Reporting in the February 26 issue of the journal Nature, a team of scientists from AWS and Caltech demonstrate a new quantum chip architecture for suppressing errors using a type of qubit known as a cat qubit. Cat qubits were first proposed in 2001, and, since then, researchers have developed and refined them. Now, the [...]
Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple quantum bits, or qubits—the fundamental information-storing building blocks of quantum computers. The work is described in a paper published on February 26 in the journal Nature, Multiplexed [...]
Harry Jeffrey Kimble, the William L. Valentine Professor of Physics, Emeritus, passed away on September 2, 2024, at the age of 75. A giant in the field of physics, Kimble—who was also known as H.J. Kimble and Jeff Kimble—performed groundbreaking experiments in quantum optics and quantum information science. His achievements include some of the earliest [...]
John Preskill is featured in the current issue of the Experimental Physics newletter for CERN. Read the full article here. In this exclusive interview, we sit down with John Preskill, a pioneering physicist and leading expert in quantum computing. As a professor at Caltech and the director of the Institute for Quantum Information and Matter, [...]
Quantum computers of the future may ultimately outperform their classical counterparts to solve intractable problems in computer science, medicine, business, chemistry, physics, and other fields. But the machines are not there yet: They are riddled with inherent errors, which researchers are actively working to reduce. One way to study these errors is to use classical [...]
Quantum teleportation isn’t just science fiction; it’s entirely real and happening in laboratories today. But teleporting quantum particles and information is a far cry from beaming people through space. In some ways, it’s even more astonishing. John Preskill, a theoretical physicist at the California Institute of Technology, is one of the leading theoreticians of quantum computing [...]
Quanta magazine features recent work by John Preskill, Hsin-Yuan (Robert) Huang, IQIM graduate student Chi-Fang (Anthony) Chen, and DuBridge Postdoctoral Scholar Leo Zhou toward identifying a viable problem that confers a quantum advantage — something only a quantum computer can solve. Only then, scientists argue, will the technology be seen as essential. By studying the [...]
The Eighth Biennial John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and Their Applications is awarded to John Preskill (Richard P. Feynman Professor of Theoretical Physics, California Institute of Technology) for developments at the interface of efficient learning and processing of quantum information in quantum computation, and following upon long standing [...]
In Science Journeys, Caltech graduate students and postdoctoral scholars discuss a range of scientific topics that will spark students' curiosity and provide educators with supplemental resources to continue that exploration in the classroom. Arian Jadbabaie PhD 23 featured in Caltech program Science Journeys IQIM student Arian Jadbabaie did his PhD work in the [...]
Caltech and Broadcom announced a multi-year partnership to advance quantum science research and discoveries with the potential to seed new innovative technologies and applications. The partnership, supported with a significant investment from Broadcom, will establish the Broadcom Quantum Laboratory at Caltech, a physical collaboration space that will bring together experts in the fields of quantum [...]
