In a study published in Nature, a research team has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM). Click to rate this post! […]
Quantum 8, 1405 (2024). https://doi.org/10.22331/q-2024-07-10-1405 We propose an estimation procedure for $d$-dimensional unitary transformations. For $dgt2$, the unitary transformations close to the identity are estimated saturating the quantum Cramér-Rao bound. For $d=2$, the estimation of […]
Quantum 8, 1404 (2024). https://doi.org/10.22331/q-2024-07-10-1404 The classical embeddability problem asks whether a given stochastic matrix $T$, describing transition probabilities of a $d$-level system, can arise from the underlying homogeneous continuous-time Markov process. Here, we investigate […]
In the fall of 2014, Andrew Wilson took a front-row seat in Ken Ono’s number theory class at Emory University in Atlanta. Wilson was not only double majoring in applied math and physics, he was […]
A team of experimental physicists led by the University of Cologne have shown that it is possible to create superconducting effects in special materials known for their unique edge-only electrical properties. This discovery provides a […]
In a recent interview at Pasqal Thoughts 2024, Stéphane Requena, CTO at GENCI (Grand Équipement National de Calcul Intensif), discussed the pioneering collaboration between Pasqal’s Quantum Processing Units (QPU) and the CEA’s High-Performance Computing (HPC) […]
Insider Brief French companies have joined forces in an innovative project to optimize energy consumption in quantum computing. The project seeks to compare the energy requirements of solving relevant industry use cases on classical high-performance […]
Insider Brief Quantum can help develop cutting-edge technologies, enhance national security and progress towards its NATO defense spending targets, according to an opinion piece in The Hill. Quantum experts suggest the dual-use of quantum tech […]
Quantum 8, 1403 (2024). https://doi.org/10.22331/q-2024-07-10-1403 The CSS code construction is a powerful framework used to express features of a quantum code in terms of a pair of underlying classical codes. Its subsystem extension allows for […]
Quantum 8, 1402 (2024). https://doi.org/10.22331/q-2024-07-10-1402 Communication complexity quantifies how difficult it is for two distant computers to evaluate a function $f(X,Y)$, where the strings $X$ and $Y$ are distributed to the first and second computer […]
