Quantum computing is a new era of computer technology that is extremely powerful.
Quantum computing is a new generation of
technology that involves a computer that is 158 million times quicker than the
world's most advanced supercomputer. It's a technology so powerful that it can
accomplish in four minutes what a regular supercomputer would take 10,000 years
to do.
Our computers have all been constructed
around the same design for decades. Whether it's NASA's massive equipment or
your personal laptop, they're all just glorified calculators that can only
accomplish one thing at a time.
All computers process and store information
in binary digits called bits, which is the key to how they work. There are just
two potential values for these bits: one or zero. According to the book
Fundamentals of Computers, these numbers generate binary code, which a computer
must interpret in order to do a certain operation.
WHAT IS QUANTUM COMPUTING?
According to the journal DocumentaMathematica, quantum theory is a field of physics that deals with the tiny
world of atoms and the smaller (subatomic) particles inside them. The
principles of physics are drastically different from what we see around us when
you descend into this microscopic universe. Quantum particles, for example, can
exist in several states at the same moment. Superposition is the term for this.
Quantum computers, instead of bits, employ
quantum bits, or 'qubits' for short. According to a report released at the IEEEInternational Conference on Big Data, a qubit can be a one, a zero, or both at
the same time, whereas a standard bit can only be a one or a zero.
This means that a quantum computer doesn't
have to wait for one process to finish before starting another; instead, it can
run both at once.
Consider the situation: you have a number
of doors, all of which are locked except one, and you need to figure out which
one is open. A typical computer would test each door one by one until it
discovered the one that was unlocked. Depending on how many doors there were,
it could take five minutes or a million years. A quantum computer, on the other
hand, could test all the doors at once. This is what allows them to move so
quickly.
Quantum particles, in addition to
superposition, show a bizarre behaviour known as entanglement, which is another
feature that makes this technology so revolutionary. When two quantum particles
are entangled, no matter how far apart they are, they form a relationship. Even
if they're thousands of kilometres apart, when you change one, the other
responds in the same way. According to the journal Nature, Einstein dubbed this
particle feature "spooky activity at a distance."
DESIGN LIMITATIONS
Quantum computers have a number of
advantages over regular computers, including speed and compactness. Computing
power doubles every two years, according to Moore's Law, according to the IEEE
Annals of the History of Computing. Engineers must, however, fit an increasing
number of transistors into a circuit board in order to do this. A transistor is
a miniature light switch that may be turned on or off. This is how a computer
interprets a binary code value of zero or one.
More transistors are required to address
more difficult issues. However, no matter how small you make them, a circuit
board can only hold so many. So, what exactly does that imply? According to the
Young Scientists Journal, this suggests that traditional computers will become
as smart as humans can make them sooner or later. This is where quantum
computers can make a difference.
The race to construct quantum computers has
morphed into a global contest, with some of the world's most powerful firms and
even governments seeking to push the technology even farther, triggering a
surge in interest in quantum computing stocks on the stock exchanges.
The D-Wave gadget is one such example.
According to a press statement from the corporation, it has constructed the
Advantage system, which it claims is the first and only quantum computer
tailored for corporate application.
D-wave claims that it has been created with
a revolutionary processing architecture that includes over 5,000 qubits and
15-way qubit communication, allowing businesses to tackle their most difficult
business challenges.
The company says that the machine is the
first and only quantum computer that allows clients to design and run
real-world, in-production quantum applications in the cloud at scale. When
compared to its previous generation technology, the Advantage is 30 times
faster and offers comparable or better results 94% of the time, according to
the company.
Despite quantum computers' enormous
theoretical computational capability, there's no need to toss your old laptop
in the trash just yet. According to Quantum Computing Inc., traditional
computers will continue to play a role in any new era, and are considerably
better suited to everyday chores like spreadsheets, emailing, and word
processing (QCI).
Quantum computing, on the other hand, has
the potential to revolutionise predictive analytics. Because a quantum computer
can execute analyses and predictions at fast speeds, it might anticipate
weather patterns and perform traffic modelling, both of which include millions,
if not billions, of factors that change all the time.
INSIDE THE D-WAVE
WHY DO WE NEED QUANTUM COMPUTING?
Standard computers are capable of doing
what they are instructed if they are fed the appropriate computer software by a
person. However, they are not so astute when it comes to forecasting events. As
a result, the weather forecast isn't always correct. There are far too many
variables, and far too many things are changing far too quickly for any
traditional computer to keep up with.
Because of its limitations, a conventional
computer may never be able to complete some computations, or it may take
billions of years to do so. If you need a quick prediction or piece of
analysis, this isn't the best option.
According to Rigetti Computing's research,
a quantum computer is so fast, almost endlessly so, that it could respond to
changing information swiftly and assess an infinite number of outcomes and
permutations at the same time.
Quantum computers are also smaller than
regular computers since they do not need transistors. They also use less
energy, which means they could be better for the environment in theory.
