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 […]
Quantum 8, 1447 (2024). https://doi.org/10.22331/q-2024-08-27-1447 The multitime probability distributions obtained by repeatedly probing a quantum system via the measurement of an observable generally violate Kolmogorov’s consistency property. Therefore, one cannot interpret such distributions as the […]
Quantum 8, 1446 (2024). https://doi.org/10.22331/q-2024-08-27-1446 The survival probability of an initial Coherent Gibbs State (CGS) is a natural extension of the Spectral Form Factor (SFF) to open quantum systems. To quantify the interplay between quantum […]
Quantum 8, 1445 (2024). https://doi.org/10.22331/q-2024-08-27-1445 The rates of several device-independent (DI) protocols, including quantum key-distribution (QKD) and randomness expansion (RE), can be computed via an optimization of the conditional von Neumann entropy over a particular […]
A team led by Stevens professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity—and making that experiment real should be possible with quantum technology, […]
Researchers from the University of Edinburgh used NVIDIA’s CUDA-Q platform to simulate quantum clustering algorithms, significantly reducing the qubit count needed for large datasets. The team developed a method using coresets, allowing quantum machine learning […]
