Quantum Science and Atomic Clocks
Abstract: Quantum state engineering, many-body physics, and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to explore emerging quantum phenomena and probe fundamental physics. Recent advances include precise control of atomic interactions to achieve high accuracy, determination of gravitational time dilation across a few hundred micrometers, and employment of spin entanglement for clock comparison.

About the Columbia Quantum Initiative:
In the first half of the 20th century, the first quantum revolution gave us a new way of thinking about the way the world works and brought us technologies such as lasers, MRI machines, and the transistors that underpin all aspects of modern life. Today, the second quantum revolution is underway, and it’s all about control.
The coming generation of quantum technologies will be built on new physical principles and demand new materials, new methods of investigation, and new collaborations. At Columbia, we’re tackling these demands together and training the next generation of quantum scientists and entrepreneurs.
Building on the collaborative culture long fostered at Columbia, the Quantum Initiative is combining interdisciplinary expertise in materials science, photonics, quantum theory, and more, all while taking advantage of our unique position in the global hub that is New York to develop novel quantum technologies that will open new frontiers into how we compute through complex problems, communicate with one another, and sense the world around us.
