Graphene Valleytronics: Paving the Way to Small-Sized Room-Temperature Quantum Computers

Valleytronics is an emerging field in which valleys—local minima in the energy band structure of solids—are used to encode, process, and store quantum information. Though graphene was thought to be unsuitable for valleytronics due to its symmetrical structure, researchers from the Indian Institute of Technology Bombay, India, have recently shown that this is not the case. Their findings may pave the way to small-sized quantum computers that can operate at room temperature.

Getting the Output Right: Team Takes to Task Achieving Full Advantage of Quantum Computing

Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world’s largest supercomputers. Yet, these devices are extremely sensitive to external influences and thus prone to errors which can change the result of the computation. This is particularly challenging for quantum computations that are beyond the reach of our trusted classical computers, where we can no longer independently verify the results through simulation. “In order to take full advantage of future quantum computers for critical calculations we need a way to ensure the output is correct, even if we cannot perform the calculation in question by other means,” says Chiara Greganti from the University of Vienna.

IonQ Opens Door to Dramatically More Powerful Quantum Computers, Debuts Industry First: Reconfigurable Multicore Quantum Architecture

IonQ, Inc. (“IonQ”), the leader in quantum computing, August 25, 2021, unveiled the industry’s first Reconfigurable Multicore Quantum Architecture (RMQA) technology, a breakthrough in quantum computing. Starting with the demonstration of 4 chains of 16 ions each that can be dynamically configured into quantum computing cores, IonQ believes it has laid the foundation for increases to qubit count into the triple digits on a single chip, as well as future Parallel Multicore Quantum Processing Units.

Quantum Error Correction, Quantum Volume Records, and Quantum Optimization all Part of Honeywell’s & CQC’s Recent Breakthroughs

For the first time, researchers at Honeywell Quantum Solutions demonstrated repeated rounds of real-time quantum error correction (QEC), an advancement that represents a significant step toward the realization of large-scale quantum computing. The company also achieved a quantum volume of 1,024, doubling its own record from just four months ago. Beyond the hardware milestones, Cambridge Quantum also has developed a new quantum algorithm that uses fewer qubits to solve optimization problems.
