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 […]
A research team has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study […]
A research team has achieved the loophole-free test of Hardy’s paradox for the first time. The team successfully demonstrated Hardy’s nonlocality while closing both the detection efficiency loophole and the locality loophole. Click to rate […]
Insider Brief Researchers at the University of Minnesota Twin Cities provided fundamental insights into planar hyperbolic polaritons—quasiparticles formed from light-matter interactions in 2D materials—that could enable highly directional energy transport, amplifying light-matter interactions at the […]
Quantum 8, 1448 (2024). https://doi.org/10.22331/q-2024-08-27-1448 We propose a new model of quantum computation comprised of low-weight measurement sequences that simultaneously encode logical information, enable error correction, and apply logical gates. These measurement sequences constitute a […]
