Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very differently to macroscopic matter: particles can behave like waves, and waves behave as though they are particles.

The field of Quantum Information Science (QIS) is a rapidly growing field, with an expanding number of potential applications that explore the capabilities of currently available noisy quantum devices and promise to eventually solve problems beyond anything that classical systems can accomplish. In the past few years, this expectation for transformational applications has translated to a lot of attention, both from the media (reaching the scientific community and the general public) and the government funding agencies and technology industry. The significant advances have been made in developing new techniques and algorithms and advancing quantum technologies, resulting in applications that are addressing real problems (albeit simplified, in most cases, or very specialized).

Eduard Babulak The central tenet of quantum theory that energy comes in indivisible packets called quanta is now explained in a classical way.

By showing the cause of the quantisation of the electron, the quantisation of light is also explained.
When considering applications for quantum computers, I recommend applying the accuracy test. For a given quantum computer system, determine the probability of getting the answer 7 when computing 3 plus 4.
Depending on the application, the lack of 100% accuracy might not be important but it is a point to consider.

When recent imho outright spectacular experimental results are both right and be confirmed independently, we all have some “simple“ microtubules based room temperature quantum computer in our head (water molecule rotating dipoles in 13 hexagon graphene tube) - and as it seems, not only there but even in plant live (RG link):

There have been many recent advances in the field of quantum computing, including:
To implement portable quantum computers, several fundamental properties of physics are essential:
As humans, we all do quantum computing in our minds, and that is how quantum mechanics was discovered, more than 100 years ago (no computers).
There has been a recent change in mathematics. Functions that are everywhere discontinuous are recognized and exemplified, since the end of 2022 [1], to be able to be differentiate and integrated exactly, and one can use that in a non-boolean setting. This also changes physics, and how quantum mechanics solutions can defensibly be calculated using rational numbers, that are everywhere discontinuous, and can compounded as "wheels within wheels".
On this basis, quantum computing can be considered to have begun in 2022 [1] and use the set Q in a non-boolean set. No complex numbers are used.

Developing portable quantum computers will require advances in miniaturizing and integrating quantum hardware, improving qubit coherence times, and increasing the efficiency of quantum error correction techniques. Progress in these areas will bring us closer to realizing the potential of practical, portable quantum computers.
Yousif Abdul Amer I think the claim by Google of quantum supremacy has to be taken in context:
See:
https://arxiv.org/pdf/2210.12753.pdf
The way I see it is that a quantum computer has been used in an application which is highly probabilistic and only requires a certain level of accuracy.
Very few practical computing applications are like this.

Kuantum fiziğinde birşeyin neye karşılık geleceğini ispatlamak için görmek ve anlamak çok önemli iki kavramdır. 1+2=3 olabilir de olmayabilir de. Önemli olan üç boyutlu uzayda veya evrenin herhangi bir yerinde bunu sağlamasıdır. Yani elma ile armutun ağırlıkları aynı olabilir ama şekilleri farklıdır. Aynı durumun tersi de olabilir. Bu durum bozonlarda, meteorlarda, uydularda, güneş sisteminde veya kainatın herhangi bir yerinde olabilir. Önemli olan yapılacak olan sistemin onu sağlayıp sağlamamasıdır. Yani sorun şurda olabilir. Bilgisayar tuşuna basıp 7 rakamını yazdınız ama aynı tuşla 6 yazabilirmisiniz. Durum bununla kısıtlı olmamalı ve yeryüzündeki birçok sorunda bundan kaynaklanıyor. Anlamak ve görmek.
