Cooling Teleportation…

Topics: CERN, Condensed Matter Physics, Entanglement, Lasers, Quantum Mechanics Much of modern experimental physics relies on a counterintuitive principle: Under the right circumstances, zapping matter with a laser doesn’t inject energy into the system; rather, it sucks energy out. By cooling the system to a fraction of a degree above absolute zero, one can observeContinue reading “Cooling Teleportation…”

Flirting by Starlight…

Topics: Astrophysics, Electromagnetic Radiation, Entanglement, SETI When we gaze up at the night sky, we might be accidentally eavesdropping on an alien conversation. At least, that’s according to Imperial College London quantum physicist Terry Rudolph, who last week published preprint research theorizing that an advanced extraterrestrial civilization might alter the light coming off stars in order toContinue reading “Flirting by Starlight…”

Untangling Entanglement…

Topics: Entanglement, Quantum Mechanics, Quantum Optics Natalia Herrera-Valencia and colleagues have successfully unscrambled entangled light after it has passed through a 2 m long multimode fibre. Led by Mehul Malik, the team at the Heriot-Watt University in Edinburgh tackled the challenge using entanglement itself. The research was done in collaboration with a colleague at theContinue reading “Untangling Entanglement…”
