I’d guess 25- 40, given the requisite technology and cooling systems that take up whole warehouses.
We don’t have many since they aren’t particularly useful in our daily lives.
There is currently no actual large
scale quantum computer.
In terms of planned and possible applications, it is not yet a reality.
Large corporations, on the other hand, already have access to quantum technologies.
How many quantum computers exist?
Get rid of your outdated computers; the technological future is here!
It is quantum computing, not artificial intelligence or virtual reality!
And it has the potential to profoundly transform every part of our society, from healthcare to banking to national security.
A quantum computer is just a more efficient version of the ordinary computers you’re familiar with.
A traditional computer must filter through all potential responses one by one to discover the correct one, but a quantum computer can filter through one billion possible answers all at once to get the correct one in a fraction of a second.
The technology has evolved to the point that few people can program it, let alone operate it.
So, what kind of power and control would the first country or individual who perfected quantum computing wield?
It’s easier to grasp how quantum computers will impact your life if you first understand how they function.
Computers are now binary.
They work using bits, where each bit can either be a one or a zero, and nothing else.
A bit is a basic representation of one state or another, for as whether a light bulb is on or off.
A bit is represented by a current pulse or an electrical voltage in today’s computers.
Is it still the case that you’re with me?
We’re almost there, all right.
Information is processed using qubits in quantum computers.
These are identical to bits, except they may include both ones and zeros.
Imagine a sphere with both a north and a south pole, with the north pole representing “1” and the south pole representing “0,” to grasp the difference between bits and qubits.
The poles are the only useable spots on the entire sphere with a bit, and they may only be used one at a time.
The whole sphere becomes a useable zone when a qubit is used.
You don’t need to understand the underlying physics behind it to understand the key point: qubits can offer more sophisticated data and allow us to encode more information into much smaller processors.
Versions of this technology have already been created by some of the most forward
corporations, including Google, NASA, and IBM.
They’re now rushing to improve it.
Quantum computers, once completed, will provide several advantages.
For starters, they’d be a game
cryptography, thanks to their capacity to improve security protocols by creating really random numbers.
Because of this security, quantum
based communications devices
might be used to send medical and government records, defense data, and other sensitive things without worry of their falling into the wrong hands.
Calculating and processing large amounts of data more quickly would aid in the discovery of novel medications to treat ailments.
It would hasten the creation of life
Quantum computers would provide us the ability to better cope with climate change by allowing better software models to describe what is occurring in our environment, which might help us reverse climate change’s negative consequences.
But it’s not all good news; as we have stated, no one has yet mastered it.
We might all be in peril if the first person who do so intends to utilize the technology for nefarious purposes.
Our current cybersecurity measures will be rendered nearly ineffective once a functioning quantum computer is developed.
Encryption techniques now rely on massive arithmetic equations and problems that are nearly difficult to solve.
With its zero and one dualities, a quantum computer might be able to solve these algorithms quite quickly.
So I suppose we’ll just have to hope that one of the “good guys” figures it out before.
Perhaps we can use these early
generation quantum machines to improve future versions and make them more powerful, but that’s a discussion for another day.
There are eleven, according to public data as of June 2018.

The University of New South Wales’ Center for Quantum Computing and Communication Technology (http://www.cqc2t.org/) is a research institute dedicated to quantum computing and communication technology.
In the development of quantum computers, China has hit a crucial milestone.
D-Wave provides adiabatic quantum computers.
Types of quantum computers ?
The quantum circuit model, quantum Turing machine, adiabatic quantum computer, one
way quantum computer, and numerous quantum cellular automata are all examples of quantum computers (also known as quantum computing systems)

In the 3,000-
old game of Go,
Google’s AlphaGo AI acquired a commanding lead over the incumbent world champion, Lee Sedol.
On March 15, 2016, in Seoul, South Korea, the machine is presently 3-1 in a five-game series with one game remaining.
While IBM’s Deep Blue used sheer force to defeat reigning chess champion Garry Kasparov in 1997, Go is a game with more potential moves than there are atoms in the known world (literally).
As a result, the technology to perform such computations in a short period of time does not currently exist.
To beat the grand master, Google had to adopt a new approach: it needed to enable AlphaGo to self-improve using deep learning.
AlphaGo’s momentous choice is a watershed moment for artificial intelligence, and the IT world is now waiting to see what comes next.
Some think it’s defeating a human world champion in a real
time strategy game like StarCraft, while others point to quantum computing, a technology that has the potential to vastly increase AI’s capabilities. Thanks for reading.
