An on-chip femtosecond pulse source would unlock new applications in quantum and optical computing, astronomy, optical communications and beyond. However, it’s been a challenge to integrate tunable and highly efficient...
Experiment demonstrates that quantum key distribution networks, which are part of highly secure cryptography schemes, can also detect and locate earthquakes....
Nine technologies developed at MIT Lincoln Laboratory have been selected as R&D 100 Award winners for 2021. Since 1963, this awards program has recognized the 100 most significant technologies transitioned...
Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart....
Quantum cryptography Records with Higher-Dimensional Photons Quantum cryptography is one of the most promising quantum technologies of our time: Exactly the same information is generated at two different locations, and...
Researchers at CU Boulder have designed one of the most precise stopwatches yet—not for timing Olympic sprinters and swimmers but for counting single photons, or the tiny packets of energy...
