What is quantum computing

quantum computing

Quantum computing is the study of a non-classical model
of computation.
Whereas a classical computer encodes data into
fundamental units called bits, where each bit represents
either a one or a zero.
A quantum computer encodes data into bits that can
represent a one, a zero, or some combination.
QUANTUM COMPUTING perform calculations based on the
probability of an object's state before it is measured - instead of
just 1s or 0s - which means they have the potential to process
exponentially more data compared to classical computers.

Working of quantum
computing
In quantum computing, operations instead use the quantum state of an object to
produce what's known as a qubit. These states are the undefined properties of an
object before they've been detected, such as the spin of an electron or the
polarisation of a photon.
Rather than having a clear position, unmeasured quantum states occur in a mixed
'superposition', not unlike a coin spinning through the air before it lands in your
hand.
These superpositions can be entangled with those of other objects, meaning their
final outcomes will be mathematically related even if we don't know yet what they
are.
The complex mathematics behind these unsettled states of entangled 'spinning
coins' can be plugged into special algorithms to make short work of problems that
would take a classical computer a long time to work out... if they could ever
calculate them at all.
Such algorithms would be useful in solving complex mathematical problems,
producing hard-to-break security codes, or predicting multiple particle interactions
in chemical reactions
