What Is Quantum Computing?
Still fighting with the quantum era evolved? Let’s make a short trip to Quantum Computing world, functioning on Qubit.
There is a lot of buzz about Quantum Computing and Microsoft has officially announced Quantum Development Kit and Q#, language of Quantum Computing. But what defines Quantum? It is a branch of physics that deals with the world of atoms and subatomic particles inside them. And Quantum Computing is the area of study focused on developing computer technology based on Quantum Theory. But why Quantum Computers? The limitations of classical computers regarding the size of transistors made the world to come up with a secondary and more efficient solution of Quantum Computers. These are the machines build on principles of quantum mechanics, using qubits to process information.
Differences Between Classical Computers And Quantum Computers
Classical computers encode information in bits whereas quantum computers use qubits.
Quantum Computers can hold more information than classical computers and solve problems faster and more efficiently.
Superposition and entanglement are two properties of quantum computers.
In classical computers, engineers spend a lot of time trying to make sure the status of each bit is independent from that of all the other bits.And in Quantum computers, each qubit influences the other qubits around it.
A quantum computer uses the laws of quantum mechanics.
A quantum computer uses quits which is described as a 0 and 1 at the same time giving us more processing power. It will reduce time.
Pitfalls of using Quantum Technology-
Most importantly it will effect cryptographic encryption, which secures communications and computers.
Online privacy will be severely affected. Whatsapp works on encryption and decryption technology which will be lost when there is use of quantum technology.
Technology is not the solution. It often creates problem and that problem is tackled with Law.
It would be useful to regulate quantum computing now, or at least define the limits of its legitimate use.
Way forward-
Quantum technology/ computing will solve many unsolved or virtually solvable problems.
It can lead to the discovery of new medicine and materials.
It will not replace our computers but will open up a new universe of information and ability to solve complex problems.
Quantum technology can influence agriculture and human health.
It will help in developing new pharmaceuticals, new energy sources, new ways to collect solar power, and new materials.
What is a Qubit?
Just like in classical computers we have bits (‘0’ or ‘1’) similarly in quantum computers we have quantum bits- QUBIT. They have special properties where they can hold combination of ‘0’ & ‘1’ simultaneously. Quantum computing has two fundamental principles – Superposition and Entanglement.
It is the physical carrier of quantum information and can take values of zero, one, or both at once.
It can represent o and 1 at same time.
History of Quantum Computing
There is a technology called QUANTUM COMPUTING and the biggest players in this technological arena are Google and NASA who are teamed up with their D-Wave Quantum Computer to form the QUANTUM AI Lab. D-Wave is a very unique technology that is able to literally pull information/resources from other dimensions, the realm of the demonic.
In a very real way, D-Wave and the quantum computer technologies are a modern day OUIJA board.
The D-Wave computer is nothing like the one you are holding or, if you are at your desk, staring at right now. The D-Wave AQC (Adiabatic Quantum Computer) is an entirely different beast altogether. It is not a silicon computer like the ones Intel cranks out. The D-Wave AQC is far superior in design, construction, and ability. To start, lets have a look at the design of the D-Wave AQC processor.
According to Anthony Patch who has been heavily steeped in D-Wave research, the D-Wave AQC processor model 1024 has the same processing power equivalent to over 7 billion human brains, that is roughly how many human brains are in existence in the world today. Just let that sink in for a moment. He has also discovered that these things are sentient, as in self aware.
These D-Wave computers are what is at the heart of the current AI system today. That AI system is what is sucking up everything we do, say, read, post on social media, what we purchase on line. etc. and then using it all to learn about humanity and analyze us.
So far D-Wave has only gone public confirming they have achieved 2048 qbits on one chip to date, but Anthony Patch has discovered that they are actually at 4096 qbits which is a very significant accomplishment and will have a major impact on their progress toward using the D-Wave computer to control the ion stream at CERN once they figure out the correct formula to open the interdimensional portal which they most likely think the Awake Project at CERN will enable them to accomplish, in essence they are trying to rip the interdimensional veil between here and most likely hell itself.
Quantum computing is the use of quantum phenomena such as superposition and entanglement to perform computation. Computers that perform quantum computations are known as quantum computers.
