on Heisenberg’s uncertainty principle can sharpen quantum sensors
Credit: Pixabay/CC0 Public Domain For almost a century, Heisenberg’s uncertainty principle has stood as one of the defining ideas of quantum physics: a particle’s position and momentum cannot be known…
Quantum random number generator combines small size and high speed
A new chip-based quantum random number generator (QRNG) combines miniaturization with high-speed, high-quality operation. The researchers showed it can generate unpredictable random numbers at a rate of 3 Gbps. Credit:…
