Novel atomic clock design offers ‘tweezer’ control

Researchers at JILA, a joint research institute operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, have demonstrated a novel atomic clock design that combines near-continuous operation with […]

Physicists finally nail the proton’s size

In 2010, Randolf Pohl of the Max Planck Institute of Quantum Optics (Quantamagazine) announced his team precisely measured the size of the proton by substituting the electron of a hydrogen atom by a muon. The size […]

NASA has developed a new quantum gravity sensor

The quantum sensor, which NASA has developed with Bay Area-based company AOSense, relies on some 100 million cesium atoms. The device launches the atoms inside a cylindrical column and times how quickly they fall. Atoms […]

What is Quantum probability?

Different approaches to quantum mechanics invoke different meanings of probability. What is “probability”? This very amazing article discusses three of the leading approaches to quantum theory: the “dynamical collapse” theories, such as the GRW model, the […]

NIST: Second round in post-quantum cryptography

NIST (US National Institute of Standards and Technology) has enlisted researchers from academia and private industry to get quantum-resistant cryptography ready for 2022. The agency is overseeing the second phase of its Post-Quantum Cryptography Standardization Process to narrow down the […]

Researchers propose a quantum network protocol stack

Delft University researchers presented an interesting paper (A Link Layer Protocol for Quantum Networks) at the recent ACM SIGCOMM conference regarding the challenges of building a quantum communication network stack. Effective quantum networking needs a robust networking […]
