Quantum Computing: quantum computer

Quantum vs. Classical Computing

In the vast universe of computer science, two distinct species coexist: classical computing (old boy) and quantum computing (stunning juvenile).

Classical computing is the familiar realm, the workhorse of modern society. It’s binary, deterministic, dealing with ones and zeroes. It’s like flipping a coin – it’s either heads or tails, one or zero. Even if we talk about generating randomness on classical computers, we always use so-called pseudorandom number generators (with a seed that can be used to regenerate this ‘random’ result) – simply because genuine randomness does not exist in our world.

God does not play dice with the universe.

– as Albert Einstein once said. But was he right?

Well… Actually, he was so wrong!

And it was proven by many experiments based on Bell’s Theorem. There is a profound source of randomness when we look at our universe on a quantum scale (scale of elementary particles like photons, electrons, etc.). Quantum computing – an exotic creature that evolved on the foundation of quantum mechanics – doesn’t follow classical physics rules and the randomness of quantum particles is at its core.

In the quantum realm, that coin flip can land on heads, tails, or both at the same time!

Yes, you read that correctly, both at the same time! It’s like having your cake and eating it too – a phenomenon known as superposition. This fundamental departure from binary logic opens up quantum circuits to a world of possibilities, making quantum computing a game-changer in the field of computation.

Quantum Computing vs. Classical Computing

What is Quantum Computing? Let’s start with the basics

Quantum computing is a really complex beast, as it is based on quantum mechanics – the most complicated field of physics, but don’t worry. I’m not going to throw you into the deep end without a quick primer on quantum information and an introduction to the basics.

We have quantum bits or “qubits” at the core of quantum computing. Unlike the binary bits of classical computing (that can be either a one or a zero), qubits can be in a superposition of states, meaning they can be in multiple states at once. This is where the magic begins. When a qubit is in superposition, we don’t know its value until we measure it. When a qubit is in superposition, its potential value is reflected by probabilities of collapsing into a given state. Upon measurement (reading the value) qubit ‘collapses’ to 0 or 1, meaning that the qubit becomes a traditional classical bit with a well-defined value.

For example, a qubit can have a 50% chance of collapsing to 0 and a 50% chance of collapsing into 1 (the most random superposition you can achieve for a single qubit).

But we can also have a qubit with a 95% chance of collapsing into 0 and just 5% of collapsing into 1 – meaning that almost always the qubit will represent 0, but sometimes (precisely 5% of the time) it will become 1.

Another fascinating (or rather freaking mind-blowing) aspect of quantum mechanics (and a very important element for quantum computing) is entanglement. When qubits become entangled, one qubit’s state instantly reflects another’s quantum state, no matter the distance between them. This strange correlation, which Einstein famously called “spooky action at a distance”, allows qubits to work together in a way that classical bits simply can’t. And yet again, Einstein was wrong cause entanglement is a real thing proved experimentally, although we have absolutely no idea how it works. But in the end – what is important is that we can ‘connect’ qubits together.

Now, into the heart of quantum computing: imagine you could manipulate the probabilities of a qubit’s state in a controllable way so that qubits will collapse into desired state (solution of quantum computation). This can be achieved with quantum interference and it’s the secret sauce that makes quantum algorithms possible. Together, superposition, entanglement, and interference (that allows the creation of quantum logical gates) power the potential of quantum computing, making it possible to solve complex problems currently beyond the reach of classical computers.

Quantum Computing: QUBIT

How major Cloud Platforms are facilitating Quantum Computing

Quantum computing is no longer confined to the research labs of quantum physicists. Major tech players are entering the quantum race, bringing the power of quantum computing to the cloud. IBM, a pioneer in both classical and quantum computing, is making significant strides with its IBM Quantum initiative. They’ve developed a series of quantum computers, accessible via the IBM Cloud for free, that are pushing the boundaries of what’s possible with digital computers.

IBM’s Qiskit, an open-source quantum computing framework, allows users to run their quantum software programs on their personal devices and deploy them on IBM’s cloud quantum systems. Qiskit has effectively democratized quantum programming, making it accessible to a new generation of quantum enthusiasts. Whether you’re a researcher, a developer or an educator – Qiskit offers all the tools you need to explore the quantum realm.

Google Quantum AI is working to build quantum processors and develop novel quantum algorithms, aiming to harness the power of quantum mechanics to solve real-world complex problems. Microsoft is not far behind with Azure Quantum, striving to democratize quantum computing by offering developers a platform to access quantum hardware and other software development tools.

Amazon is also dipping its toes into the quantum waters with Amazon Braket, a fully managed service that enables scientists and developers to explore, create and test quantum algorithms. These tech giants are competing to create the most powerful and accessible quantum computing platforms, taking the field from theory to reality.

Quantum in the Cloud: Current applications and real-world use cases

Tantalizing possibilities of quantum computing are beginning to take shape, largely thanks to the pivotal role of cloud vendors. However, keeping our feet grounded in the present reality is important. While there’s a lot of potential, the current state of quantum computing still has limitations.

