Atomic clocks are the most precise timekeepers we have today, with the best ones keeping time to within one second in 15 billion years. But there’s always room for improvement, as researchers at MIT have now demonstrated with a new quantum-entangled at… Continue reading Quantum-entangled atomic clock keeps spookily accurate time
Engineers at Brookhaven National Laboratory have designed a strange new X-ray microscope that takes advantage of the spooky world of quantum physics to “ghost image” biomolecules in high resolution but at a lower radiation dose.Continue ReadingCategory… Continue reading Quantum X-ray microscope “ghost images” molecules using entanglement
Researchers have managed to demonstrate quantum entanglement on a small satellite orbiting Earth. The team developed a miniaturized device that can produce pairs of photons that are inextricably linked, which could help launch a fast and secure quantum… Continue reading Quantum entanglement demonstrated on tiny CubeSat in orbit
Quantum entanglement is a phenomenon that’s as bizarre as it is fragile. Entangled particles are thought to lose this inexplicable link when exposed to outside factors. But now, physicists have managed to produce hot clouds of trillions of entangled at… Continue reading 15 trillion quantum entangled atoms make a record-breaking hot mess
The weird world of quantum physics is being harnessed for some fascinating use cases. In the latest example, physicists have developed and demonstrated a “quantum radar” prototype that uses the quantum entanglement phenomenon to detect objects, a syste… Continue reading “Quantum radar” uses entangled photons to detect objects
Radar was a great invention that made air travel much safer and weather prediction more accurate, indeed it is even credited with winning the Battle of Britain. However, it carries a little problem with it during times of war. Painting a target with radar (or even sonar) is equivalent to …read more
Canada is investing $2.7 million to develop quantum radar technology. Continue reading A ‘Quantum Radar’ System Will Watch for Stealth Aircraft and Missiles in the Arctic
The Joint Quantum Institute published a recent paper detailing a quantum computer constructed with five qubits formed from trapped ions. The novel architecture allows the computer to accept programs for multiple algorithms.
Quantum computers make use of qubits and trapped ions–ions confined with an electromagnetic field–are one way to create them. In particular, a linear radio frequency trap and laser cooling traps five ytterbium ions with a separation of about 5 microns. To entangle the qubits, the device uses 50 to 100 laser pulses on individual or pairs of ions. The pulse shape determines the actual function performed, which is …read more
