Insider Brief Diraq reached a key milestone by unlocking the potential of quantum computers to operate at warmer temperatures. Engineers showed the company’s spin-based quantum processors to operate at temperatures 20 times warmer than previously […]
Quantum 8, 1304 (2024). https://doi.org/10.22331/q-2024-03-28-1304 Multipartite entangled states are an essential resource for sensing, quantum error correction, and cryptography. Color centers in solids are one of the leading platforms for quantum networking due to the […]
Future quantum computers could be based on electrons floating above liquid helium, according to study by a RIKEN physicist and collaborators, appearing in Physical Review Applied. Click to rate this post! [Total: 0 Average: 0]You […]
Rice University engineers have demonstrated a way to control the optical properties of atomic imperfections in silicon material known as T centers, paving the way toward leveraging these point defects for building quantum nodes for […]
A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) […]
The renowned Polish piano duo Marek and Wacek didn’t use sheet music when playing live concerts. And yet onstage the pair appeared perfectly in sync. On adjacent pianos, they playfully picked up various musical themes, […]
Birds flock. Locusts swarm. Fish school. Within assemblies of organisms that seem as though they could get chaotic, order somehow emerges. The collective behaviors of animals differ in their details from one species to another, […]
Quantum 8, 1303 (2024). https://doi.org/10.22331/q-2024-03-28-1303 We show that it is possible to perform Heisenberg-limited metrology on GHZ-like states, in the presence of generic spatially local, possibly strong interactions during the measurement process. An explicit protocol, […]
Quantum 8, 1302 (2024). https://doi.org/10.22331/q-2024-03-28-1302 We develop an architecture for measurement-based quantum computing using photonic quantum emitters. The architecture exploits spin-photon entanglement as resource states and standard Bell measurements of photons for fusing them into […]
Quantum 8, 1301 (2024). https://doi.org/10.22331/q-2024-03-28-1301 Boundaries of Walker-Wang models have been used to construct commuting projector models which realize chiral unitary modular tensor categories (UMTCs) as boundary excitations. Given a UMTC $mathcal{A}$ representing the Witt […]
