System infrastructure
The set-up of the Light Wave Synthesizer 100 (LWS100) is shown in Fig. 1. It starts with the first part of the front end, a Pharos pump laser (Light Conversion), including a 75-MHz mode-locked Yb:KGW (potassium gadolinium…

Scientists just recreated a 1938 experiment that could rewrite fusion history
A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium (DT) fusion observation. As described in Physical Review C, the reworking of the previously unheralded experiment…

The Quantum Battery That Flipped Entanglement: A Stunning Reversal of the Rules
Scientists have discovered a way to make quantum entanglement reversible, something long thought to be impossible, by using a conceptual device called an entanglement battery. Much like a regular battery stores energy, this theoretical tool can…

Dispersion-tunable low-loss implanted spin-wave waveguides for large magnonic networks
Spin waves are collective excitations of magnetization in magnetic materials, which present enticing prospects for next-generation information processing1,2,3. Their distinctive attributes, such as high-speed operation within the gigahertz to…

Single nuclear spin detection and control in a van der Waals material
Sample preparation
The hBN thin flakes were tape-exfoliated from a monocrystalline hBN crystal and transferred onto Si/SiO2 substrates. Then we irradiated the hBN flakes with 2.5 keV 13CO2 (99.0% 13C, Sigma-Aldrich) ions with a dose density of…

Holographic deep thermalization for secure and efficient quantum random state generation
Preliminary
Statistical properties of a quantum state ensemble \({{{\mathcal{E}}}}(\Psi )=\{\left\vert {\psi }_{z}\right\rangle,{p}_{z}\}\) are characterized by its Kth moment (K ≥ 1), which is captured by the Kth moment operator of the…

Creation and characterization of warm dense matter isochorically heated by an intense laser-driven proton beam to temperatures exceeding 100 eV
Experimental setup
The experiment was conducted at the OMEGA-EP laser facility, where the EP short-pulse beam was focused onto solid plastic targets to generate a proton beam via TNSA. Two types of proton source targets were used in this…