Quantum computers are not replacement of classical computers but they are more accurate and speedy in comparison. We can synthesis new medicines, can develop new catalyst, accelerate AI development and a lot more using Quantum Computing.
Quantum Computer is a computation device which uses quantum-mechanical phenomena which is different from the usual digital computers working on transistors. Digital computers make use of binary digits for data encoding but quantum computing uses quantum bits (qubits). The concept was first introduced by Yuri Manin and Richard Feynman back in 1980s. Quantum Computing is still in its starting phase but lots of work is being done in the field. Full-fledged quantum computers will be able to solve problems much faster than classical computers.
What is quantum computer?
A computer which makes use of the quantum states of subatomic particles to store information.
Quantum computing provides numerous advantages over traditional computing. One of these benefits is that quantum computers can solve problems considerably faster than conventional computers; that is, quantum computers can analyze and process vast volumes of data, which is necessary for artificial intelligence and machine learning models.
In the news, Google claims “quantum supremacy” for its quantum computer, meaning their machine can solve some problems in a short time that would take an ordinary computer thousands of years. Many researchers and companies around the world are developing this next wave of computers. But what is a quantum? It seems that nobody has a clear answer, but they are part of who we are on a fundamental level.
Computer processing capability follows Moore‘s Law, which states that this capacity doubles every 18 or 24 months. Although not a physical law, but rather an observation of reality, this relationship of computational capacity increase has been used in practice since the 1970s. The increase in computational capacity allows AI algorithms to process the massive volume of data in the digital world more efficiently, and quantum computers have the potential to provide that power, allowing machines powered by AI models to reach a whole new level of capability and learning potential. According to the consulting firm McKinsey, quantum computing will have between 2,000 and 5,000 devices worldwide by 2030.
QUANTUM SUPREMACY
Google has claimed that it has achieved a breakthrough called Quantum supremacy in computing. It would solve those problems which are beyond the computational capabilities of a present day computer.
What is quantum Supremacy?
It was first discovered in 2012 by John Preskill, professor of theoretical physics at the California Institute of Technology.
Google’s scientist have claimed that they developed a processor that took 200 seconds to do a calculation that would have taken a classical computer 10,000 years.
What is “quantum supremacy” and why is Google’s breakthrough such a big deal?
Here’s what it might mean for you and for the future of encryption.

Google made a huge revelation on October 23, 2019, when it announced that it had reached something called “quantum supremacy.”
Via an article in the journal Nature, Google said their quantum computer, called Sycamore, solved a particularly difficult problem in 200 seconds. For comparison, Google said the world’s current fastest classical computer — one called Summit owned by IBM that’s as big as two basketball courts — would take 10,000 years to solve that same problem.
This is what “quantum supremacy” means. It’s when a quantum computer — one that runs on the laws of quantum physics as opposed to the classical computers we’re familiar with (i.e. phones and laptops), which run on classical physics like Newton’s laws of motion — does something that no conventional computer could do in a reasonable amount of time.
The trouble here is that IBM responded to Google’s news to say that actually, Summit could solve the quantum computers’ problem in two and a half days — not 10,000 years as Google had suggested.
In this episode of Recode’s Reset podcast, host Arielle Duhaime-Ross and Kevin Hartnett, a senior writer for the math and physics magazine Quanta, break down exactly what quantum computing is and why Google dunking on IBM both was and wasn’t a huge deal.
“It’s insane because if we build a working quantum computer, it demonstrates that we have achieved a kind of physical mastery over matter in the universe. At the most fundamental level, we are controlling it. We’re manipulating it to our own ends and we’re performing calculations with it and we’re performing calculations with it. That’s kind of stunning. And the fact that engineers are now actually pulling this off is kind of amazing,” Hartnett pointed out.
Later in the episode, the two also dive into what applications a working quantum computer would have in the real world from pharmaceutical drug discovery and financial modeling to breaking the internet by undoing a common form of encryption called RSA encryption.

”Right now, that’s how we keep a lot of information on the internet safe. But with a very powerful quantum computer? … the time it takes to break a large number down becomes really short. And that means the key you use to encrypt stuff is easy to figure out ?and the internet is kinda screwed. But that is still mostly theoretical at this point?,” Duhaime-Ross explained.
