New Energy Superposition Battery

Are quantum batteries based on quantum superpositions of trajectories?

We propose charging protocols for quantum batteries based on quantum superpositions of trajectories. Specifically, we consider that a qubit (the battery) interacts with multiple cavities or a single cavity at various positions, where the cavities act as chargers.

Can superabsorption make quantum batteries a reality?

Researchers at the University of Adelaide and their overseas partners have taken a key step in making quantum batteries a reality. They have successfully proved the concept of superabsorption, a crucial idea underpinning quantum batteries.

Could a quantum battery revolutionize energy storage?

The so-called quantum battery offers the potential to be far more compact, efficient, and faster charging than conventional batteries. The team’s findings, recently published in Physical Review Letters, showcase a design based on quantum spin systems that could revolutionize how we store and use energy.

Why do quantum batteries charge so fast?

Underlying the superabsorbing effect of the quantum batteries is the idea that all the molecules act collectively through a property known as quantum superposition,” said Dr Quach. “It is theoretically possible that the charging power of quantum batteries increases faster than the size of the battery which could allow new ways to speed charging.”

What is superposition in quantum computing?

Zhu and colleagues' approach follows on from a quantum phenomenon known as superposition, which is commonly recalled for quantum computing, and is where particles exist in a flurry of possible states until the moment they're measured. This overlay of possibilities also messes with the natural order of time, researchers have recently shown.

Could a quantum battery never lose its charge?

In 2019, a team of Canadian-based researchers laid out a blueprint for a quantum battery that never loses its charge. Their idea, which is still totally theoretical, hinges on a different quantum mechanism: one that involves luring quantum components into a 'dark state' where the material can't interact with, or lose energy to, its environment.
