When we checked Amazon, the AA Quantums have 25% one-star reviews while not quite half, 47%, are five-star ratings. The top 5-star review cites the Duracell Quantum as the top rated Consumer Reports alkaline battery, just behind Energizer's Lithium model. A top rating by C.R. is certainly a powerful endorsement.

In 2013, the company released a "Duracell Quantum" line as their top-performing alkaline batteries.

Quantum batteries have the potential to accelerate charging time and even harvest energy from light. Unlike electrochemical batteries that store ions and electrons, a quantum battery stores the energy from photons.

Duracell Quantum Alkaline batteries give you a one-of-a-kind quantum leap in power. It's the only battery with Hi-Density Core technology featuring more power boosters.

A battery is a device that stores energy: a quantum battery is no exception. In theory, it is a quantum mechanical system that stores the energy of photons rather than electrons and ions, as is the case with conventional electrochemical batteries.

What is a quantum? A quantum (plural: quanta) is the smallest discrete unit of a phenomenon. For example, a quantum of light is a photon, and a quantum of electricity is an electron. Quantum comes from Latin, meaning "an amount" or "how much?" If something is quantifiable, then it can be measured.

“At an atomic level, quantum computing simulates nature and therefore could help us find new materials or identify new chemical compounds for drug discovery.” Quantum technology is also having an out-sized impact on logistics management and route planning.

With a billion more molecules, for example, a quantum battery might be able to provide enough energy to light up a light-emitting diode. These devices could also be used in small electronic devices such as watches, phones, tablets, or laptops – in fact, any product that needs the stored energy.

A quantum battery is a quantum mechanical system in which energy is stored in an electromagnetic field or the qubits, charged by a stream of photons, i.e. in essence light.

The first wave of quantum technologies gave us the transistor. These devices became the foundation of modern computers and digital communication. Other examples of technologies powered by quantum mechanics include: MRI scanners for medical imaging.

Quantum computing uses the qubit as the basic unit of information rather than the conventional bit. The main characteristic of this alternative system is that it permits the coherent superposition of ones and zeros, the digits of the binary system around which all computing revolves.

The second was Quantum Theory, which proposed that energy exists as discrete packets - each called a "quantum." This new branch of physics enabled scientists to describe the interaction between energy and matter down through the subatomic realm.
