What are QCs? Why are they disrupting our current views on computation?

Classical Computers: What they cannot do?
Exponential Scaling
Optimization problems
Chemical Compound Representation/Simulation
Security Encryptions
All of these problems have exponential scaling in common
This is a major hurdle with our classical computers and supercomputers too
Church-Turing Thesis
Accepted rule: It states that if a problem can be solved by a Turing machine, it can also be solved by a computational device.
Extension on the Thesis: It states that a Turing machine (like a classical computer) can always efficiently simulate any computational model, even to simulate an inherently quantum computation.
Quantum Supremacy and what it beholds
Quantum computers could efficiently solve a computation that a classical computer can only solve inefficiently, is known as Quantum Supremacy
Google Quantum Supremacy- What did they do?-News article with technical terms
Later-after qubit-Theoretically, if you reach a certain number of efficient qubits, usually said to 56, you can thereby simulate problems that a Classical computers nowhere can

Superconducting Bits
Electrical Circuits to generate qubits
Sycamore The 54-qubit QC by Google
Compared to IBM, they actively release blogs and had a chance to meet one of them
Qubits and their properties
Qubits or quantum bits are the fundamental building block for quantum information processes.
Whereas conventional computers store and process data as a series of '1's and '0's. Quantum Computers can use Qubits.
Property of Superposition
Property of Entaglement
Quantum Supremacy slide
Property of Superposition
At any given time, the qubit can be in a superposition of both 0 and 1
Hence you are expanding your information space and this becomes more complex
Property of Entaglement
Quantum State of each particle cannot be described independently of the state of the others, even when the particles are separated by a large distance.
So you can judge an adjacent's qubit's property by this qubit
Why do QCs have different rules to play by?
Limitations of QCs: Suprise Quantum Computers aren't perfect.
