A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Army ...
Harvard John A. Paulson School of Engineering and Applied Sciences Nature has a way of finding optimal solutions to complex problems. For example, despite the billions of ways for a single protein to ...
Menlo's optical frequency combs are a core component of optical clocks, such as this one at JILA. (Courtesy: GE Marti/JILA) This year marks the 20th anniversary of the first time an optical-frequency ...
Physicists in the US have created an optical frequency comb that operates in the extreme ultraviolet (XUV). Touted as the first practical comb to work in this region of the spectrum, the device could ...
The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency ...
This framework enables quantitative predictions about how cellular systems convert frequency-encoded signals into precise ...
