A photonic quantum computing company wants to light the way – figuratively and literally – to an era when as many users as possible can rely on quantum computers to solve computational challenges that classical […]
Insider Brief The USTC team successfully conducted the first loophole-free test of Hardy’s paradox, marking a significant step in quantum physics by conclusively demonstrating quantum nonlocality. The experiment showed a violation of local realism with […]
Insider Brief Researchers have developed a unified mathematical theory to explain and predict barren plateaus in quantum algorithms, a major challenge in quantum computing. The study provides a set of guidelines to help scientists avoid […]
UCLA’s California NanoSystems Institute, in collaboration with the University of Delaware, Caltech, and MIT, has secured a $1 million grant from the National Science Foundation (NSF) to advance quantum technologies. The funding supports the Quantum […]
Part 3: The primary algorithms VQA, VQE and QAOA QAOA Example Problem. Credit: Google Quantum AI Variational Quantum Algorithms (VQA) In the NISQ era, variational circuits serve as a bridge between the classical and the […]
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and high-precision measurements. This light source is […]
Quantum 8, 1450 (2024). https://doi.org/10.22331/q-2024-08-27-1450 We propose a decoder for the correction of erasures with hypergraph product codes, which form one of the most popular families of quantum LDPC codes. Our numerical simulations show that […]
Bruno Uchoa, a professor of condensed matter physics, and Hong-yi Xie, a postdoctoral fellow in condensed matter physics at the University of Oklahoma, have published research in the journal Proceedings of the National Academy of […]
The Quantum Insider partners with MATTER to create a milestone initiative and marquee forum, XPANSE Quantum, November 20-22, to cultivate strategic relationships with 2,500 key decision-makers in the UAE. An exclusive event that activates the […]
Quantum 8, 1449 (2024). https://doi.org/10.22331/q-2024-08-27-1449 We consider the task of simulating time evolution under a Hamiltonian $H$ within its low-energy subspace. Assuming access to a block-encoding of $H’:=(H-E)/lambda$, for some $lambda gt 0$ and $E […]
