Introduction To Quantum Information: A Guide to Nailing Quantum Computing Assignments

Why would quantum computers make terrible leaders? Because one could never be sure of the values they hold! Well, the peeps that are too invested in studying quantum computing would have found the joke in the previous line as both funny and unfunny at the same time, just like they find a quantum computing bit holding a value of “0” and “1” at the same time. Confusing isn’t it? When it comes to anything quantum, the laws of classical physics start to fade away and the notions of conventional time constructs start to break just like one’s confidence when one tries to approach a quantum computing assignment. Thank god that now technology is so advanced that one could avail Quantum Computing Assignment help from seasoned experts at My Assignment Services online. 

David Deutsch, the founder of quantum computing once said that if you think you understand quantum computing, you need to rethink. No one in this world truly understands what happens down there in the quantum world. But still, we attempt to estimate it. That’s what quantum computing is all about; probabilities. It’s natural for students into quantum information and quantum computing to look for some quantum computing assignment help. If you are one of those, you’d find essential information about quantum computing here as we unravel the mechanisms and principles at work behind quantum computing in this article. In the meanwhile, you could connect to experts at My Assignment Services, and get a solid high scoring assignment solution written for you. Before we get into understanding the mechanisms of a quantum computer, let’s check out an assignment question solved by our quantum computing experts.  

What’s a Quantum Computer? 

You can leave this article right about now if you are looking for a 60-second answer with all the buzzwords. But if you are truly looking to get a sense of understanding of what a quantum computer is, how it works and what quantumly entangled qubits are so crucial, you’d find this utterly resourceful!

Many science and tech journals have created hype around quantum computers like it would be leaps ahead from classical computers and have also propelled the notion that humanity would have supercomputer like powers in the handheld devices in the next few years. But the truth is that a Quantum computer is nothing like a classical computer and they are built specifically to solve mathematical problems that were previously too time-consuming for any classical computer to be solved. 

The current notion has boiled down the masterpiece of quantum computing to just the byte capacity of a qubit. Let’s debunk this notion. Let’s say even if a quantum qubit could hold a billion times more information than a classical bit, Google’s 53-qubit chip would be just equivalent to 6.6 Gbytes of classical storage. The smartphone you are currently holding would be probably able to hold more than 64Gbytes. 

Applications of a qubit are more than just holding more information than a classical bit. It is true that it can exist in 2 states simultaneously, and thus can store 2ntimes more information than a classical machine. Quantum computers shine truly when we talk about parallel computing and solving AI problems. 

Artificial Intelligence algorithms traditionally run on a GPU because of its architecture that can simulate multiple scenarios and calculate probabilities parallelly to help the algorithm learn from different scenarios and probabilities. Like a GPU a quantum computer is also super efficient at running parallel simulations and drastically cuts down the iterations of an algorithm to reach the desired result. To put it into perspective, the number of parallel operations that a modern GPU would perform in 10,000 Years, a quantum computer would simulate it in around 200 seconds. 

Classical GPU and CPUs can scale their parallel computing power linearly while the data generated by an algorithm may increase exponentially! Quantum Computer leverages concepts like Quantum Entanglement and Superposition to fabricate multiple calculations parallelly, and as the data generated by an algorithm grows exponentially, the quantum states that qubits can maintain also grows exponentially because a qubit can be both Zero and One at the same time. 

What Are Qubits? 

A classical machine stores and processes information with binary bits that can either hold a value zero or the value one. These values together work in combination to represent a character, integer, or other data types. 

Binary bits, known as qubits can also hold values like Zero and One, but they can hold these values at the same time. This is due to the superimposition phenomenon. The two values co-exist on a single qubit because the values of the qubit are determined by its spin. Every quantum bit has a spin, either positive or negative. This spn can be denoted as 1 or 0 in binary. However, at any given time there is a probability that a quantum bit may have an up spin, which is represented by and there may be a possibility of it having a down spin; the probability of which can be denoted by. 

Thus, at any given moment, the probability of a qubit having an up spin is represented by alpha and probability of it having a down spin by Beta. 

This can be represented by the equation: 

The diagram below tries to represent the superimposition of up spin and down spin.
