One year after initial deliveries of solid-state battery prototypes to its automotive partners, QuantumScape is receiving additional praise from PowerCo – the battery-centric subsidiary of Volkswagen Group – for the potential of its technology. PowerCo recently completed an endurance test with QuantumScape’s solid-state cells and determined they can someday power EVs that can drive 500,000 kilometers with virtually no loss of range.

QuantumScape ($QS) is an advanced battery technology company that has been working for over a decade to develop scalable, energy-dense solid-state battery cells that can one-day power EVs that are safer, charge faster, and drive farther.

During QuantumScape’s tenure in solid-state battery development, Volkswagen Group has been a partner from early on and remains one of the startup’s largest investors. OEMs like Volkswagen have helped empower QuantumScape to continue its development and deliver some of the most promising solid-state battery technology in the industry.

Ultra-intense ultrashort lasers have a wide-ranging scope of applications, encompassing basic physics, national security, industrial service, and health care. In basic physics, such lasers have become a powerful tool for researching strong-field laser physics, especially for laser-driven radiation sources, laser particle acceleration, vacuum quantum electrodynamics, and more.

A dramatic increase in peak laser power, from the 1996 1-petawatt “Nova” to the 2017 10-petawatt “Shanghai Super-intense Ultrafast Laser Facility” (SULF) and the 2019 10-petawatt “Extreme Light Infrastructure—Nuclear Physics” (ELI-NP), is due to a shift in gain medium for large-aperture lasers (from neodymium-doped glass to titanium:sapphire crystal). That shift reduced the pulse duration of high-energy lasers from around 500 femtoseconds (fs) to around 25 fs.

However, the upper limit for titanium: sapphire ultra-intense ultrashort lasers appears to be 10-petawatt. Presently, for 10-petawatt to 100-petawatt development planning, researchers generally abandon the titanium: sapphire chirped pulse amplification technology, and turn to optical parametric chirped pulse amplification technology, based on deuterated potassium dihydrogen phosphate nonlinear crystals. That technology, due to its low pump-to-signal conversion efficiency and poor spatiotemporal-spectral-energy stability, will pose a great challenge for the realization and application of the future 10–100 petawatt lasers.

Small and medium-sized enterprises should be ready for opportunities and threats of the oncoming quantum era.

In this introduction to quantum consciousness, Justin Riddle presents six arguments that quantum consciousness is an important theory of mind.\

To summarize them briefly, People always identify as their latest technology and so most people believe that they are a digital computer. Time to update those models of self, because… Quantum computers are here. We wouldn’t want the brick of metal in our pocket to have greater computational power than our brain. People say the brain is too warm, wet, and noisy for quantum effects; yet, evidence keeps emerging for quantum effects in biology (such as photosynthesis). Where do we draw the line? Evolution might be selecting for quantum systems that can maintain quantum coherence. The debate around the role of quantum mechanics in consciousness has been raging for 100 years. Many key historical figures like Bohr, Schrodinger, Heisenberg, von Neumann entertained the idea that quantum mechanics might relate to our mind. Physical theories that are purely deterministic have failed to account for key aspects of subjective experience. There may be novel answers from a perspective that incorporate new physics.\

Entanglement is a property of quantum physics that is manifested when two or more systems interact in such a way that their quantum states cannot be described independently. In the terminology of quantum physics, they are said to be entangled, i.e. strongly correlated. Entanglement is of paramount importance to quantum computing. The greater the entanglement, the more optimized and efficient the quantum computer.

A study conducted by researchers affiliated with the Department of Physics at São Paulo State University’s Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, tested a novel method of quantifying entanglement and the conditions for its maximization. Applications include optimizing the construction of a quantum computer.

An article on the study is published as a letter in Physical Review B.

For a while researchers thought they’d have to make do with noisy, error-prone systems, at least in the near term. That’s starting to change.

EV batteries tend to lose range capacity over their lifetime, but Volkswagen-backed startup PowerCo says it tested one from California-based QuantumScape that ‘practically does not age.’
