Can an algorithm teach scientists to write better quantum computer

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

ACM TechBrief warns of promise and peril of “sleeper” quantum

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

Magnetic quantum material broadens platform for probing next-gen

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

A key role for quantum entanglement

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

KIST develops key technology for quantum cryptography commercialization

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

HKU physicists found signatures of highly entangled quantum matter

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

New model predicts how temperature affects life from quantum to classical scales

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. 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 … Read more

National Quantum Information Science Research Centers to host virtual career fair Sept. 14

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

A quantum wave in two crystals – BIOENGINEER.ORG

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
