Fraud-proof credit cards possible with quantum physics
Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Researchers find qubits based on trapped ions offer a promising scalable platform for quantum computing
Cooling with the coldest matter in the world
Physicists at the University of Basel have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree ...
Simon's algorithm run on quantum computer for the first time—faster than on standard computer
Revving up fluorescence for superfast LEDs: Researchers set speed record for molecular fluorescence
Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal—setting a speed record and making an important step toward realizing superfast light emitting ...
Putting the squeeze on quantum information
Canadian Institute for Advanced Research researchers have shown that information stored in quantum bits can be exponentially compressed without losing information. The achievement is an important proof of principle, and could ...
Fluid mechanics suggests alternative to quantum orthodoxy
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum ...
'Solid' light could compute previously unsolvable problems
Researchers at Princeton University have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter.
