Researchers introduce a new class of twistable materials, unlocking unprecedented quantum possibilities. Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today’s “alchemy” by creating entirely new phases of matter through simple geometric manipulation. The term “moiré” may sound familiar—it describes the st
PRESS RELEASE — Quantum computers have operated under a significant limitation: they can run only one program at a time. These million-dollar machines demand exclusive use even for the smallest tasks, leaving much of their expensive and fast-running hardware idle and forcing researchers to endure long queues.
Columbia Engineering researchers have developed HyperQ, a novel system that enables multiple users to share a single quantum computer simultaneously through isolated quantum virtual machines (qVMs). This key development brings quantum computing closer to real-world usability—more practical, efficient, and broadly accessible.
“HyperQ brings cloud-style virtualization to quantum computing,” said Jason Nieh, professor of computer science at Columbia Engineering and co-director of the Software Systems Laboratory. “It lets a single machine run multiple programs at once—no interference, no waiting in line.”
In physics, there are two great pillars of thought that don’t quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, and the weak nuclear force. Meanwhile, Einstein’s general relativity describes gravity and the fabric of spacetime.
However, these frameworks are fundamentally incompatible in many ways, says Jonathan Heckman, a theoretical physicist at the University of Pennsylvania. The Standard Model treats forces as dynamic fields of particles, while general relativity treats gravity as the smooth geometry of spacetime, so gravity “doesn’t fit into physics’s Standard Model,” he explains.
In a recent paper in Physical Review Research, Heckman, Rebecca Hicks, a Ph.D. student at Penn’s School of Arts & Sciences, and their collaborators turn that critique on its head. Instead of asking what string theory predicts, the authors ask what it definitively cannot create. Their answer points to a single exotic particle that could show up at the Large Hadron Collider (LHC). If that particle appears, the entire string-theory edifice would be, in Heckman’s words, “in enormous trouble.”
