The field of attosecond physics was established with the mission of exploring light–matter interactions at unprecedented time resolutions. Recent advancements in this field have allowed physicists to shed new light on the quantum dynamics of […]
Quantum 7, 1195 (2023). https://doi.org/10.22331/q-2023-12-04-1195 The recovery of fragile quantum states from decoherence is the basis of building a quantum memory, with applications ranging from quantum communications to quantum computing. Many recovery techniques, such as […]
Quantum 7, 1194 (2023). https://doi.org/10.22331/q-2023-12-04-1194 A standard approach to quantifying resources is to determine which operations on the resources are freely available, and to deduce the partial order over resources that is induced by the […]
Quantum 7, 1193 (2023). https://doi.org/10.22331/q-2023-12-04-1193 The quasicharge superconducting qubit realizes the dual of the transmon and shows strong robustness to flux and charge fluctuations thanks to a very large inductance closed on a Josephson junction. […]
Insider Brief String theory and loop quantum gravity are the current leading candidates for a quantum theory of gravity. New theory suggests that that spacetime may be classical and not governed by quantum theory at […]
Insider Brief Meta’s leadership doesn’t believe quantum computing will be relevant to their business. The team also sees artificial general intelligence — AGI — as a distant threat/opportunity. Chief scientist Yann LeCun discussed his opinion […]
Insider Brief Algorithmiq reports it successfully ran a large-scale error mitigation experiments to date on IBM’s hardware. Algorithmiq’s proprietary error mitigation algorithms were run on the IBM Nazca, the 127 qubit Eagle processor. The team […]
Differentiable matrix product states for simulating variational quantum computational chemistry0 (0)
Quantum 7, 1192 (2023). https://doi.org/10.22331/q-2023-12-04-1192 Quantum Computing is believed to be the ultimate solution for quantum chemistry problems. Before the advent of large-scale, fully fault-tolerant quantum computers, the variational quantum eigensolver (VQE) is a promising […]
At its annual Quantum Summit in New York, IBM unveiled its quantum roadmap for both hardware and software through the next 10 years. It represents a continuation of the roadmaps they have presented but also […]
In April 2021, the U.S. Defense Advanced Research Projects Agency (DARPA) announced a Quantum Benchmarking program to estimate the long-term utility of quantum computers by creating new benchmarks that can quantify progress towards specific computational […]