At present, we don’t possess quantum chips large enough to solve big-scale problems. Our quantum machines are still in their infancy, and we’re in the early stages of understanding how to make quantum circuits to get the best out of them. Quantum programming is currently a highly specialized field requiring a deep understanding of quantum physics. The use of quantum gates to manipulate qubits’ states is similar to classical programming using logic gates – yet on a vastly more complex scale.

Additionally, we’re still in the early days of developing the algorithms and physical systems necessary to harness the power of quantum computing fully. Availability for quantum computing on cloud platforms is a significant step forward (especially as we can use it mostly for free!), making quantum resources accessible for research and development, which will surely speed up advancements in the field.

The real-world applications of quantum computing are on the horizon, and the cloud will undoubtedly play a crucial role in bringing these applications to life. But for now, we’re still laying the foundations for quantum advantage and preparing for the quantum revolution.

Quantum Computing and Schrödinger’s Cat

Probably, you’ve heard about Schrödinger’s cat: a thought experiment that is one of the most famous examples of the weird and wonderful world of quantum mechanics.

Imagine a cat in a box with a vial of poison that can be broken at a random time – we can achieve it by putting some atomic substance and a Geiger detector with a trigger to break the glass of poison once it detects radiation. We know that the radiation of an atom is indeterministic – you cannot predict it – thus, it’s like a 50/50 chance of poison being released or not.

According to classical physics, the cat is either dead or alive. But quantum mechanics tells us that the cat is both dead and alive until we observe it (open the box).

This is similar to a qubit, where the quantum state determines the superposition state. It can be in multiple states at once until it’s observed or measured, at which point it collapses to a single state. This is the essence of quantum computing. We can manipulate qubits to be in multiple states at once, perform computations on them in this superposition state, and then observe the result collapsing the qubits to a single state. It’s like running many calculations simultaneously, which is why quantum computers have such enormous potential.

Shor’s Algorithm and the Quantum impact on data security

When we talk about quantum computing’s potential to disrupt traditional models, nowhere is this more apparent than in data security. Central to this is a quantum algorithm developed by the mathematician Peter Shor. Shor’s algorithm, designed to factor large numbers efficiently, has already sent ripples through the world of cryptography.

Most modern encryption systems, such as RSA, rely entirely on the fact that even the most powerful super (classical) computers take an enormous long time to factor large numbers. This is known as the integer factorization problem. However, Shor’s algorithm, when running on a sufficiently powerful quantum computer, can solve this problem exponentially faster than any known algorithm running on a classical computer.

Now, this doesn’t mean that all our online security is on the verge of collapsing. Today’s quantum computers aren’t powerful enough to run Shor’s algorithm at a scale that threatens current encryption methods. However, the existence of this algorithm has sparked a rush towards developing post-quantum cryptography. These encryption methods would remain secure even in the face of a quantum computing attack.

Will Quantum Computing replace classical computing?

It’s crucial to understand that quantum and classical computers are fundamentally different machines. They operate based on entirely different principles and are designed to solve different types of problems. This difference is precisely what makes the idea of one replacing the other a misunderstanding.

A more accurate perspective is to view quantum and classical computing as complementary forces. Just look at Shor’s algorithm, which exemplifies the synergy between a quantum system and classical computing. It consists of a classical part and a quantum part. The classical part reduces the problem of factoring a large number to the problem of finding the period of a certain function. The quantum part then solves this period-finding problem using the principles of quantum computing (Quantum Fourier transform to be precise). Once the period is found, the classical part again takes over to find the factors.

This symbiotic relationship between quantum and classical computing in Shor’s algorithm illustrates that quantum computers aren’t here to replace classical ones. They’re here to work alongside them, each excelling in their areas of strength. In fact, quantum chips could be seen as analogous to GPUs or TPUs in classical computers – specialized processing units to which specific tasks can be delegated. As we look towards the future, we can expect a computing landscape where a variety of computing technologies, including both classical and quantum computing hardware, coexist and complement each other.

The role of Quantum Computing in the Cloud’s future

The world of quantum computing is still in its infancy, but its potential impact on cloud computing is enormous. Imagine performing complex calculations in seconds, solving optimization problems with ease or simulating quantum systems accurately. Not even mentioning the so-called Quantum Artificial Intelligence – leveraging quantum mechanical properties to scale up neural networks training capabilities exponentially or from another angle – use AI and Machine Learning to develop new quantum algorithms like Shor’s one.

The future of quantum computing in the cloud is bright, but it’s also uncertain. Many technical hurdles still exist to overcome before we reach practical, large-scale quantum computers. But with the pace of research and the amount of investment in the field, it’s not a question of if quantum computing will transform the cloud, but when.

So, as we peer into the future of quantum computing research, one thing is certain: we are on the verge of a new era. An era where we can harness the power of quantum mechanics to solve some of the world’s most complex problems. An era where Schrödinger’s cat gets cozy in the cloud!
