Ask a Caltech Expert: Quantum Science and Technology

Ask a Caltech Expert: Rana Adhikari on Quantum Sensors

"We need a huge sensitivity improvement to go from detecting black hole mergers to detecting quieter phenomena, even gravitational waves from the beginning of the universe. As it turns out, the same tools that people use to figure out how to do quantum computing without a lot of errors can be used to make quantum measurements better."

Ask a Caltech Expert: Garnet Chan on Quantum Computers and Chemistry

"The ability to control the quantum state of atoms, molecules, materials, and light is the more fundamental technology, and in some ways, building quantum computers is really an application of it."

Ask a Caltech Expert: Spiros Michalakis and Ed Solomon on Science in Storytelling

"Usually the real-life answers are much cooler than the ones that we make up in our head."

"If you can infuse stories with some cool science—not just facts but some really cool science—and start building a bridge of trust between the academic side and the entertainment industry, I think it can pay off a lot."

Ask a Caltech Expert: John Preskill on Quantum Computers

"Quantum computers will help us to get a better grasp of [new laws of physics] by allowing us to simulate quantum phenomena that would otherwise just be too hard to study."

Ask a Caltech Expert: Nai-Chang Yeh on Quantum Materials

"Frontier technologies are intertwined with quantum science. If we want technology to progress steadily, the development of quantum materials is extremely important."

Ask a Caltech Expert: Nai-Chang Yeh on New Materials and the Future of Quantum Technology

"Quantum materials are not only useful for quantum technology but also for a wide range of applications, such as metrology, sustainability, biomedical and environmental applications, communications, and consumer products."

Ask a Caltech Expert: Kathryn Zurek and Rana Adhikari on Quantum Gravity

"A hundred years ago or so, we had this beautiful unified picture of how all the classical forces worked. And then we had quantum mechanics, which now explains all the forces of nature except gravity. So if you're a physicist, you're always trying to solve the puzzle, how do these things fit together?"
