We invite you to the next QWebinar. This time we will have a talk “Understanding quantum matter using intelligent machines” by Eliška Greplová from Delft University of Technology. Date: Wed, Feb 10, 2021, 18:00 (GMT+1) […]
Quantum 5, 393 (2021). https://doi.org/10.22331/q-2021-02-04-393 Gauge theories establish the standard model of particle physics, and lattice gauge theory (LGT) calculations employing Markov Chain Monte Carlo (MCMC) methods have been pivotal in our understanding of fundamental […]
Quantum 5, 392 (2021). https://doi.org/10.22331/q-2021-02-04-392 Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far that exploits both the […]
Quantum 5, 391 (2021). https://doi.org/10.22331/q-2021-01-28-391 We propose an efficient method for simultaneously optimizing both the structure and parameter values of quantum circuits with only a small computational overhead. Shallow circuits that use structure optimization perform […]
Quantum 5, 390 (2021). https://doi.org/10.22331/q-2021-01-28-390 We discuss the notion of coherent states from three different perspectives: the seminal approach of Schrödinger, the experimental take of quantum optics, and the theoretical developments in quantum gravity. This […]
Quantum 5, 389 (2021). https://doi.org/10.22331/q-2021-01-28-389 Quantum nonlocal correlations are generated by implementation of local quantum measurements on spatially separated quantum subsystems. Depending on the underlying mathematical model, various notions of sets of quantum correlations can […]
Quantum 5, 388 (2021). https://doi.org/10.22331/q-2021-01-28-388 As the hardware technology for quantum computing advances, its possible applications are actively searched and developed. However, such applications still suffer from the noise on quantum devices, in particular when […]
Quantum 5, 387 (2021). https://doi.org/10.22331/q-2021-01-26-387 We introduce a new quantum Rényi divergence $D^{#}_{alpha}$ for $alpha in (1,infty)$ defined in terms of a convex optimization program. This divergence has several desirable computational and operational properties such […]
Quantum 5, 386 (2021). https://doi.org/10.22331/q-2021-01-25-386 Hybrid quantum-classical optimization algorithms represent one of the most promising application for near-term quantum computers. In these algorithms the goal is to optimize an observable quantity with respect to some […]
Scott Aaronson originated the proposal of Boson Sampling as an area where quantum computers should be better than regular computers. He discusses the new claim from China of Quantum Supremacy where quantum computing systems are […]
