ALBUQUERQUE, NM — While quantum computers could someday revolutionize technology, a single slip of an atom can cause a malfunction. Scientists around the world are figuring out what causes these errors, and it turns out sometimes they stem from the way code in a program is arranged. ALBUQUERQUE, NM — While quantum computers could someday … Read more
The Association for Computing Machinery’s global Technology Policy Council (ACM TPC) has just released “Quantum Computing and Simulation.” It is ACM’s fourth TechBrief: a series of short technical bulletins by ACM TPC that present scientifically grounded perspectives on the impact of specific technological developments in computing and their applications. The Association for Computing Machinery’s global … Read more
Scientists at the Department of Energy’s Oak Ridge National Laboratory used neutron scattering to determine whether a specific material’s atomic structure could host a novel state of matter called a spiral spin liquid. By tracking tiny magnetic moments known as “spins” on the honeycomb lattice of a layered iron trichloride magnet, the team found the … Read more
The art of cryptography is to skillfully transform messages so that they become meaningless to everyone but the intended recipients. Modern cryptographic schemes, such as those underpinning digital commerce, prevent adversaries from illegitimately deciphering messages — say, credit-card information — by requiring them to perform mathematical operations that consume a prohibitively large amount of computational … Read more
In modern cryptosystems, users generate public and private keys that guarantee security based on computational complexity and use them to encrypt and decrypt information. However, recently, modern public-key cryptosystems have faced potential security loopholes against quantum computers with great computational power. As a solution, quantum cryptosystems have been highly noticed. They use quantum keys that … Read more
A research team from the Department of Physics, The University of Hong Kong (HKU), discovered the clear evidence to characterize a highly entangled quantum matter—the quantum spin liquid (QSL) (a phase of matter that remains disordered even at very low temperatures ) from large-scale simulations on supercomputers. This pivotal research work has recently been published … Read more
We all learn from early on that computers work with zeros and ones, also known as binary information. This approach has been so successful that computers now power everything from coffee machines to self-driving cars and it is hard to imagine a life without them. We all learn from early on that computers work with … Read more
Every biological process depends critically on temperature. It’s true of the very small, the very large, and every scale in-between, from molecules to ecosystems and across every environment.

UPTON, NY– After a successful first event, the U.S. Department of Energy’s Office of Science’s National Quantum Information Science (QIS) Research Centers are preparing for their second virtual QIS Career Fair, to be held on Sept. 14, 2022. The event aims to make undergraduate, graduate, and postdoc communities aware of the wide range of QIS … Read more
Particles can move as waves along different paths at the same time – this is one of the most important findings of quantum physics. A particularly impressive example is the neutron interferometer: neutrons are fired at a crystal, the neutron wave is split into two portions, which are then superimposed on each other again. Characteristic … Read more
