The quantum confinement effect gives Carbon-based qubit, particularly spherical carbon quantum dots (CQDs) and nanosheets like graphene quantum dots (GQDs), exceptional features.
Recently, numerous reviews detailing their optical characteristics, architectures, and applications have been published in the literature.
These publications address a wide range of carbon-based nanoparticles, however they don’t go into great length regarding certain crucial issues like how to define Carbon-based qubit or how optical and electrochemical properties relate to sensing and medicinal applications.
These elements are the focus of this review’s major section. In particular, it seeks to serve as a link between the electrochemical and optical characteristics of carbon-based quantum particles, both of which are connected to the electrical nature of carbon.
The Global Carbon-based qubit market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Today’s quantum computers often store information in brittle quantum states that are challenging to scale up and maintain.
The high quality and practical manipulability of mechanical oscillators could be applied to quantum computing and sensing through a Carbon-based qubit that changes between two mechanical states instead.. Quantum devices with several Carbon-based qubitand lengthy qubit decoherence durations could be created using the idea.
By adding a controlled variation from simple harmonic oscillation, a mechanical oscillator can be converted into a Carbon-based qubit .
This deviation makes sure that a driving force can only excite certain energy levels, which correspond to the two states of the qubit. In the device ,this deviation would be accomplished by linking two quantum dots—”artificial atoms” with distinct electronic states—formed in the carbon nanotube itself to the flexural modes of a suspended carbon nanotube.
The researchers demonstrate theoretically how the qubit may be created in a certain state (one of the two lowest oscillation amplitudes of the nanotube) by adjusting the electron localization of the quantum dots. A microwave signal might quickly read the two states.
The researchers also demonstrate a logic gate’s implementation.The mechanical oscillators are a suitable quantum-computing platform because of their stable quantum states.
The oscillators, however, have the ability to detect minute changes in acceleration, gravity, magnetic moments, and electric forces because of their sensitivity to classical forces, the researchers claim.
