Abstract
The present invention relates to a quantum battery (1) for storing and supplying energy, comprising one or more clusters (2) for storing energy, each one comprising at least one quantum cell (3), wherein each quantum cell (3) has one or more quantum energy units (31), wherein each quantum energy unit (31) is a quantum system having a plurality of energy levels (|ϵ0)Aj,k, |ϵ0)Aj,k, . . . , |ϵd-1)Aj,k) to store energy. The present invention also relates to a method for charging and discharging a quantum battery (1).
Claims24
A quantum battery, comprising:
- one or more clusters configured to store energy, a first cluster of the one or more clusters comprising:
- at least one quantum cell comprising one or more quantum energy units, wherein a first quantum energy unit of the one or more quantum energy units comprises a quantum system having a plurality of energy levels (|ϵ0Aj,k, |ϵ1Aj,k, . . . , |ϵd-1Aj,k) configured to store energy.
A method for charging and discharging a quantum battery, the method comprising:
- charging the quantum battery by causing an energy exchange between quantum energy units disposed in at least one quantum cell and having a plurality of energy levels (|ϵ0Aj,k, |ϵ1Aj,k, . . . , |ϵd-1Aj,k) and an inner quantum bus having a discrete energy spectrum comprising a finite collection of frequencies ({ωB}) by applying, using a first control line, a resonant excitation between the inner quantum bus and the quantum energy units of the at least one quantum cell to cause a frequency of the finite collection of frequencies ({ωB}) to be in resonance with one of a level-spacing of an energy spectrum of a quantum energy unit of the quantum energy units.
