An IQIM collaboration between the Endres group and Alicea group, working with theorists at Université Paris-Saclay and the Technical University of Munich, performed first-of-their-kind experiments on two different conformal field theories using quantum simulators. Using new technology developed for these quantum simulators, the team reports the first direct measurement of energy levels in synthetic quantum [...]
Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing the errors that riddle today's rudimentary quantum computers. Whereas these machines were previously thought to require millions of qubits to work [...]
Welcome to the Quantum Revolution (TQR)! John Preskill is featured in conversation with Antonella Navarro, host of the newly launched TQR podcast. Learn more about John Preskill’s path from particle physics to quantum information. Recorded during the 2025 Quantum2Business conference, they discuss a shift from Noisy Intermediate Scale Quantum (NISQ) to Fault Tolerant Error Correction [...]
Atomically resolved image of twisted-trilayer graphene obtained by scanning tunneling microscope.Scale bar 10nm. Credit: Nadj-Perge Lab. Magic-angle graphene hosts robust unconventional superconductivity, yet its underlying mechanism has remained elusive despite years of investigation. A new study from IQIM researchers establishes that magic-angle twisted trilayer graphene becomes superconducting only after passing through a sequence [...]
In September 2000, Caltech's Institute for Quantum Information and Matter (IQIM) was born (albeit with a different name, the Institute for Quantum Information, or IQI). At the time, it was one of the world's first centers dedicated to the study of quantum information science—a field that uses the laws of quantum physics to create better [...]
An international, multi-institution effort has shown a significant speed-up in using quantum learning techniques to characterize physical systems. The researchers showed that while a classical, entanglement-free approach to these measurements would take 20 million years, their quantum, entanglement-enhanced approach took less than 15 minutes. Quantum learning advantage on a scalable photonic platform, appearing in Science, [...]

Superconducting qubits possess outstanding capabilities for processing quantum information in the microwave domain; however they have limited coherence times. An interface between photons and phonons could allow quantum information to be stored in long-lived mechanical oscillators. Here, we introduce a platform that relies on electrostatic forces in nanoscale structures to achieve strong coupling between a [...]
BASILISK, the global esports organization built to champion science, debuted two historic partnerships at the Esports World Cup 2025 in Riyadh, Saudi Arabia this week – furthering its mission to elevate science advocacy through the global reach and cultural influence of competitive gaming. BASILISK's new strategic partnerships with the California Institute of Technology's Institute for Quantum [...]
As part of the International Year of Quantum celebrations, Physics Today features notable entries including this June 1999 article by John Preskill Battling Decoherence: The Fault-Tolerant Quantum Computer Quantum computers have the potential to do certain calculations faster than any foreseeable classical computers, but their success will depend on preserving complex coherent quantum states. Recent [...]
