Entanglement-based Optical Atomic Clock beats the Standard Quantum Limit

Optical lattice clocks (OLC) are widely recognized as the next golden standard for timekeeping. Over the past decades, researchers around the world have made the second the best characterized among all seven of International System of Units (SI units), reaching an unprecedented fractional stability at few parts-of-ten-Quintillion (1019). Despite the tremendous effort of improving technology...

Near Unitary Squeezing

A group at the MIT led by Prof. Vladan Vuletić has recently generated significant amount of spin squeezing-a type of quantum entanglement-in an ultracold vapor of ytterbium-171. Spin squeezed states (SSS) can be used to overcome the standard quantum limit (SQL) which bounds state-of-the-art atomic sensors like optical clocks. The latter deploy a dilute vapor...

Direct Laser Cooling Rubidium Atoms

A group at MIT led by Vladan Vuletic has recently created a Bose-Einstein Condensate (BEC) of rubidium atoms with a new method, direct laser cooling. Many researchers have attempted this elusive goal in the past, but due to various complications resorted to reaching BEC through evaporation instead. Compared to cooling through evaporation, laser cooling is...

Spin Transport in a Mott Insulator of Ultracold Fermions

Superconductivity is a phenomenon in materials whereby electron pairs can flow freely without resistance. As a consequence, no energy is lost while electrical current passes through the superconductor. The benefits, therefore, of superconducting materials which operate at room temperature are countless, and range from revolutionizing the electrical power transmission industry, to providing sweeping improvements in...
